Device: iPad 10th Generation
Operating system:17.5.1
I was attempting to land the 772, and passing through about 11,000 feet at 270 knots. I went to reduce the speed, and realized that the controls were completely frozen, and I couldn’t even get the control tab to open. I was unable to disable autopilot, control the throttle, or deploy the landing gear, flaps, or spoilers. Despite my best attempts, I received multiple Level 1 violations before realizing my only option was to abort the flight by forcing the shutdown of my iPad. What caused this? Would this be grounds for Appeals to remove my violation?
