I have the latest logbook pc pro for windows 7. I just got the ipad3 iOS 5.1. When I select model aircraft on the pc, igot list of associated "N numbers" that I have flown with that particular model, for example over the years I have flown several 172s, and after you enter the n number one it saves to list for selection later. However, on the iPad I don't have that "many to one" relationship. Is it because the way aircraft is static at initalization of the iPad sync the first time. It's a GREAT tool but, gets old entering n numbers...Thanks in advance!
