4.1 Control or Measure Parameter
To change the (displayed) parameter:
a.
Value parameters: Press the parameter key e.g., press SPEED/Qc to display airspeed.
b.
Rate parameter: Press the associated parameter key followed by the rate key for that
channel. e.g, display airspeed rate, press SPEED/Qc then RATE. ROC/Ps Rate may be
directly pressed without first pressing ALT/Ps.
Note: The displayed parameters depend on the last keys pressed.
To display two parameters:
a.
Press each value parameter in turn, e.g., display altitude and airspeed together, press
ALT/Ps then SPEED/Qc.
b.
In control mode, an arrow, at the right-hand end of the aim value, indicates the last
parameter selected. This can be changed by entering a new value.
To display a value parameter together with its rate:
a.
Press the parameter key followed by the associated rate key, e.g, display airspeed and
rate of speed together, press SPEED/Qc then RATE.
Note: If ROC/Ps RATE is pressed, the display automatically shows ALT and ROC.
See Section 7.2.9, "RATE," on page 75 for display details.

parameters (triple).
The triple display always shows altitude and airspeed; with pressure units selected, the
display always shows Ps and either Qc, Pt or EPR. When ALT or CAS are selected the display
