Plain English Meaning

Full Definition
A fixed visual feature outside the airplane — such as a point on the horizon, a distant landmark, or a spot on the windshield aligned with the natural horizon — that the pilot uses as a steady visual cue to maintain a desired pitch attitude, heading, or bank during flight by outside reference.
Context Anchor
Used while looking outside the airplane during basic flight maneuvers, especially when learning to hold straight-and-level flight by sight.
