A320: Questions for the Pros
As I am digging deeper and deeper into the workings of A320, I have two questions that I would like to have answered:
1) Why are the PACKs turned off just prior to take-off? Is it a thrust issue? That would seem unlikely as the engines should produce more than enough thrust -- or in other words, the PACKs should not take such a toll on thrust that it would become an issue
2) When setting up the FMGC for both departures and approaches, how do you determine what NAVAIDs to specify in the FMGC? From what I can gather, sometimes you will put the ILS in both channels, sometimes not. Any clarifiaction on that would be greatly appreciated.
