This instrument allows pilot to track G rate trend while doing a turn or aerobatic maneuver. Shows G trend history.
All instruments are designed for a standard 2.25” cutout, and use approximately 100milliamps of power from a supply of 8 to 14 volts. All instruments are dimmable.
Brilliant daylight readable LCD display
Provides current Gee’s in bar height form and percentage form
Shows 7.5 seconds of history, so the pilot can see the trend instantly
