Belite’s RADIANT instrument line combines many functions into simple, small, lightweight units. The instruments utilize sunlight readable full color high contrast LCD screens which are also friendly with sunglasses.
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
Display is “sunglass friendly” - bright; readable with polarized glasses.
Also provides continuous system voltage display
Works between -20C and +60C
Weighs 1.6 ounces (50 grams)
