How long must the ebgine remain idle during engine warm up?
Until oil pressure reaches normal opwrating range
What percentage of N1 must not be exceeded during warm up, and for how long?
During all starts, do not exceed 75% N1 for two minutes after start, or until all operating indications are in the normal range, whichever is longer.
