Note: Rate-Target values entered in Air-Data units (altitude and airspeed units) are maintained
separately from Rate-Target values entered in pressure units (inHg, mbar, etc.). When operating in
Air-Data units, the air-data rates are effective. When operating in pressure units, the pressure rates are
effective. However, the Static pressure rate is internally limited by the altitude rate and never allowed
to exceed it.
Pitot Rate Target value
The Pitot Rate Target value can be changed only if the key# symbol (3) is displayed to the left of the Pitot
Rate Target value field. Press key '3' on the keypad and the Lower section of the display will appear as
shown in Figure 3.11 below.
Figure 3.11 : Pitot Rate Target value
Use the keypad to enter the desired value in the field shown. To clear an entry, press CLR. To accept the
entry, press ENTER. To exit this screen without changing the Rate Target value, press CANC. If the
number of digits entered (either before or after the decimal) exceeds the maximum allowed for the
current units, a long beep will be heard.
If the entered value exceeds the programmed limits, the following message will appear.
Pitot Rate target exceeds limit. Press CLR
Note: When Pitot is in pressure units, the Pitot Rate target is internally set to be equal to the Static
Rate target while the Static output is ramping. Once the Static output stops ramping, the commanded
Pitot Rate target becomes effective.
Note: In pressure units, Pitot-Rate targets can be set between 0 and 30 inHg/min.
If the Rate Target value needs to be changed in small increments, instead of entering a value, the arrow
keys may be used to Jog the Rate Target value up or down. If the current Pitot Rate Target value is 150.0
knots, and the Lower screen appears as in Figure 3.11 above, pressing the Up-Arrow key will make the
screen appear as shown in Figure 3.12 below.
