Definition
A training procedure in a multi-engine airplane in which the instructor sets the propeller of an inoperative-engine simulation to a low-drag, high-pitch position that approximates a feathered propeller, without actually feathering it. This allows the student to practice engine-out procedures while keeping the engine available for immediate restoration of normal power.
Plain English
A practice setup where the instructor pretends an engine has been shut down and the propeller has been streamlined into the wind, but the engine is actually still running at low power. It lets the student practice engine-out flying without really shutting anything down.
Context Anchor
Used during multiengine training when practicing engine-failure procedures without actually feathering a propeller in flight.
Derivation
To 'feather' a propeller means to rotate its blades so they point edge-first into the relative wind, producing minimum drag when the engine is shut down. 'Simulated' means the condition is approximated for training rather than actually performed. Together: an approximation of a feathered propeller for training purposes.
Why Pilots Care
Enables realistic practice of asymmetric thrust, control inputs, and performance without the risks of a real engine shutdown.
Intuition Check
Do not read “simulated” as fake or unimportant. In this context, the engine is still running, but the airplane is being set up to feel and perform like it would with a feathered propeller.
Example Sentence 1
During the multi-engine checkride, the examiner called for a simulated feather on the right engine and asked the applicant to demonstrate single-engine climb performance.
Example Sentence 2
After identifying the simulated failure, the pilot set the propeller control to the simulated feather position before securing the engine.
