1.9 TERMINOLOGY
Air Speeds
CAS Calibrated Air Speed. CAS is the same as TAS
(True Air Speed) in std. atmospheric condition at sea level
KCAS Calibrated speed in knots
GS Ground speed
IAS Indicated air speed
KIAS Indicated speed in knots
TAS True air speed. It's the same as CAS compensated for
altitude, temperature and density
VA Maneuvering speed
VNE Never exceed speed
VNO Maximum structural crusing speed
VS Stalling speed or minimum steady flight speed
VX Best angle-of-climb speed
