First ASIO Special Missions Citation CJ3 Textron/Cessna has delivered numerous Citation CJ family jets over the years but this instance of a CJ3 AISO Special Missions handover is a first for Textron Aviation. AISO is the abbreviated version for Airborne Surveillance, Intelligence, and Observation. Technically it isn't Textron who did the conversion it is a company called Bird Aerosystems. The aircraft will be used two-fold, for Special Missions as well as VIP roles. This is where a supplemental type certificate (STC) awarded by Civil Aviation Authority of Israel to Bird Aerosystems is important. The STC allows for the cabin configurations to be changed without the need to dismantle ASIO sensors and systems, which then improves the efficiency of the dual role the aircraft is expected to play.
