 NOTE : Engine light-off will normally occur within 2 to 3 seconds after you
____ set the ENG MASTER control lever to the ON position. If light-off does not occur within 15 seconds, abort the start.
 NOTE : Immediately abort the start if a fast EGT increase, followed by slow
____ N2 acceleration occurs. These can be symptoms of incorrect fuel scheduling, faulty instrumentation, engine damage, low starter air pressure or too much engine deterioration. Monitor the upper ECAM display unit for possible messages. You can continue starts with slow N2 acceleration from light-off to idle, and followed by a low EGT indication (unsatisfactory fuel schedule). You must correct starts with temperatures of more than 725 deg.C (1337 deg.F). Normal start temperatures are less than 500 deg.C (932 deg.F).
 5. When the engine idle speed is
 stable, on the ENG panel 115VU:
