Gideslope deviation (via IAC)

The COM and MON channels use the following sensors:

The IAC busses provide the following:
.  
General airplane configuration . Pilot and Copilot sensor selection, navigation/FMS data and airplane parameters (speed, system status, AP/FD/AT modes).

.  
Radio information and data integrity, such as VOR/ILS, DME and ADF.

HEAD-UP DISPLAY SYSTEM (HUD) (CONT'D)
Optical Projector Unit
The Optical Projector Unit draws an image on the screen of a cathode ray tube (CRT) and this image is projected through a relay lens to the separate Combiner Unit.
The Optical Projector Unit is fitted with:
.
Optical lens assembly

.
Display circuits

.
Internal monitoring devices

.
Failure detection devices

.
Combiner Unit position sensor.

NOTE
The Optical Projector Unit is hidden behind the headliner.

FLIGHT INSTRUMENTS
 
HEAD-UP DISPLAY SYSTEM (HUD) (CONT'D)
Combiner Unit
The Combiner Unit superimposes the image drawn by the Optical Projector Unit and is fitted with:
.  
An ambient light detector (photovoltaic cell).

.  
A mirror for position monitoring (enables the position detecting device to verify if the Combiner Unit is in the correct position).

.  
A stowage and breakaway system.

The Combiner can be selected in three different positions:
.  
Stowed position, when the HUD is not being used.

.  
Operational position, to allow symbology display.

.  
A crash position, in the event of an emergency.

HEAD-UP DISPLAY SYSTEM (HUD) (CONT'D)
Combiner Unit Folding/Unfolding
The Combiner Unit folding/unfolding operation shall extend the combiner to operate and stow after use. The image should be available within two seconds of deployement if the system is powered-up (the power-up sequence is approximately one minute).
A handle, on the right side of the arm, folds or unfolds the Combiner Unit and locks it mechanically when in the operational or stowed position.
To lock, turn the handle clockwise. To unlock, turn the handle counterclockwise.
NOTE
If the Combiner Unit is accidentally moved into the crash position, the unit is locked in place. A reset button located to the left of the Combiner Unit must be pushed in to allow the return to the operational position.

Operational Position Lock Marks

CAUTION
A "click" must be heard at locking, otherwise, the Combiner Unit is not locked.
