Snow & Ice Control Meeting Signals Winter’s Approach to Chicago Executive Airport

BlowerThe FAA’s new runway Takeoff and Landing Performance Assessment (TALPA) was the major change discussed at the recent Snow and Ice Committee meeting the tenants and users of Chicago Executive Airport, said Andrew Wolanik, PWK’s operations coordinator. Not only does it change how the airport operations crew determines the runway conditions, it changes how those conditions are reported to the airport’s users.

The federal NOTAM (Notices to Airmen) system will now be the primary method of disseminating runway conditions to all users at every airport including air traffic control. To test the system’s latency, the time it takes the surface condition NOTAM to reach the control tower from the the operations keyboard, Wolanik conducted several tests. The results were the same: the tower’s fax machine spit out the test NOTAM 90 seconds after he punched the submit key. Per a freshly revised Letter of Agreement between the air traffic control tower and airport management, airport operations must either radio or call the surface condition NOTAM directly to the control tower as well.

How runway conditions are assessed and communicated aren’t the only changes in the airport’s snow and ice control plan. In revising the plan for the 2016-17 season, the staff used Part 139 requirements as a guide, said Wolanik. “We are not an airport that serves commercial airlines, but we strive to meet and exceed the level of safety, and working to Part 139 snow and ice control requirements further improves Chicago Exec’s general operating standards and safety.”

Those standards include staff review of all applicable standards right down to the height of snow banks. If they are too high, not only can they damage aircraft they can block signs, lights, and markings and impede the accuracy of essential navigational aids. Training is another requirement, and the entire operations crew is cross-trained on every piece equipment. And that fleet of plows, brooms, and blowers will grow by one with the arrival a new Oshkosh H-series rotary broom, which will be designated Airport 20, in February 2017.

NPIAS Report to Congress Lists Five-Year Airport Improvement Program Eligibility

ILThe FAA recently sent Congress its National Plan of Integrated Airport Systems (NPIAS) for Fiscal Years 2017 to 2021. Since 1984, the report has identified the airports that make up the national airport system, they role the play in it, and the types of airport development they are eligible for and the amount of Airport Improvement Program (AIP) funding to help pay for it over the next five years.

Chicago Executive Airport (PWK) is one of 3,340 public-use airports (3,332 existing and eight proposed) “that are important to national air transportation. This year the FAA estimated that these airports will need approximately $32.5 billion in AIP-eligible projects between 2017 and 2021. All commercial airports are included in the report, as are a smaller number of general aviation airports that make specific contributions to the NPIAS.

Digging deeper into the report, the FAA lists Chicago Exec as a National Reliever, and it is eligible for $83,851,701 in AIP funds. That’s not a guarantee, just the estimated maximum amount of AIP funding the airport is eligible to apply for. The report does not list specific projects. That involved process, which involves the airport, local and state authorities, as well as the FAA are the next steps.

As the report explained, airport improvements grow out of current and forecasted traffic at each airport, the use and age of their facilities, and changing technology that requires airports to upgrade or replace the equipment and infrastructure that supports them. The FAA works with state aviation agencies and local planning organizations to identify public-use airports for inclusion in the NPIAS.

imageThe FAA said AIP projects are expected to decrease at large and medium-sized hub airports and increase at small hubs. “Development at all other airport categories remain flat.” Contributing to this is the conclusion of the FAA’s decade-long airport capacity effort and runway safety area (RSA) initiative. This included Chicago Exec’s EMAS, which recently demonstrated its contribution to safety and is pictured in the report.

In the NPIAS hierarchy, there are 395 primary airports (think O’Hare and Midway) that handle the majority of the nation’s commercial (airline) traffic. Logically, the remaining 2,937 NPIAS airports are nonprimary.

On this list, Chicago Exec’s listing assigns it a National role, meaning it “supports the national airport system by providing communities access to national and international markets in multiple states and throughout the United States. National airports have very high levels of aviation activity with many jets and multiengine propeller aircraft.”

