Disengage autothrottle
- Both power levers to TOGA - Gets you TOGA on the live engine
There is no need to open the live engine to go-around power. The combination of full power and bringing flap to 15 while descending on the glide slope will generally guarantee a rapid increase of airspeed well beyond the desired speed for a flap 15 landing. The technique is to use sufficient thrust to accelerate to and maintain the desired airspeed. The Boeing FCTM also states you can land with current landing flap if performance permits.
