Military Operations Area (MOA)

Military Operations Area (MOA)

Military Operations Area (MOA) – Airspace established outside positive control area to separate/segregate certain nonhazardous military activities from IFR traffic and to identify for VFR traffic where these activities are conducted.
MOA’s are established to contain certain military activities such as air combat maneuvers, air intercepts, acrobatics, etc
From the FAA AIM:

MOAs consist of airspace of defined vertical [...]

Transponder Codes

Transponder Codes

 
Transponder Codes are one of 4,096 four-digit discrete codes ATC assigns to distinguish between aircraft. 
Emergency Transponder Codes are set by pilots as follows: 
Code 7500 (hijack code) 
 Code 7600 (loss of radio communications code)

Compressor Stall - Turbine Engine

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 stall will be indicated by a [...]

CDI - Course Deviation Indicator

CDI – Course Deviation Indicator

 
 CDI – Course Deviation Indicator
A Navigation Instrument that indicates the course and direction to a tuned VOR station
It consists of (1) omnibearing selector (OBS) sometimes referred to as the course selector, (2) a CDI needle (Left-Right Needle), and (3) a TO/FROM indicator. The course selector is an azimuth dial that can be rotated to select a [...]

Compass Rose - Aircraft Compass Swing

Compass Rose – Aircraft Compass Swing

Compass Rose – A small circle graduated in 360  increments, to show direction expressed in degrees.
Most airports have a compass rose, which is a series of lines marked out on a ramp or maintenance run up area where there is no magnetic interference. Lines, oriented to magnetic north, are painted every 30° which is used [...]

Kollsman Window - Altimeter Adjustment - Barometric Pressure Setting Window

Kollsman Window – Altimeter Adjustment – Barometric Pressure Setting Window

Kollsman Window – Altimeter – Paul Kollsman invented the first accurate Barometric Altimeter wiith an accuracy of a few feet. Prior to Kollsman’s invention, altimeters could only determine an airplane’s altitude within a few hundred feet. Kollsman’s invention was used on the first “Blind Flight” conducted by James “Jimmy” Doolittle proving the ability to fly using only instruments.

Region of Reverse / Reversed Command

Region of Reverse / Reversed Command

Region of Reverse Command
Flight regime in which flight at a higher airspeed requires a lower power setting and a lower airspeed requires a higher power setting in order to maintain altitude. 
Aerodynamic Properties of the Aircraft
The aerodynamic properties of an aircraft generally determine the power requirements at various conditions of flight, while the powerplant capabilities generally determine the [...]

Accelerate-stop distance

Accelerate-stop distance

Accelerated Stop Distance is the distance required to accelerate to V1 with all engines at takeoff power, experience an engine failure at V1, and abort the takeoff and bring the airplane to a stop using braking action only and not reverse thrust. Here is a video undergoing an Accelerate Stop Test during certification
