The General Dynamics X-62 VISTA ("Variable Stability In-flight Simulator Test Aircraft")[2] 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 heavyweight gear permits simulation of aircraft with higher landing sink rates than a standard F-16.