And it is categorized as one of the nation’s 259 Reliever airports, defined as “An airport designated by the Secretary of Transportation to relieve congestion at a commercial service airport and to provide more general aviation access to the community.” And doesn’t that succinctly summarize Chicago Exec’s contribution to the communities that surround it as well at the nation in which it plays a significant role?

New Runway Takeoff & Landing Performance Assessment Starts October 1

matrixWhen the weather is not sunny, dry, and clear, pilots preparing to takeoff or land need to know what condition the runway is in. To improve these reports, the FAA and aviation community have developed new standards to improve safety during inclement weather. Airports will begin using the new Takeoff and Landing Performance Assessment (TALPA) standards on October 1, 2016.

The new standards communicate runway conditions in terms directly related to their affect on aircraft performance. Airport operators will employ the Runway Condition Assessment Matrix (RCAM) to report runway conditions. The matrix is a standardized format that is based on aircraft performance data supplied by the airframe manufacturers for the type and depth of each runway contaminant.

The new standards replace subjective judgments of runway conditions that are now reported with a Mu number that describes a coefficient of braking friction. Using the FAA example of this system, a runway covered with 2 inches of dry snow would be reported as: “FICON 2IN DRY SN OBSERVED AT 1601010139. 1601010151-1601020145” along with Mu values as “TAP MU 29/27/29 OBSERVED AT 1601010139. 1601010151-1601020145.

Starting October 1, these conditions would be reported this way: DEN RWY 17R FICON (5/5/3) 25 PRCT 1/8 IN DRY SN, 25 PRCT 1/8 IN DRY SN, 50 PRCT 2 IN DRY SN OBSERVED AT 1601010139. 1601010151-1601020145. With this information, pilots would then consult the aircraft flight manual to determine what performance they can expect from their airplane. Note that the numerical Runway Condition Codes, based on the RCAM, subdivide the runway into three segments when the contaminants vary.

Airport operators will assess the runway surfaces, report the contaminants, and use the RCAM to determine the Runway Condition Code. The same code can cover the entire runway when there is no variation in the contaminant. These codes will replace Mu numbers, which the NOTAM system will no longer use.

This does not mean pilots should stop reporting braking action. They will still be used and shared. However, the terminology used in these reports will change on October 1. “Medium” will replace the “Fair” braking action assessment. And airports will no longer be able to report a “NIL” braking action condition. Under the new system, NIL conditions require airports to close that surface until they are satisfied that the NIL braking conditions no longer exist.

Chicago Exec urges aircraft operators to review the appropriate performance sections of the aircraft flight manuals for their airplanes and develop procedures that will enable them to take full advantage of the new runway condition reports.

Airport Interns at Chicago Exec Get First-Hand Air Operations Area Experience

PWK-28Mowing grass and whipping weeds may seem a mundane, menial summer job, but that’s not true at Chicago Executive Airport. As the four airport interns are learning this summer, these tasks are an excellent first-hand lesson in life in an airport operation area. Often referred to as the AOA, it is defined as any area of an airport used or intended to be used for takeoff, landing, or surface maneuvering of aircraft. This includes paved and unpaved areas, including runways, taxiways, taxi lanes, ramps, and aprons.

In other words, the AOA is everything inside the airport fence, and nothing moves within it without the FAA control tower knowing about it. Anything that moves on the airport, airplanes, helicopters, trucks, lawn mowers, or interns with a weed whip, must be cleared for the movement by the tower so there is not an unfortunate, unintended meeting of any two of them, explained James Kelly (below), a Tinley Park-native who will start his senior year at Lewis University, where he’ll earn a degree in aviation administration, with a minor in flight dispatch.

The students started their internships with a class that certified them to drive on the AOA. Working with an airport diagram they learned where they could and could not drive, how to identify their location on the airport and read the signs and pavement markings that identified them, and how to communicate with the tower’s ground controller.

