Study Notes
Landing Gear System
- Airplane equipped with retractable, tricycle air-oil strut type landing gear, hydraulically operated.
- Operation powered by an electrically reversible pump.
- Gear position indications:
- Three green lights for gear down and locked.
- One red light at the top of the instrument panel for unsafe gear position.
Gear Retraction and Locking
- No indication light for fully retracted gear; all lights must be off.
- Downlock hooks engage as the landing gear swings to the down and locked position.
- Activation of individual downlock switches triggers green lights, confirming gear is down and locked.
- All three downlock switches' activation turns off the hydraulic pump.
Light Visibility Adjustments
- Green landing gear lights automatically dim if NAV LIGHTS switch is ON during the daytime.
- In aircraft without a DAY/NIGHT switch, visibility of gear lights may be poor.
- DAY/NIGHT switch must be in DAY position during daytime for clear visibility of gear lights.
Gear Unsafe Indication
- During gear retraction, down limit switches engage, allowing the gear unsafe light to illuminate.
- Gear unsafe light remains active until the gear is fully retracted and up limit switches are engaged, indicating a shift to their normally open (NO) circuit.
