Flight Control Panel
The Flight Control Panel additional information module will cover the function of switches
and lights on the Flight Control Panel specifically and primary flight controls in general.
Flight controls are discussed in the Hydraulic System Module.
Crew control of the standby hydraulic pump is available from this panel through use of the
A and B FLT CONTROL switches and Alternate Flaps master switch, however activation of
the standby system and standby hydraulic pump is largely an automatic function as follows:
Automatic operation is initiated when the following conditions exist:
- Loss of system A or B, and
- flaps extended, and
- airborne, or wheel speed greater than 60 kts, and
- FLT CONTROL switch A or B Hydraulic System ON.
FLT CONTROL switches A and B
Standby Rudder On
The standby rudder PCU is powered by the standby hydraulic system. The standby
hydraulic system is provided as a backup if system A and/or B pressure is lost. With the
standby rudder PCU powered the pilot retains adequate rudder control capability. It can be
operated manually through the FLT CONTROL switches or automatically. An amber STBY
RUD ON light illuminates when the standby rudder hydraulic system is pressurized. The
standby rudder system can be pressurized with either Flight Control switch, automatically
during takeoff or landing or automatically by the Force Fight Monitor. The STBY RUD ON
light illumination activates Master Caution and Flight Control warning lights on the Systems
Annunciation Panel.
