Aircraft G-Meter accurately models a traditional mechanical accelerometer (or "G-Meter") found in aerobatic aircraft.
This instrument registers "G" forces acting on the airframe during turbulence or aerobatic maneuvers. One pointer gives a continuous reading, the other two indicate maximum positive and negative loads. A reset knob is provided. In smooth, level flight the instrument indicates +1 "G".
For best results, ensure the iPhone/iPod is vertical relative to the direction of flight.
