ALT/Ps
In aeronautical units (ft or m), this key selects an altitude display.
In pressure units (mbar, inHg etc.), this key selects a static pressure (Ps) display.
SETUP, [UNITS] can be used to change the units of display, if set-up mode is not switched off.
Before entering a new altitude or Ps aim, set the rate of change using the ROC/Ps Rate
key.
In Control Mode (Aim display), enter a new altitude or Ps aim using the numeric keys.
Use LEAK MEASURE/CONTROL to change between Control and Leak Measure mode.
SPEED/Qc
In aeronautical units (kts, km/h), this key selects an airspeed (CAS or TAS) display. In
pressure units (mbar, inHg etc.), this key selects dynamic pressure and the display
shows (Qc).
The airspeed can be displayed and entered as either Calibrated Airspeed (CAS, Vc) or
True Airspeed (TAS, Vt).
Note: For testing purposes, Calibrated Airspeed equates to Indicated Airspeed (IAS).
The Pt temperature value affects the calculation of TAS. The value of Pt temperature,
normally measured by the aircraft temperature sensor, can be changed by SETUP,
SPEED/Qc, [Pt TEMPERATURE] only in full set-up mode.
Use SETUP, SPEED/Qc, [CAS/TAS] to select CAS or TAS.
CAS/TAS can be changed in full set-up mode.
If the altitude aim is changed, after the entry of CAS, the Mach and TAS aim values
change while the CAS value remains unchanged*.
If the altitude aim is changed, after the entry of TAS or Mach, the CAS aim value
changes while the TAS and Mach values remain unchanged*.
If the Ps aim is changed, after the entry of Qc, then the Pt aim value changes while the
Qc remains unchanged*.
