All Bell civil helicopters are now approved to use GE Aerospace’s Rotor Analysis Diagnostic System-Next Generation (RADS-NG) for rotor track and balance and diagnostics. RADS-NG, which replaces GE’s RADS-Advanced Technology and Aviation Vibration Analyzer systems, is the company’s latest portable rotor track and balance solution. More than 5,000 RADS-AT units have been delivered and it is standard equipment for the U.S. Army and Navy.

The first RADS-NG delivery was in 2024 to Germiston, South Africa-based Henley Air, and since then, GE has delivered these systems to Bell for flight test and pre-delivery checks. Bell and other customers helped refine the next-generation system, which also has a flexible configuration to be used for other rotorcraft types such as tiltrotors, coaxial rotor helicopters, and eVTOL aircraft.
