TARGET VALUE KEYS :
There are typically 4 parameters that the 6600 controls - Airspeed (or Pt pressure), Altitude
(or Ps1 pressure), Climb (or Pt, Ps1, Ps2 rate) and Secondary Altitude (or Ps2 pressure). Each
parameter can be changed using a specific target-value key.
The Pt /AIRSPEED key is used to select Pt or Airspeed target value.
The Ps2/RATE key is used to select Ps2 target value if the Main screen being displayed is in
the 3-output format (section 3.2). If the Main screen being displayed is in the 2-output format
then this key is used to select the target value for Rate of change of Ps1, in Ps1 units per
minute (i.e. feet/min, meters/min, inHg/min or mbar/min).
The rate of change of Ps1 is also used as the rate of change of Ps2, and in units of inHg and
mbar, is also used as the rate of change of Pt. For more details please see "Effects of Rate
target value" in section 3.2.2.
The Ps1/ALTITUDE key is used to select Ps1 or Altitude target value.
After selecting the target value key, the new value can be entered using the numeric keypad.
The UP ARROW and DOWN ARROW keys are used to "Jog" a target value. For more
information, please refer to Section 3.2.2. The arrow keys are also used to move between
various choices during Unit selection and Mode selection.
The HOLD key is used to hold the current pressure on all three outputs. Pressing the HOLD
key again will allow pressure to continue to ramp towards the desired target.

Units can be selected independently for the Pt, Ps1 and Ps2 outputs.
