Once these actions are completed, the pilots must carry out an
instrument crosscheck as follows:
- Both AIRSPEED TAPES not showing speed;
- EADI’s level and flag-free;
- Both ALTIMETERS with their QNH set, and reading
consistent altitudes;
- Both VERTICAL SPEED INDICATORS showing zero;
- EHSI’s with the courses selected according to the intended
departure procedure, showing the same magnetic heading,
flag-free and with the heading bug set to the intended
runway heading;
- If the crew already has obtained predeparture clearance,
they can select the initial assigned altitude on the ASEL; if
the clearance is not available yet, the requested altitude
minus 100 ft or yet the most probable altitude can be set
;
-
The 100 ft decrement is a reminder that the selected
altitude has not been authorized by ATC yet.
Standby Instruments..................................................... SET
Set the QNH or QFE on the standby altimeter.
RMU.............................................................................. SET
The PF assigned for the flight must select the applicable COMM
and NAV frequencies for the intended departure and select ABOVE
and a proper range on the TCAS. Also, the PF should change the
Flight Number. If necessary.
Stall Protection System................................................. CHECKED
The AHRS/IRS should be aligned.
CUTOUT 1 and 2 buttons must be guarded and not illuminated and
QUICK DISCONNECT BUTTON must be released.
Carry out the Stall Protection System test as follows:
- Pull the control column all the way back and momentarily
press the SPS TEST button (the TEST button must not be
kept pressed beyond the shaker actuation). Both the stick
shaker and the stick pusher will actuate and an aural
warning will be heard.
- Lightly counteract the control column tendency to move
forward.
- The test takes about 5 seconds and is valid if the amber
light on the TEST button extinguishes.
