If the unit of measure selected is a true airspeed (unit label in upper case, e.g. KTS), the
temperature used in airspeed calculation must be specified. When the unit is selected, the
display is:
1. Entry field for temperature to be used in true airspeed
calculation.
True airspeed temp:
15.0 ºC
Enter the desired temperature value. The default value for true airspeed air temperature is
set in
[SPECIAL] , <6Punit> when the unit is set up (see Section 3.5.6).
In RPM4-AD displays, calibrated airspeed units are represented in lower case (e.g. kts)
and true airspeed units are represented in upper case (e.g. KTS).

The pressure unit of measure selected is Q-RPT and measurement mode specific. For that
Q-RPT and measurement mode, all functions and settings are represented in the current
unit of measure for that range. However, certain internal and/or metrological functions
(e.g., Q-RPT calibration coefficients) are always represented in Pa regardless of the current
unit selection.
