Yaw Braking
Yaw Braking refers to the use of differential braking on an aircraft's main landing gear to assist with directional control during ground operations. This technique is especially useful for sharp turns, taxiing in strong crosswinds, or when rudder/nose-wheel steering authority is limited.
How Yaw Braking Works
In many aircraft with toe brakes, the rudder pedals are designed to control both yaw and braking. Pressing the top portion of the rudder pedal applies braking force to the respective main wheel. Applying asymmetric brake pressure creates a yawing moment that turns the aircraft.
Yaw braking is especially useful when:
- The aircraft lacks nose-wheel steering (common in some light aircraft)
- Airspeed is too low for aerodynamic rudder effectiveness
- Tight taxiway or ramp maneuvering is required
Applications
- Taxiing: Provides turning capability for aircraft with limited steering authority.
- Crosswind Operations: Helps maintain ground control during taxiing in crosswinds.
- Engine-Out Scenarios: Supplements yaw control when asymmetric thrust is present.
- Landing Roll: Assists with directional control during rollout after landing.
Considerations
- Brake Wear: Overuse can lead to premature brake wear or overheating.
- Speed Sensitivity: Less effective at high speeds; aerodynamic controls dominate.
- Pilot Skill: Requires precise technique for safe and effective usage.
Yaw braking enhances control and maneuverability in critical ground phases and is an essential part of pilot training, especially in tailwheel and rudder-dependent aircraft.
