Plain English Meaning

A wearable headset puts you inside a computer-made world that looks and reacts like a real one. In flight training, that world can be a cockpit, an airport, or a flight in bad weather, used so you can practice without leaving the ground.

Full Definition

A computer-generated, three-dimensional environment that a user experiences through a headset and, in some systems, hand controllers or motion sensors. The environment responds to head and body movement, allowing the user to look around and interact as if physically present. In aviation training, VR is used to simulate cockpits, airports, weather conditions, and flight scenarios for instructional purposes.
