Three sets of three calibration parameters are necessary to correct for the influence
of the aircraft itself on air-data measurements (e.g. pitot-static pressure, angle of
sideslip, and angle of attack). These parameters are obtained by analysis of flight
data obtained during special calibration maneuvers (see Section 3.3) and will be
provided to the end user by Aventech Research Inc.
The dynamic heating efficiency parameter should always be set to 0.42 as this is a
function of the air-data probe design and not subject to change.
Although magnetic sensor data is no longer utilized by the CPM firmware, these
calibration factors have been included for backwards compatibility.
Once the new values have been entered into the window, click OK to upload and
program these settings into the CPM Data FLASH. The new parameters will take
effect on the next power cycle of the instrumentation.
4.7 Cross-Axis Alignment Errors
The “Cross-Axis” menu item displays a window which allows the user to enter and
program the cross-axis alignment errors.
