Flight testing of the F/A-18E/F automatic carrier landing system

The F/A-18E/F is the U.S. Navy´s premier strike fighter aircraft, manufactured by the Boeing Company. The F/A-18E/F aircraft, while maintaining a high degree of commonality with the F/A-18C/D aircraft, has a lengthened fuselage, larger wing and control surfaces, strengthened landing gear, an improved propulsion system including a growth version of the General Electric F404 engine designated the F414-GE-400, and larger high performance inlets. This paper concentrates on the development, test, and evaluation of the F/A-18E/F Automatic Carrier Landing System (ACLS) up to and including the Third Sea Trials, upon which the aircraft was initially qualified for Mode I, totally automatic, approaches and landings to the aircraft carrier. The paper briefly describes the key components of the F/A-18E/F´s ACLS, including cockpit displays and controls, antennas, autothrottles and flight control implementation, and interface with the shipboard AN/SPN-46(V) ACLS. Test procedures and methodology are presented as well as test results and interpretation. Finally, lessons learned are presented and recommendations are made for future aircraft ACLS developmental test and evaluation efforts
