ASI
Airspeed Indicator
TAS
True Airspeed
The speed of the aircraft in relation to the air mass in which it is flying.
IAS
Indicated Airspeed
Uncorrected as indicated by ASI.
CAS
Calibrated Airspeed
ASI corrected for instrument errors.
EAS
Equivalent Airspeed
ASI corrected for adiabatic compressible flow for the particular altitude.
Side effect of pitot tube errors in non-standard atmospheric pressures.
VS<span>0</span>
Stall speed in landing configuration (flaps down.)
VS1
Stall speed with flaps up.
VY
Speed for maximum altitude per unit of time.
Best rate-of-climb.
VX
Speed for maximum altitude per unit of distance.
Best angle-of-climb.
VLE
Max speed with landing gear extended.
VL0
Max speed to lower landing gear.
VFE
Max speed with flaps extended.
VA
The calibrated design maneuvering speed.
Max speed for full Application of flight controls.
VN0
Max Cruising speed.
VNE
Never exceed speed.
May cause structural damage.
OAT
Outside Air Temperature.
PA
Pressure Altitude.
Set the altimeter to the current barometric pressure and read the pressure altitude.
Density Altitude
Pressure altitude corrected for non-standard temperatures and altitudes.
Need charts or conversion calculator.
VS
Stall speed.
