using the Engine Start Lever. Also both squibs on each fire extinguisher are armed.
b) Closes the Engine Fuel Shutoff Valve. The Spar Fuel Shutoff Valve must be closed
using the Engine Start Lever. Also one squib on each fire extinguisher is armed.
c) Closes both the Spar Fuel Shutoff Valve and the Engine Fuel Shutoff Valve, also one
squib on each fire extinguisher is armed.
d) Closes both the Spar Fuel Shutoff Valve and the Engine Fuel Shutoff Valve, also
both squibs on each fire extinguisher are armed.
c) Closes both the Spar Fuel Shutoff Valve and the Engine Fuel Shutoff Valve, also one
squib on each fire extinguisher is armed.
Placing the TEST switch in the FAULT / INOP position tests…
a) The engine overheat detectors.
b) The fault detection circuits for both engines and the APU.
c) The APU DET INOP light, FAULT light and APU BOTTLE DISCHARGE.
d) The fault detection circuits and loop continuity for both engines and the APU.
b) The fault detection circuits for both engines and the APU.
Pulling the APU fire warning switch up:
a) Discharges the APU fire extinguisher.
b) Trips the APU generator control relay and generator breaker, arms the associated
extinguisher and closes the APU bleed air valve.
c) Closes the fuel shutoff valve and the APU inlet door and allows APU fire warning
switch to be rotated for discharge..
