I’ve used iPhone for air navigation for several years now. (Skydemon, Air Nav pro, easyvfr basic). No problem on any iOS device. Until now. Bought an iPhone X. Problem, it shows the lat-long position, but NO altitude. Tried it on three iPhone X’s (also Dennis’s iPhone) All the same problem, with all kinds of altitude apps.
Contacted Apple. Senior engineers now say that the gps is not for active tracking. I was really angry and confused. Could not believe their answer. Have now done additional diagnostics. Contact appointment for tomorrow to read out my iPhone X and 5s.
Have also contacted PocketFMS to ask if they have experienced problems. They will now contact Apple trough their developers to find out more.
As it seems at the moment all air navigation apps are then obsolete for iPhone X users.
Can Skydemon maybe also contact Apple development for enquiries?
Does anyone use Foreflight to test and maybe get them to contact Apple?
Hope to hear from you soon.