“We got a tour of the tower,” said Conner Wagner, (on right, with Will Thompson and “their” truck, Airport 8) who hails from Jackson, Michigan, and graduates in 2017 with a degree in aviation management operations with a minor in business from Western Michigan University. “It was interesting to see how the controllers coordinate all the activity on the ground and in the air, all the vehicles and planes in the airport operating area.” A classmate, Brendan Stauton, is also interning at PWK this summer. Working toward a professional pilot degree, he’d returned to campus to take the FAA checkride for his instrument rating, which he passed, said Wagner.

PWK-34In accordance with the airport’s wildlife management plan, the interns mowing efforts are coordinated so that the grass stays between 5 and 8 inches in height. Any shorter and insects would be readily visible, attracting their predators, and any longer would provide too much cover for mammalian prey from their predators. And while they are mowing or whipping weeds, the interns are looking for animals, inspecting the fence line for places where animals have dug under the fence, and keeping an eye out for burned out airport lights.

After reporting a burned out light, the interns learned how to replace them under the watchful eye of a member of the airport maintenance crew. Airport Operations Coordinator Andrew Wolanik and Assistant Airport Operations Coordinator Bryce Walter are the interns’ primary supervisors. Mowing and whipping occupy roughly half their time. They have undertaken any number of different airport projects. In the week before Independence Day, they were building 180 sets of wheel chocks from scratch. They will secure the airplanes moved from their usual homes in Areas 2 and 3, so the airport would have someplace to park cars for Chicago Exec’s July 4 weekend activities.

Three of Chicago Execs four summer interns learned about the opportunity through the aviation degree programs in which they are enrolled, and their summer efforts are bookended by the end of the last school year and the start of the next. Will Thompson of Winnetka, a political science major who just finished his freshman year at Villanova University in Philadelphia, Pennsylvania, learned about the program from PWK Civil Air Patrol unit he joined in 2014. His internship is shorter than the others. With his sights set on being an aviators, “I’m in U.S. Marine ROTC, and I have some training to do before school starts.”

Making Chicago Exec Better, Safer, More Efficient is Goal of New Airport Operations Coordinator

Andrew WolanikChicago Executive Airport’s new airport operations coordinator, Andrew Wolanik, who started work just before the year 2016 began, describes his responsibilities and his goals in simple terms. “Basically, I’m responsible for everything inside the airport fence and with the airport operations maintenance crew our goal is to make Chicago Exec a better, safer, more efficient environment for resident and visiting aviators and businesses.”

This ranges from seemingly mundane tasks like cutting the grass and coordinating the snow removal teams to other equally important tasks, like the daily inspection of all airport pavement for FOD, and removal of these items that can cause expensive Foreign Object Damage when an aircraft runs into or over it, or sucks it into an engine. Worldwide, FOD costs aviation about $13 billion a year, and the administration team does not want operations at PWK to add a penny to that total and, more importantly, doesn’t want anyone to get hurt.

“Runway 16 is 150 feet wide, and it is hard to see all of it, and to make sure the lights that line it, are in optimum operating order on a single pass,” Wolanik explained. So he updated the inspection routes defined by a standard operating procedure to increase the number of passes to give the pavement and lights a more thorough visual inspection, and the airport recently acquired a drag-behind 72-inch FOD magnet that collects the ferrous FOD that’s hard to see.

Coordinating snow removal operations is even more involved. Beyond scheduling the six full-time maintenance crew to shifts that ensure a continuous effort during the storm, Wolanik must employ the right equipment, the plows, rotating brooms, and snow blowers, in the proper sequence that is predicated on the type of snow. There’s a big difference between 2 inches of dry, light snow and 6 inches or more of the heavy wet stuff. And then there is ice. Dealing with it requires almost constant measurement of air and pavement temperatures, which play a critical part in the effectiveness of the anti-icing fluid sprayed on the pavement.

Discussing ways to improve the airport’s operating procedures—and address new challenges—is a collaborative effort most easily seen at the team’s regular safety meetings. The team, which this summer includes four interns, is more like a family, said Wolanik, and this in one of the leading reasons he applied for the position.

