With all do respect
My dear feiend i found ipad realy useful and oprational in flight i have checked its accuracy with nav sys of aircraft ( fokker 100) several time and its realy reliable the only thing needs to mention is that avoid using it contineously since desply on cause ipad warm up and heat up which cause to battry loss ...
Using it in short intervall is a good remedy and avoid direct sun light but overally its a problem you have not to deal with in night flight .
Wish you all safe and sound flights .
