Definition
Flight conducted solely by reference to flight instruments, without any outside visual reference to the ground, horizon, or other visual cues. An older term, largely replaced in modern usage by 'instrument flight.'
Plain English
Flying when you can't see anything outside the aircraft, so you control the plane entirely by reading your instruments.
Context Anchor
Seen in older aviation texts and in discussions of instrument flying, especially when clouds, darkness, or training conditions remove the pilot’s view outside.
Derivation
Called 'blind' because the pilot is effectively without sight of the outside world — flying through cloud, fog, or darkness — and must rely entirely on the instrument panel to know the aircraft's attitude, altitude, and direction.
Why Pilots Care
Enables continued safe flight and orientation when clouds, darkness, or haze remove visual cues, directly reducing risk of spatial disorientation.
Intuition Check
Do not read “blind flight” as a pilot flying with no sight. It means the outside view is unavailable or unreliable, so the pilot must fly by instruments.
Example Sentence 1
Early airmail pilots developed blind flight techniques so they could continue their routes through fog and night weather.
Example Sentence 2
Instrument students practice blind flight under the hood to build the skills needed for real instrument meteorological conditions.
