Proposal Title: C-21 Avionics Upgrade Requirements Document Branch of Service: Air Force

Objective The C-21A is derived from a commercial Learjet 35A and modified to supply passenger, medical evacuation and cargo airlift support for military operations. A total of 19 aircraft are located both in USA and at overseas locations requiring unrestricted flight operations in worldwide airspace. The C-21 Avionics Suite has become obsolete, unsupportable and does not meet minimum FAA mandated regulations. A current Avionics Suite is needed to meet minimum FAA mandated regulations to continue to fly current missions. The upgrades shall be capable of worldwide flight operations at all times in all civil and military airspace including known future CNS/ATM (Communication Navigation Surveillance/ Air Traffic Management) requirements through the 2030 timeframe. Learjet, Inc. and/or its subcontractors retain all rights to commercial OEM data.
