Definition
The angular position of the power lever in a turbine engine control system, measured from the idle stop, that signals the engine's fuel control unit how much thrust or power the pilot is requesting.
Plain English
How far forward the throttle lever is pushed, expressed as an angle. The fuel control reads that angle and gives the engine the matching amount of fuel.
Context Anchor
Seen in turbine-engine aircraft, engine control descriptions, maintenance data, and troubleshooting procedures.
Derivation
Straightforward: the 'power lever' is the turbine equivalent of a throttle, and 'angle' refers to its rotational position. The term names exactly what it measures — the angle of the power lever.
Why Pilots Care
Directly controls thrust output and must be set precisely for safe takeoff, climb, cruise, and landing performance.
Intuition Check
Do not read this as an angle of the airplane in level flight. Here, it means the measured position of the power control lever.
Example Sentence 1
The fuel control unit uses power level angle as one of its main inputs when scheduling fuel flow to the engine.
Example Sentence 2
In cruise the power level angle was reduced to 35 degrees to maintain economical fuel flow.
