LTR-97 Fiber Optic Gyro VG/DG Replacement System
The LTR-97 is a Vertical Gyro/Directional Gyro (VG/DG) replacement system that uses Fiber Optic Gyro (FOG) technology in a strapdown configuration to provide superior aircraft attitude and heading.
Ideal for retrofit, the LTR-97 offers users of aircraft such as the 727, 737, DC-8, DC-9, MD-8X, and C-130 a cost-effective, advanced technology replacement for their antiquated, failure-prone mechanical VG/DG systems.
With up to ten times the Mean Time Between Failure (MTBF) of mechanical VGs/DGs, the LTR-97 improves dispatch reliability, thus reducing maintenance costs. Not only is the LTR-97 the smallest, lightest, least expensive FOG-based unit on the market, it takes just minutes to install, uses existing aircraft power, and requires no changes to the aircraft wiring.
