Definition
Descending circular flight paths flown around a fixed point on the ground, used during a forced or simulated emergency landing to lose altitude while remaining within gliding distance of the chosen landing area.
Plain English
Circles flown downward over your intended landing spot to bleed off extra height without drifting away from the field.
Context Anchor
Used during emergency approach and landing practice when the airplane is high over a selected landing area and the pilot needs to lose altitude while staying close to it.
Derivation
From Latin spira, meaning a coil or twist. The word captures the shape of the flight path: the airplane winds downward in a coil-like pattern around a point on the ground.
Why Pilots Care
Allows rapid, controlled altitude reduction while keeping airspeed within limits and avoiding excessive structural loads during an emergency.
Intuition Check
Do not read spirals here as just any circular motion. In this context, spirals are intentional, controlled descending turns used to manage altitude during an approach.
Example Sentence 1
After the simulated engine failure, the pilot used gentle spirals over the field to lose altitude before turning onto final.
Example Sentence 2
In the simulated engine-out exercise, spirals were used to stay close to the airport while bleeding off altitude.