Wolanik, who graduated from Lewis University n 2010 with a degree in aviation administration, became a member of this family during his summer internships in 2009 and 2010. “Those were memorable summers,” said the Lake in the Hills native. “I had a lot of fun learning from people who became friends (some of whom attended my wedding), and I always wanted to come back here.”

Between graduation and joining the Chicago Exec family full time, Wolanik worked as a senior logistics coordinator at Priester Aviation, he said. This experience not only added an aviation dispatcher rating to his FAA certificate as an instrument-rated private pilot and advanced ground instructor, it gave him valuable insights on how general aviation operations work affects the operations of PWK’s aviation businesses. It is an important component of his holistic approach to making Chicago Exec a better, safer, more efficient place to fly.

Assistant Airport Operations Coordinator Builds Career on Chicago Exec Internship

PWK-17A full-time position as the assistant airport operations coordinator was the last thing Bryce Walter expected when he secured an internship at Chicago Executive Airport. Receiving the offer in mid-December 2015 for the internship that started with the New Year, the Grand Rapids, Michigan, native’s immediate concern was finding a place to live. “All my friends told me I needed to get a place in the city, because there are a lot of fun things to do there,” he said, and they were right. Now building a career and future at Chicago Exec, he’s looking for a place closer to the airport.

Completing his degree in aviation management operations at Western Michigan University in August, Walter briefly considered a flight degree, and earned his private pilot certificate in the process, but quite a bit of job shadowing at the Grand Rapids airport revealed greater opportunity and a more diverse series of challenges. “But the initial hurdle is that nobody wants to hire someone in operations who doesn’t have experience, so I knew I needed an internship to get some. I started looking and found that not a lot of airports want to help people get started with internships.”

In the end, he found three, and his final choices were Aspen, Colorado, and Chicago Exec. “I’ve been to the Chicago area quite a bit, and it was more appealing than Aspen,” said Walter. And it’s closer to home, where he and a partner run a wedding DJ business. “During the 2016 season I’m only doing one wedding a month,” he explained, adding that his business partner is “really slammed.”

Airplanes, Airspace & Chicago Executive Airport

Terminal ChartTo those on the ground, airspace is invisibly boundless. All that changes in an airplane. To make flying safe for pilots, their passengers, and people on the ground , the sky is subdivided into unseen slices delineated by altitude and distances from specific points on the ground, like airports. In each of five airspace categories, pilots and aircraft must meet specific training, equipment, and procedural requirements, from weather and visibility minimums to getting clearance from air traffic control before crossing one of these invisible dividing lines.

Naturally, the more airplanes and airports there are in a given area, the more complex the airspace, like that which covers Chicagoland. O’Hare International (ORD) anchors the angular funnel that is Class B controlled airspace, which is roughly 10 nautical miles in diameter where it touches the ground. When measured east to west, the top of the funnel, at 10,000 feet, is 60 nautical miles in diameter. If O’Hare was the only airport covered by this funnel, guiding airliners to and from it would be a simple matter. But it is one of roughly 16 public and private aerodromes, one of which, Chicago Midway (MDW) is encompassed with its own bubble of Class C controlled airspace.

Looking at the Chicago Terminal Area Chart above, Chicago Executive Airport (PWK) is easy to find. It is in the notch cut into the 5-to-10-nautical mile ring that encircles O’Hare. That cutout raises the floor of Class B airspace, entry into which requires an air traffic control clearance, from 1,900 feet in the rest of the 5-10-mile ring to 3,000 feet, as do the corner slices adjacent to the PWK notch.  Those wide blue tinted lines cutting through the rings denote the recommended paths and altitudes for pilots flying under visual flight rules beneath the Class B airspace.

And it is a busy airspace funnel. The FAA’s Air Traffic Activity System tracks and reports the number of operations (takeoffs and landings) at airports with control towers and the number of airplanes fed to those airports by the air traffic control facility responsible for the airspace, which for Chicagoland is located in Elgin. In 2015, it handled 1,248,503 operations, with 782,905 of them being airliners, most of which were on their way to O’Hare or Midway. That same year Elgin routed 318,434 air taxi (aka charter flights) and 110,407 general aviation operations to their destinations.

