Engine failure during take-off at CPH.

[Walder]

On the 737 more than 40% N1 is not recommended with taxi speeds below 10 knots, due to risk of FOD.
On taxi out up to 40% N1 on both engines might be required as “brake away thrust” on a fully loaded 737.
If only one engine is operating, much more than 40% N1 is required and risk for FOD is severely increased.
In case of a severe CTOT, we might taxi out on both engines, then shut them down and do a restart when it is time to take off. Normally the delay should be more than 15 minutes if a shut down is done. Remember not to shut down the APU. Saving is lost, if the APU has to be restarted!

On taxi in single engine is only recommended if taxi time is more than 3 minutes, and no full stops are expected.
