5.4 AIRSPEED CALIBRATION
The airspeed calibration chart (see Fig. 5-5) is provided to determine Calibrated Airspeed
(CAS) from Indicated Airspeed (IAS) using the pitot static system installation-error correc-
tion for level flight.
NOTE Indicated airspeed assumes zero instrument error.
The corrections apply for all practical altitudes and gross masses, and with the helicopter
flown with no appreciable yaw.
EXAMPLE
: (see Fig. 5-5)
Determine: Calibrated airspeed (CAS), level flight
Known: Indicated airspeed 90 KIAS
Solution: 1. Enter chart at known indicated airspeed (90 KIAS).
2. Move vertically up to LEVEL FLIGHT line.
3. Move horizontally left and read calibrated airspeed = 91 KCAS
