Sidestick Active / Passive Unlinked

G500 Abnormal Procedures

This is a work in progress


AFM Procedure

[AFM, §03-13-180]

Possible Cause

The affected sidestick is operating in passive mode due to an internal failure while the opposite sidestick remains in active mode.

System Impacts

  • Autopilot Backdrive: Not available (Autopilot remains available).
  • Roll Trim Backdrive: Not available (Roll Trim remains available).
  • Sidesticks: Unlinked. The passive stick will not be capable of active “feel” gradients.
  • Stick Shaker: Not available on passive stick.

Corrective Action

    NOTE

    Each flight crew will not “feel” the sidestick inputs being made by the other the flight crew member. Pilot recognition will rely on an unexpected airplane response and / or alerting by the Dual Stick Input (caution) CAS message.

  1. In Flight

  2. a. Pilot Flying . . . Positively identify pilot flying, and subsequent control transfers

    b. PITCH TRIM . . . Maintain trimmed flight condition

    c. Autopilot . . . OFF

    d. FLT CTRL RESET . . . PRESS and RELEASE

    e. Autopilot . . . As required

    f. If the CAS message remains displayed:

    (1) Flight . . . Continue

    NOTE

    The passive stick may display less than optimal handling qualities, particularly during high speed cruise flight and low speed approach and landing. Recommend pilot flying use the active stick.

    (2) Normal Approach and Landing . . . Perform

  3. On Ground

  4. a. FLT CTRL RESET . . . PRESS and RELEASE

    b. If the CAS message is displayed:

    1) Airplane . . . Do not dispatch

    c. If the CAS message is no longer displayed, and both sidesticks are operational:

    (1) FCS Test . . . Perform

    d. If the FCS and Sidestick related CAS messages are no longer displayed following FCS Test:

    (1) Flight . . . Continue
