[AFM, §03-]

Possible Cause

The indicated aileron flight control surface is inoperative. The REUs and/or hydraulic actuators or EBHAs on the indicated ailerons are inoperative resulting in a damped bypass (float) or jammed position.

System Impacts

A loss of one or both ailerons will result in reduced lateral (roll) control effectiveness and reduced ground roll braking effectiveness.

  • Fuel Burn: Increased.
  • Steep Approach: Unavailable.

Corrective Action

NOTE

To view the FCS Synoptic Legend, refer to 03-13-190, FCS Synoptic Legend.

  1. Autopilot . . . OFF

  2. Airspeed . . . 285 KCAS / 0.90M maximum

  3. ROLLTRIM . . . Neutralize roll control forces

  4. Airplane . . . Land as soon as practicable

  5. If additional roll trim is required:
    a. Landing Controllability Check . . . Perform
  6. Refer to 03-13-10, Landing Controllability Check

  7. Approach and Landing
    a. Runway . . . Select runway based on minimum crosswind (less than 10 knots)
    b. Airspeed . . . Maintain VREF minimum until touchdown
    c. Landing . . . Lower nose wheels to runway without delay
