AOA Angle of Attack. Incidence of the aerodynamic chord
in relation to the still air.
Climb Gradient Climb Gradient Climb Gradient Climb Gradient
The ratio of the change in altitude during a portion
of a climb, to the horizontal distance traveled in the
same time interval.
Max. Demonstrated Crosswind Component Max. Demonstrated Crosswind Component Max. Demonstrated Crosswind Component Max. Demonstrated Crosswind Component
The demonstrated crosswind component for which
adequate control of the airplane during take-off and
landing was actually demonstrated. The value is
