Some pilots and operators will have another series of preflight checks to conduct when the ADS-B mandate kicks in on Jan. 1. The FAA says in a new policy statement it will be up to pilots and operators to make sure the gear will actually work along their predicted flight path. As part of the flight planning process, operators will be required to exercise “due diligence” in the form of a “preflight availability prediction” to make sure that an adequate GPS signal is available for the ADS-B Out to function properly for the full flight.
