The pilot FUEL GAGE TEST switch is used to test the fuel quantity indicator operation. Pressing the switch causes the indicator pointer to move from the actual reading to a lesser reading. Releasing the switch will cause the pointer to return to the actual reading. The circuit is powered by the ac system and protected by the FUEL QTY circuit breaker.
The emergency hydraulic system serves two functions. It provides hydraulic power to the turret and outboard pylons for boresighting, or to the collective pitch control if both hydraulic systems fail. The system is controlled by the EMER HYDR PUMP switch powered by the dc essential bus and protected by the EMER HYD PUMP circuit breaker.
