This is a work in progress
The rudder flight control surface is inoperative. The Remote Electronics Units (REUs) and/or control surface Hydraulic Actuators (HAs) or Electrical Back-Up Actuators (EBHAs) on rudder is inoperative resulting in the flight control surface being in a damped bypass (float) or jammed position.
The loss of rudder will result in reduced lateral-directional (roll-yaw) control effectiveness. The following additional flight control functions will be inoperative.
- FCS Yaw Damping: Inoperative.
- FCS Yaw Trim: Inoperative. The yaw trim indicator will move in response to Yaw Trim knob inputs but the aircraft will not respond as the rudder is failed.
- FCS Turn Coordination: Inoperative.
- Steep Approach: Unavailable.
To view the FCS Synoptic Legend, refer to 03-13-190, FCS Synoptic Legend.
- Autopilot . . . OFF
- Airspeed . . . 285 KCAS / 0.90M maximum
- Sidestick, Roll Inputs . . . Minimize
- Verify rudder operational status Apply small rudder inputs
- To minimize sideslip buildup (Dutch Roll):
- Select Airport for Landing
a. If the airplane yaws in response to rudder pedal inputs:
(1) YAW TRIM . . . As required
(2) Airplane . . . Land as soon as practicable
b. If the airplane does not respond to rudder pedal inputs:
(1) Airplane . . . Land as soon as practicable
(2) Altitude . . . 35,000 feet maximum
(3) Airspeed . . . 285 KCAS / 0.90M maximum (VREF +10 KCAS minimum)
(4) Yaw . . . Use differential thrust (as required)
The use of autopilot may reduce workload and reduce Dutch Roll oscillations.
(5) AP As required
a. Roll . . . Use smooth inputs
a. Select Airport Select one with minimal gusting wind conditions (if possible)
b. Landing . . . Controllability Check Perform
(1) Refer to 03-13-10, Landing Controllability Check.
c. Runway . . . Select longest / widest runway with most favorable crosswind (from opposite side of rudder trailing edge)
Landing distance should be based on VREF +10 KCAS to touchdown increased by a 1.25 factor for a shallow approach.
Wheel fuse plug release may occur due to added landing speed under combinations of high field elevation, landing weight and OAT.
d. Landing . . . Distance Recalculate with a 1.25 factor
a. Approach . . . Plan long / shallow final approach and wide pattern with shallow bank angles
b. Airspeed . . . VREF+10 KCAS minimum to touchdown
c. Autothrottle . . . Disconnect
d. Runway Alignment . . . Use Differential Thrust
a. Landing . . . Flare Minimize / Maintain throttle positions
b. Nosewheel . . . Lower to runway immediately
c. POWER LEVERS . . . IDLE (after nosewheel on ground)
d. Thrust Reversers (Left and Right) . . . Minimize use above idle position
e. For directional control on ground:
(1) Rudder Pedals / Differential Brakes . . . As required
