d. Immediately the switch trips, press HOLD. (see Section 7.2.8, “HOLD,” on page 74 for
more details)
e. Read the airspeed value - this is the trip value for increasing airspeed.
f. Enter a new airspeed aim below the expected trip value.
g. Immediately the switch trips, press HOLD.
h. Read the airspeed value - this is the trip value for decreasing airspeed.
i. Press HOLD again to release hold.
7.2.8.2 Example 2 - Start Both Ps and Pt Ramping to New Aims Simultaneously
For both channels to start moving to new aims at the same time, use the following sequence:
a. Press HOLD.
b. Enter Ps channel aim.
c. Enter Pt channel aim.
d. Enter required rates.
e. Press HOLD again to release hold.
f. HOLD is automatically released when entering Measure Mode.
7.2.9 RATE
1. In aeronautical units (kts, km/h), this key selects a rate of change of airspeed (Rate
CAS) display. The following rates are available in aeronautical units:
2. In pressure units (mbar, inHg etc.), this key selects a rate of change of pressure (Rate
Qc, Rate Pt or Rate EPR) display. The actual display depends on the parameter
selected before pressing RATE. The following rates are available in pressure units.
3. If setup mode is not switched off, SETUP, [UNITS] can be used to change the units of
display.
