2B1 EP's Flashcards
GOV light (amber)
- Avoid abrupt power variations
- IAS… Maintain below Vne Power off
- Land as soon as practicable
ENG P light
- Power… Reduce
If engine oil pressure is low or zero:
- Autorotate / Engine Shutdown
If engine oil pressure is normal:
- Land as soon as possible
GOV light (red)
- Flight Parameters… Check
- Maintain Ng > 80% with PA < 20,000 ft
- Land as soon as practicable
MGB P light
- Power… Reduce
2. Land as soon as possible
SERVO light - in flight
Land as soon as practicable
Tail Rotor Control Failure (Fixed Pedal)
