ForeFlight’s Call Sign program allows you to receive a unique “FFL” identifier with which you can file flight plans in place of your aircraft's tail number. ForeFlight call signs are available for all ForeFlight Performance customers, regardless of what type of aircraft you fly.
There are numerous benefits to filing with a call sign based on your particular situation, including:
Filing with a call sign is an easy way to add a layer of privacy that would not be possible when filing with your tail number. Using a call sign prevents others from seeing your aircraft’s actual registration as part of your ADS-B Out transmission, and also prevents anyone from easily finding your aircraft using flight tracking services like FlightAware. And if you have blocked your aircraft's tail number at the FAA level, a call sign allows you to still track your flights using those services, while making them difficult to track for others.
Compliance with FAA’s PIA Program
For those seeking maximum privacy from flight tracking, the FAA’s Privacy ICAO Address (PIA) program offers a solution. Filing with a call sign hides your aircraft’s registration, but it doesn’t hide your aircraft’s fixed ADS-B ICAO address, which is tied to your aircraft’s registration and could thus be used to track your flights. The PIA program allows you to change your aircraft’s ICAO address to one associated only with the call sign, severing the link to your aircraft's actual registration. Learn more about PIA and the requirements to enter the program here.
Flexible PDC Delivery
Registering for Pre-Departure Clearance (PDC) through ForeFlight using your aircraft’s tail number imposes certain restrictions, including limiting your use of PDC to only that aircraft and preventing anyone other than yourself (or other pilots on the same multi-pilot account) from filing flight plans with that aircraft. These restrictions are not tenable for someone who flies aircraft used by others (such as rentals), or who wants to use PDC with multiple aircraft. Registering for PDC using a call sign avoids both of these issues, allowing you to file with the call sign and receive your PDC for multiple aircraft and for aircraft flown by others. Like ForeFlight call signs, PDC is available for all Performance customers at no additional charge. Learn more about PDC through ForeFlight here.
ForeFlight Call Signs are available at no additional cost with all ForeFlight Performance plans.
