How should you handle an engine anti-ice malfunction on takeoff?

• A. Abort takeoff immediately.
• B. Ignore and continue.
• C. Follow ECAM/QRH for anti-ice failure, ensure alternate procedures, and configure for safe climb with appropriate protections.
• D. Switch to manual thrust management.

Answer: (C)

When an engine anti-ice fault shows up on takeoff, the proper response is to follow the ECAM/QRH anti-ice failure procedures and apply the alternate procedures published there, then configure the airplane for a safe climb with the appropriate protections. This approach uses proven, aircraft-specific steps to verify the fault, switch to any available alternate anti-ice method, and set up thrust, speeds, and configurations to ensure you can climb safely within the airplane’s protection limits. It prevents ad hoc decisions that could compromise engine safety or performance during the critical takeoff phase.

In practice, this means you consult the QRH/ECAM for the exact actions to take with an anti-ice failure, complete the required checks, and adjust the airplane’s configuration for climb (thrust, airspeed, flap/landing gear as applicable) so engine and flight protections remain intact. Aborting immediately or continuing without guidance would not account for the faulted system and could compromise safety, while switching to manual thrust management is not the prescribed procedure for this fault.
