Definition
A descent flown with the wings level, with no bank applied — the aircraft is losing altitude in a straight line rather than in a turn.
Plain English
Going down while flying straight, with the wings flat instead of tilted into a turn.
Context Anchor
Seen in instrument flying discussions of spatial disorientation, especially the graveyard spiral, when a pilot misreads the aircraft’s motion without reliable outside visual references.
Why Pilots Care
In the graveyard spiral illusion, a pilot rolling out of an unnoticed turn may feel they have entered a turn in the opposite direction. If they re-enter the original bank to ‘correct’ that sensation, they end up in a steepening spiral while believing they are in a level descent. Recognising the difference between a true level descent (wings level) and a descending turn (wings banked) is critical to recovery.
Grounding Statement
In this situation, the danger is not the descent alone; it is believing the wings are level when the airplane is actually turning downward.
Intuition Check
Level does not mean holding altitude here. It means the wings seem level, while the airplane is still descending.
Example Sentence 1
Trusting the attitude indicator, the pilot rolled the wings level and established a level descent to break out of the spiral.
Example Sentence 2
Maintaining a level descent on instruments requires close attention to the attitude indicator to keep the wings level.
