ACA: Change Coming To Use of Compassion Call Sign
New procedure will comply with changes to ICAO and FAA call sign requirements, Air Care Alliance says.

Changes to ICAO and FAA call sign requirements are prompting a new procedure for pilots using the compassion call sign and CMF identifier on public benefit flights, the Air Care Alliance (ACA) announced this week. Effective December 15, the new procedure requires pilots of authorized volunteer pilot groups using the call sign to register for a discrete compassion call sign through the ACA website instead of the previous filing procedure using a portion of the pilot’s aircraft registration number.
