If wind is +30 degrees off the nose with windspeed between 5 and 30 knots, what procedure should be followed for rapid relight?

If wind is +30 degrees off the nose with windspeed between 5 and 30 knots, what procedure should be followed for rapid relight?

• A. Apply up to a maximum of 75% N1 before brakes released, then set TOGA thrust by 60 KIAS
• B. Set TOGA thrust immediately at 60 KIAS
• C. Idle thrust until brakes released
• D. Set TOGA thrust by 70 KIAS after brakes released

Answer: (A)

Rapid relight is about getting the inoperative engine spinning up to a safe level before committing to a full thrust takeoff, while keeping the airplane controllable in a crosswind. With wind 5–30 knots from about 30 degrees off the nose, you hold the brakes and bring the failed engine up to about 75% N1. This pre-spooling ensures the engine core and starter are ready for a quick relight and helps avoid a surge or stall if you light the engine with too little spool. Once you’re at that ready state, release the brakes and advance to TOGA thrust by 60 KIAS. This timing gives you a stable acceleration point and enough airspeed to maintain control as the engine relights and produces takeoff thrust. Choosing TOGA immediately at 60 KIAS without the pre-spool could lead to a sudden power change and directional control issues in the crosswind. Waiting until 70 KIAS after braking would delay the relight and risk loss of timing or control.
