B737 NG Questions.
Just looking at the 737 CBT, it does not cover the questions below. Could somebody please assist.
1. If the APU is u/s on the NG. Do you need conditioned air, high pressure air and a GPU to get going or can a airstart machine provide the high pressure for the start and still be used to send air through the packs for air conditioning?
2. What sort of pressure would the source providing the conditioned air and the high pressure air for starting operate at?
3. What is the temperature range for the conditioned air?
4. If the APU was u/s which engine would you start first?
5. What is the minimum duct pressure required for starting?
Thanks in advance.
BE.
