Certified Flight Instructor Instrument – Aircraft Horizon Review

This is a great application for classroom demonstrations. If you are thinking of purchasing it as an emergency backup Attitude Indicator in the airplane it will not work for that. I have flown with this in the aircraft and the only indications that are accurate are pitch information as long as the airspeed remains constant. No bank information is presented in coordinated flight as the accelerometer in the Ipodtouch is incapable of detecting that the bank is occurring due to the centripetal force created during the turn. Yawing the aircraft with the ruder produces a bank indication opposite to the direction of yaw. Relying on this application in the aircraft during flight in instrument meteorological conditions could lead to total loss of aircraft control and possible structural failure due to excessive G loading of the aircraft.
