Looking at 1.24.10 P9 the table for NBPT there should be no NBPT using external power during the start with the APU INOP as the original poster is saying. This is not a fault but causes the IFE to reset if it is in use. Were you work everyone briefs the ISM not to start till after 2nd engine start and it is never written up when NBPT does not occur, should we be writing this up?
