Absolute Altitude – The vertical distance between the aircraft and ground level.Ībsolute Ceiling – The highest altitude an aircraft can fly at maximum throttle while maintaining level height and constant airspeed.Īccelerated Stall – A stall that occurs at a higher airspeed than a normal stall due to a higher load factor (g).Īdverse yaw – Occurs when the plane’s nose turns away from the direction of turn.ĪDF (Automatic Direction Finder) – A navigation system that identifies the relative bearing of an aircraft based on a radio beacon transmitting in the MF or LF bandwidth.Īdiabatic Lapse Rate – The rate at which temperature changes due to increasing and decreasing altitude, under conditions of thermal equilibrium.Īdverse Yaw – When an aircraft turns in the opposite direction of a roll due to use of ailerons and the difference in lift and drag of each wing.Īeronautical Decision-Making – Training and planning to make the best and safest decisions to mitigate risk.Īeronautical Information Manual (AIM) – An official Federal Aviation Administration (FAA) publication that details proper pilot operation within the US National Airspace System, including Air Traffic Control (ATC) and aviation safety.ĪGL – (Above Ground Level) – The vertical distance measured between the aircraft and a specific land mass.Īileron – The movable, hinged flight control surfaces that are used in pairs with opposite motions to control the roll of an aircraft.
