The calibrated airspeed is the indicated airspeed corrected for
the positional and instrumental error. The calibrated airspeed is
equal to the real airspeed in the ISA at the see level.
IAS The indicated airspeed is the airspeed shown on the aircraft
Pitot static speed indicating system with the scale that is
adjusted to include the influence of the adiabatic stream
coercibility at standard atmosphere zero altitude but not
corrected for the speedometer system error.
( ς o/ ς )1/2.
ς o = air specific weight at the see level
ς = air specific gravity at given altitude
