I am considering purchase of PMDG 737. Does it have an auto start feature so one does not have to go through a detailed start-up each time? I usually like the realism of going through check lists but sometimes just want to get in the air to practice approaches, failures, etc. Time for check list may not give me time for the other in a busy schedule. Thanks Gary

You can save the panel state I think, saves you time! :) Or you wait for the NGX ofcourse :)

Not sure about the NGX itself but previous PMDG aircraft already have the engines running once you load the aircraft. All you'd have to do is load the FMC and you're ready to go. As suggested above, if you constantly practice at the same airport, you could save a panel state with the FMC already loaded.
