Full Definition
The overall capability of an aircraft to produce lift, generate thrust, and overcome drag, expressed through measurable outcomes such as takeoff distance, rate of climb, cruise speed, fuel burn, and service ceiling. Aerodynamic performance depends on air density, aircraft weight, configuration, and engine output, and it changes whenever any of these change.
Context Anchor
Seen when planning takeoff and climb performance, especially in hot , at high- airports, or anytime is a factor.
