7.2 Keypad Display
7.2.1 F1 - F4
These function keys or soft-keys are used to select choices from menus. The menu choices
may be shown directly over the keys or displayed as a list. When a menu is displayed, press
the appropriate function key to select the required choice.
CLEAR /QUIT
can be used to leave
a menu without making a selection.
7.2.2 ALT/Ps
1.
In aeronautical units (ft or m), this key selects an altitude display.
2.
In pressure units (mbar, inHg etc.), this key selects a static pressure (Ps) display.
3.
SETUP
, [UNITS] can be used to change the units of display, if setup mode is not
switched off.
4.
Before entering a new altitude or Ps aim, set the rate of change using the
ROC/Ps
RATE
key.
5.
In Control Mode (Aim display), enter a new altitude or Ps aim using the numeric keys.
Use
LEAK MEASURE/CONTROL
to exchange between control and measure mode.
7.2.3 SPEED/Qc
1.
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).
2.
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).
3.
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 setup mode.
4.
Use
SETUP, SPEED/Qc
, [CAS/TAS] to select CAS or TAS.
5.
CAS/TAS can be changed in full setup mode.
6.
If the altitude aim is changed, after the entry of CAS, the Mach and TAS aim values
change while the CAS value remains unchanged
*
.
7.
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
*
.
8.
If the Ps aim is changed, after the entry of Qc, then the Pt aim value changes while the
Qc remains unchanged
*
.
*
The display shows = symbol next to the parameter that remains unchanged.
