The General Dynamics X-62 VISTA ("Variable Stability In-flight Simulator Test Aircraft") is an experimental aircraft, derived from the F-16D Fighting Falcon, which was modified as a joint venture between General Dynamics and Calspan for use by the United States Air Force (USAF). Originally designated NF-16D, the aircraft was redesignated X-62A in June 2021 as part of an upgrade to a Skyborg, with System for Autonomous Control of Simulation (SACS).
The X-62A remains on the curriculum of the Air Force Test Pilot School as a practice aircraft for test pilots.
