Oxygen System Fault - Above 10,000 Ft
OXYGEN FAULT Warning
1.
Oxygen Flow Rate.............................................................. CHECK
If no flow:
2.
Initiate Emergency Descent to below 10,000 ft:
a. Power Lever...................................................................... IDLE
b. Mixture............................................................. AS REQUIRED
c. Airspeed ......................................................... VNE (200 KIAS)
If flow is normal:
3. Oxygen Flow Rate.......................................................... MONITOR
4. Initiate Normal Descent as soon as practical
Below 10,000 ft
5. Oxygen System........................................................................OFF
6. Flight ............................................................................ CONTINUE
Remain below altitudes requiring supplemental oxygen.
Amplification
Annunciation indicates tank solenoid failed (open or closed) or flow
rate is low. If flow is checked and confirmed present, solenoid has
failed OPEN; system will continue to provide oxygen until depleted, but
unnecessary flight at altitudes requiring oxygen is not recommended.
