Some airports have clearance delivery frequencies listed in the chart supplement, but not this one. You try reaching approach control from the ground, but get no response. The ceilings are high enough that you could pick up a clearance in the air, but you don’t dare climb into the Class B shelf above you. Now what?
Formerly, you might contact flight service at 800-WX-BRIEF and have the briefer relay a frequency to you from air traffic control. But that practice is ending, and an increasing number of airports now have a simpler option: Call ATC directly.
The June 20 issue of the chart supplement includes a new batch of phone numbers pilots can use to receive or cancel IFR clearances directly with the appropriate ATC facility. This addition, which includes numbers for 27 approach/departure control facilities and 20 air route traffic control centers, is part of a modernization effort that the FAA says is meant to streamline the process and reduce the risk of error in clearance delivery. Phone numbers have been added to entries for hundreds of public-use airports since the program began in 2017.
This gives pilots three main ways to obtain a clearance at a nontowered airport:
Beginning in October, the chart supplement also will include backup clearance delivery phone numbers for all airports with a remote communications outlet, ground communication outlet, or remote transmitter/receiver to use if the radio communications become unavailable—per AOPA’s request.
