Opposing Bases: Air Traffic Talk

I just found a series of podcasts hosted by a pair of working air traffic controllers who are also pilots: Opposing Bases: Air Traffic Talk

Welcome to Opposing Bases: Air Traffic Talk.  Our aviation podcast is delivered by two experienced pilots that work as air traffic controllers.  We fly in the NAS and we interact with the community through our podcast.  Our show is driven by your feedback and questions.  Enjoy the show and thanks for listening!

ADS-B and Call Sign Confusion

The ADS-B mandate has arrived, and with it comes the potential for another source of confusion. Most pilots flying with ADS-B systems have a display of traffic in the cockpit, either on a moving map that’s part of a GNSS navigation system or on a tablet like an iPad running an app such as ForeFlight, Garmin Pilot, or FlyQ. These traffic systems usually show the identification of other aircraft, either the registration number or the airline flight number.

When ATC issues traffic advisories–for example, “Cessna 1234A, traffic 2 o’clock, 4 miles, a Southwest 737”–it might be tempting to include the target identification in your acknowledgement. For example, “Cessna 1234A, we have Southwest 2345 in sight,” or “Southwest 2345 in sight, Cessna 1234A.”

If that sounds odd, watch some aviation videos on YouTube. At least one pilot flying an airplane with a new glass panel has made a habit of such replies.

For obvious reasons, it’s a bad idea to include another aircraft’s identification or call sign when you respond to ATC. In fact, the FAA’s December 2019 update to AC 90-114 Automatic Dependent Surveillance-Broadcast Operations anticipates this issue:

2.4.3.4 Unless initiated by the controller, pilots should typically not use the call sign or Aircraft Identification (ACID) of observed traffic in radio communications, as this could create confusion for both ATC and pilots monitoring the frequency.

AC 90-114B

So even if you’re equipped with the latest technology, stick to the standard replies when ATC points out traffic:

“Cessna 1234A, traffic 2 o’clock, 4 miles, a Southwest 737.”

“Cessna 1234A, we have the Southwest 737 in sight,” or “Traffic in sight, Cessna 1234A.”

FAA Completes ATC Phone Number Plan

The February 25, 2019 issue of FAAST Blast includes the following item about FAA’s plan to publish ATC telephone numbers in the Chart Supplement. You can read more details and see examples at earlier entries here at BruceAir:

Leidos FSS has posted ARTCC clearance/cancelation phone numbers on its website, here.

FAA Completes Clearance Relay Initiative

Flight Service will complete the Clearance Relay initiative on June 20 when it publishes the remaining phone numbers for pilots to obtain IFR clearances at public- and private-use airports, from either the overlying Air Route Traffic Control Center (ARTCC) Flight Data Units, or an approach control facility. As part of modernization efforts to streamline service delivery and increase efficiency, pilots now call directly to obtain or cancel an IFR clearance, reducing the risk of potential errors.

Last year, Flight Service formalized a process already in place by publishing phone numbers for 30 approach controls covering 667 public use airports, providing pilots direct contact with the controlling facility. Last fall, another 26 approach control facilities covering 226 public-use and 3,000 private-use airports had numbers published in the Chart Supplement, US and subscriber files.

Leidos Flight Service will provide pilots with the name of the facility to contact or the correct phone number to obtain or cancel an IFR clearance. Pilots may continue to request clearances via radio from air traffic control or Flight Service.

You can find the phone numbers for clearance delivery in the remarks section of the entry for each airport in the Chart Supplement, US. This initiative does not affect pilots requesting clearances from Flight Service over Remote Communications Outlets (RCO), Ground Communication Outlets (GCO), or from locations in Alaska.
