Yes, same here, A380, 747, A330 and instructor pilot take offs all swerve hectically near about half way done the run way. I also have the 'stall warning' come on when I'm not in a stall or the alarm will sound and the high pitched sound will ring continuously in the background, even after the aircraft recovers. I'm using it on an iPod touch 5th generation with iOS 6. Never had problems until this last update. However I have to say that I just love this app, it's amazing. Once those glitches are fixed it will be perfect. I'm looking forward to seeing how this develops over the years. Great app, thank you!