PWK NotchPlugging Chicago Executive Airport into the Air Traffic Activity System showed that in 2015 its control tower handled 76,901 operations. Of that number, the FAA classified the majority of them “IFR Itinerant,” meaning the airplanes taking off or landing were going to or coming from some other airport. Of the 34,188 such operations in 2015, general aviation accounted for 21,719 and air taxi (charter) tallied 12,376. It’s a busy place that is a notched neighbor of an even busier place.

The point is that each operation represents an airplane that’s going someplace, either starting or concluding its flight. The floor of the Class B airspace over Chicago Exec starts at 3,000 feet and climbs to 10,000 feet. Nearly all business jets depart PWK on an instrument flight plan. Before takeoff, air traffic control  clears them through and out of Class B airspace on a specific departure route that keeps them safely separated from all the other airplanes flying in the funnel. ATC reverses the process for airplanes bound for Chicago Exec.

When the weather is good, most of the other general aviation traffic, from people flying their own planes on business or for pleasure and newcomers learning to fly, stay out of Class B airspace by flying beneath its floor. Over Chicago Exec, that’s 3,000 feet, but directly east or west it quickly descends to 1,900 feet with steps down in the adjacent transition areas. So when you look up at the sound of an airplane flying over, see no other airplanes in the immediate vicinity, and wonder why it is so low, remember that the pilot is avoiding the invisible layers of the Class B airspace, and that this single airplane is just one of more than a million making its way to or from Chicagoland every year.

Airport 101: Signs Point the Way at Chicago Executive

PWK-19As they do around town, signs tell pilots where they are on Chicago Executive Airport and point the way to the runway and ramp and the taxiways that connect them. The only difference is that airport signs are color coded, lighted, and much closer to the ground on their frangible mounts. And they are sometimes painted on the pavement, usually identifying positions on low visibility taxi routes. In all, there are six types of airport signs. They relay mandatory instructions, location, direction, destination, information, and runway distance remaining.

Mandatory instruction signs are red with white letters and identify critical areas, such as the entrance to a runway or areas where aircraft entry is prohibited. Runway hold position signs are adjacent to the yellow hold short markings on the pavement and their alphanumeric display identifies the intersecting runway. If the taxiway intersects the runway at midfield, the runway numbers on the sign correspond, left and right, to the respective runway’s threshold.  Similar signs that bear a runway number and APCH or ILS indicate holding positions that keep aircraft a safe distance from the runway in foul weather so they do not interfere with instrument approach operations or the electronic systems that are guiding pilots to the runway.

Location, direction, and destination signs use combinations of yellow and black. Taxiway location signs use yellow characters on a black background with a yellow border. Often they are connected to direction or runway holding signs. Direction signs use black symbols in a yellow background and identify the intersecting taxiway with its alphanumeric designator and an arrow pointing in the direction a pilot would normally be expected to turn.

Direction signs are generally located on the left side of the taxiway before an intersection. If there is more than one way to go, the taxiway designations and their associated arrows are displayed clockwise starting from the first taxiway on the pilot’s left.

PWK-17Information signs have black characters on a yellow background and provide pilots with all sorts of pertinent information such as applicable radio frequencies or noise abatement procedures. Their content is determined by each airport’s operator.

Runway distance remaining signs are white numbers on a black background and are installed along one or both sides of a runway. The number indicates the distance, in thousands of feet, of the remaining useable runway. The last sign—1—will be at least 950 feet from the end of the runway.

All signs work in conjunction with pavement markings, which correspond to each airport’s diagram. The diagram is the pilot’s airport map that shows and names each runway and taxiway that lead to ramps and hangars and fixed-base operators. And at airports with towers, like Chicago Exec, the ground controller provides them with a taxi clearance that delineates their route from point to point, and will provide progressive instructions to newcomers that will lead them, turn-by-turn, to where they want to go.

