Compressor Stall - Turbine Engine

Compressor Stall A Compressor Stall in a gas turbine engine is a condition in an axial-flow compressor in which one or more stages of rotor blades fail to pass air smoothly to the succeeding stages. A stall condition is caused by a pressure ratio that is incompatible with the engine rpm. Compressor ...

Stabilized Approach Concept

A stabilized approach is the safest profile, and it is one of the most critical elements of a safe approach and landing operation. There are five basic elements to the stabilized approach: Landing Configuration - Stabilized Approach Element 1 The airplane should be in the landing configuration early in the approach. The ...

Flight Director - FD

Flight Director Electronic flight calculator that analyzes the navigation selections, signals, and aircraft parameters. It presents steering instructions on the flight display as command bars or crossbars for the pilot to position the nose of the aircraft over or follow. Flight Director Functions A Flight Director is an extremely useful aid that displays ...

Magnus effect

Magnus effect - The Magnus Effect is the lifting force produced when a rotating cylinder produces a pressure differential. This is the same effect that makes a baseball curve or a golf ball slice. When a rotating cylinder or ball is spinning in a fluid, it creates a boundary layer around itself, and ...

Kollsman Window - Altimeter Adjustment - Barometric Pressure Setting Window

Barometric Pressure Setting Window A barometric scale window of a sensitive altimeter used to adjust the altitude for the altimeter setting. The altimeter uses static pressure as its source of operation. Air is denser at sea level than aloft—as altitude increases, atmospheric pressure decreases. This difference in pressure at various levels ...

Maintenance Review Board Report

Maintenance Review Board Report is a document intended for use by air carriers. It contains the initial minimum scheduled maintenance and inspection requirements for a particular transport category aircraft and on-wing engine program. Air carriers use the MRB report and its associated requirements to develop maintenance programs. See AC 121-22A, Maintenance Review Board Procedures, for additional information.
