Section III - SYSTEMS DESCRIPTION
AUXILIARY SYSTEM
The auxiliary hydraulic system provides an alternative source of hydraulic power for landing gear
lowering and flaps operation. The system is hand-operated, and when selected, is independent of the
main system.
The following notes must be observed:
NOTES:
1. Emergency lowering of the landing gear is available regardless of the setting of the
landing gear selector lever but the flaps must be selected to the required setting.
2. When using the auxiliary system, lowering of the landing gear always occurs before
operation of the flaps.
3. The system cannot be used to raise the landing gear.
4. Following the selection of the auxiliary system, it must be reset manually before the
main system can be used to operate the landing gear.
CAUTION:
IF A SELECTION OF THE AUXILIARY SYSTEM HAS BEEN MADE FOLLOWING A MAIN
SYSTEM FAILURE, THE AUXILIARY SYSTEM MUST NOT BE RESET IN FLIGHT. IGNORING
THIS CAUTION COULD RESULT IN THE LANDING GEAR COLLAPSING ON TOUCHDOWN.
