Engine spool up on approach - Airbus
Most airlines have engine spool up as a criteria for a stable approach, e.g. engine spool up at a certain altitude, for example 1000'
Normally this is considered as engine being above idle when passing the above altitude.
The Airbus has an Approach idle mode.
I have just heard that being at Approach idle is sufficient, you do not need to have engine spool up.
Is that correct ?