Airport 101: Pavement Markings Keep Pilots in Line

PWK-59Chicago Executive Airport is one of thousands of airports that dot the American landscape. Each of them is different, but pilots have little trouble navigating around them because each of them use standardized pavement markings on the taxiways and runways that safely and efficiently guide them from the ramp to the sky. (Although they didn’t offer much help to the runners who raced about the airport several years ago, but they did get to see them at close range.)

Runway markings are white, and the elements employed depend on the type of approach pilots make to it. Runways with visual approaches, where the pilot eyeballs his arrival, has the fewest markings, the runway number, which is its magnetic heading to the nearest 10 degrees, and a centerline. These are on all runways. If the strip is 4,000 feet or longer or used by jets, it will have a visual aiming point, two broad white stripes on either side of the centerline approximately 1,000 feet from the threshold.

If it is intended for commercial use, markings (either a series of longitudinal or one lateral stripe) identify the pavement suitable for landing. A number of airports, like Chicago Exec, have displaced thresholds, usually to ensure an airplane’s safe approach to touchdown. Arrows on the pavement point to where the legal landing area begins.

All runways served by a nonprecision instrument approach, which in bad weather provides horizontal guidance to the runway, have these four markings. Chicago Exec has precision instrument approaches leading to both ends of Runway 16, which also provides vertical guidance to the pavement, which is why it has a touchdown zone. The rectangular bars are arranged in symmetrical pairs spaced 500 feet apart. As the number of bars decreases, so does the length of the remaining runway. Precision runways also have side stripes.

PWK-34All taxiway markings are yellow, and a centerline and markings denoting holding positions are common to all of them. A continuous strip 6 to 12 inches wide, the centerline does not guarantee wingtip clearance with other aircraft or obstacles. A line indicating the edge of the taxiway is applied when it does not correspond to the end of pavement.

Chicago Exec has an enhanced centerline, yellow dashes that parallel the continuous centerline, which tells pilots they are approaching a runway holding position and should be slowing down and preparing to stop, or hold short of the runway or intersections. Hold-short markings have two solid stripes on one side and two dashed lines on the other. Airplanes must stop when approaching the solid lines, which are on the taxiway side of a runway intersection. They may continue without stopping when on the dashed-line side, which they face when exiting the runway after landing.

Solid white lines on either side of a dashed centerline denote the edges of vehicle roadways that cross pavement also intended for aircraft. Some airports also use “zipper” markings, alternating white blocks. In either case, aircraft have the right of way. A thick white block on the pavement denotes where vehicles must stop at intersecting roadways or before crossing taxiways or other operational areas.

Working in concert with an airport’s pavement markings are a variety of signs of different colors that tell pilots where they are on the airport, and which way they should turn to reach their desired destination whether it is the departure end of a runway or a parking area. We’ll introduce them in our next Airport 101.

Airport Considers Noise Abatement Procedure

 

PWK noise test map 7-2016

Runway 34 departure procedure proposes aircraft fly a 310 heading for a short while after takeoff.

Just ahead of next week’s quarterly airport noise committee meeting – March 9 at 6:30 pm – Executive Director Jamie Abbott is asking users for comments about a potential noise abatement procedure the airport is considering. The airport may ask for the procedure to be tested at night for a six-month trial period, to obtain public input on the noise associated with northbound nighttime PWK departures on residents north of PWK.

The procedure, included in previous Part 150 Noise Studies, would propose that turbine-powered aircraft departing runway 34, from 10:00 PM to 7:00 AM, to fly a 310 degree heading as soon as practicable after takeoff.

Aircraft would climb on this heading until reaching Lake Cook Road before proceeding on course, or to comply with further instructions issued by Chicago Departure Control. VFR aircraft would be asked to comply when able and with PWK tower approval.

The trial period would run daily between 10:00 PM and 7:00 AM.

The airport would like to hear what users think before the airport requests the six-month trial from the FAA. Send your comments to Jamie Abbott at jabbott@chiexec.com.
