Landing Gear Retraction Systems
Landing Gear Retraction Systems
• Cessna 182 RG
• Hydraulically actuators powered by an electrically-driven hydraulic power pack.
• Normal operating pressure of 1000 PSI to 1500 PSI.
• Provides a positive up lock pressure on the main landing gear.
• Nose gear uses an over-center mechanical linkage.
Landing Gear Retraction Systems
• Cessna 182 Gear Warning Horn
• Based on the position of the throttle (power reduction to ~15 inches manifold pressure).
• Also requires the gear to be NOT down and locked (no green light).
• Not driven by speed.
• Not driven by altitude.
Aircraft Brakes
Wheel Units
• Energizing-type Drum Brake
• Weight of the vehicle or aircraft aids in the application of the brake.
Wheel Units
• Nonenergizing Brakes
• Expander Tube
• Disc Brakes
Disc Brakes
• Single Disc
• Most popular brake for modern light aircraft.
• Multiple Disc
Goodyear Single Disc (Keyed)
Brake Energizing Systems
• Diaphragm Type Master Cylinder
• Vented Master cylinders
• Boosted Brake Master Cylinders
• Power Brake System
