The LGECU combines the status of the aft equipment bay door with the status of the
maintenance hatches to produce a single EICAS indication.
The maintenance hatches that are monitored are:
• Rear hydraulic system access door
• Refuel/defuel station door
• Optional belly fairing storage access door
Aft Equipment Bay
An electrical proximity sensor provides indication to the EICAS system when the door
is properly closed. The LGECU monitors the signals and provides the input to EICAS.
Small Service Doors
The LGECU monitors the signals and provides input to EICAS when any one of the
access/small service doors is not properly closed.

CONTROL WHEEL
The pilot and copilot control wheels contain the following switches:
• Master disconnect
• Pitch Trim Switch
• Autopilot/Flight Director Touch Control Steering Switch
• Radio Key
MASTER DISCONNECT
The Master Disconnect switch disengages the autopilot and deactivates the stick
pusher and the pitch trim. When released, the stick pusher and the pitch trim system
are immediately reactivated but the autopilot remains disengaged.
PITCH TRIM SWITCH
The Pitch Trim Switch enables the pilot/copilot to control the trim from each control
wheel.
AUTOPILOT/FLIGHT DIRECTOR (TOUCH CONTROL STEERING) SWITCH
The Touch Control Steering Switch (TCS) is located on the control wheel. It enables
the pilot to maneuver the airplane without disconnecting the autopilot control.
RADIO KEY
The Radio Key activates the selected radio transmitter.

SYSTEM INTEGRATION
The extensive use of the latest technology for design and operation makes the BD 700
Global one of the most advanced passenger aircraft in the world. Contrary to previous
generation passenger airplanes, which relied on analog technology for system control
and indication, the Global uses computers almost exclusively to monitor all airplane
systems and to provide crew alerting information. This use of computer technology,
with its associated digital data busses and control units, has simplified many of the
traditional flight crew duties and has reduced pilot workload tremendously.
System information that previously came from analog sources, is now provided by a
variety of control units that constantly update and share information. The systems in
the Global have built-in redundancy and provide an added margin of safety for all
operations.
All the airplane systems are designed to self-test on start-up and are continuously selfmonitored
in flight. Should a fault occur, the information is analyzed and compared
with data provided by associated systems before being displayed to the flight crew.
This method of operation ensures that accurate malfunction analysis is made and
appropriate corrective action, by either the flight crew or maintenance personnel, can
be taken.
