1.3 Abbreviations and definitions
CAS Calibrated airspeed. It is IAS corrected by errors due to
instrument and pitot port errors. CAS is equivalent to the true
airspeed at zero level of international standard atmosphere.
IAS
Indicated airspeed. It is the reading of the in-built airspeed
indicator corrected by the instrument error.
TAS
True airspeed. It is the aircraft velocity considering
“undisturbed” air.
IFR Instrument flight rules.
VFR Visual flight rules.
ISA
International standard atmosphere.
MAC Mean aerodynamic chord.
VTU Vertical tail unit (fin with rudder).
HTU Horizontal tail unit (stabilizer with elevator).
V
A
Designed manoeuvring velocity.
V
SO
Stalling velocity in landing configuration.
V
S1
Stalling velocity with flaps up.
V
NE
Never exceed velocity.
V
FE
Maximum velocity with flaps fully extended
V
F0
Maximum velocity for flap extending and retracting.
RWY Runway
