respective engine (pedestal panel Shift-6) and engine start will be
completed.
Opening fuel at 20% should result in a smooth engine start. The
starter will automatically close at 45% N2.
Now engine 1 can be started using the same procedure. In fact the
APU or the external air source can now be turned off as bleed air can
be used from engine 2 for starting engine 1.

MAXIMUM AND OPTIMUM
CRUISE LEVEL
The “Status” page of the set-up panel shows the optimum and
maximum cruising level for the current gross weight and selected
Mach cruising speed.
Figure 14: Set-up panel „Status“ page
The top line of the status page shows the current gross weight (in
pounds), the optimum and maximum cruising levels for either M.78,
M.80 and M.82 cruising speed, the current hydraulic fluid levels for
the Green, the Blue and the Yellow system and the present cabin
altitude.

Autoflight System: Autopilot
and Autothrottle
Figure 15: Automatic flight control system
Finally a word on the autoflight system. This system is somewhat
different from the standard Boeing and Airbus autopilots that you are
probably used to.
The A300 has 2 autopilots (AP) and two flight directors (FD’s). In fact
the FD’s are the primary instruments that provide information to the
autopilots. The active autopilot mode can only be read from the failure
and performance indicator (FPI).
Figure 16: FPI
GENERAL
The AP cannot be engaged while on the ground, the FD’s can be
however, and the FD bars will already show on the ground. Since the
AP uses electricity, the automatic pitch trim system, the yaw dampers
and the hydraulic systems, you have to make sure all of these are
available (at least 1 yaw damper and 1 pitch trim needs to be engaged)
before you can engage the AP.
To engage the auto-throttle (A/T) for take-off, the N1 computer has to
be selected to Take Off (TO) or Flex Take Off (FLX TO) mode.

Figure 17: N1 Computer with TO and FLX TO mode selected
On the ground only N1 A/T mode is available, once airborne both N1
and Speed mode are available.
Note: The Master warning panel includes a hidden click zone to turn
off the THR OFF warning lights.

HIDDEN CLICK ZONES ON AFCS PANEL
The autopilot can be controlled by the mouse and each settings can be
changed by clicking either the left or the right mouse button changing
the selected field by either +/- 1/100 or +/- 10/1000.
