basic flight Procedures

downwash

a. the change in the direction of air deflected by the aerodynamic action of an airfoil, wing or helicopter rotor blade in motion, as part of the process of producing lift 

angle of attack

b. the angle of the wing chord in relation to the free stream airflow as it moves forward through the air 

pitch

c. the rotation of an airplane around its lateral axis

rotation

d. a maneuver conducted during the takeoff ground roll 

flare

e. the nose-up landing posture normal for most land-based aircraft 

decompression

f. the loss of internal aircraft air pressure 

circuit pattern

j. a standard path followed by aircraft when taking off or landing while maintaining visual contact with the airfield

stall

h. a flight condition during which lift is destroyed due to low airplane speed or attitude 

touchdown

i. the point at which an aircraft first makes contact with the runway  

decompression

f. the loss of internal aircraft air pressure
