The LTN-101 FLAGSHIP™ is an integrated global navigation, air data, inertial reference unit (GNADIRU).
Introduced in 1992, FLAGSHIP™ has established an exceptional reliability record of over 16,000 operating hours MTBF on such leading commercial aircraft as the Airbus wide and narrow body families, Canadair Regional Jet and CL604, and the Saab 2000. Now, with the incorporation of Autonomous Integrity Monitored Extrapolation (AIME®) technology, FLAGSHIP™ offers 0.3 navigation accuracy worldwide, 24 hours a day.
FLAGSHIP™ lowers ownership costs through:
- Increased functionality and flexibility
- Integrated GPS and air data
- ARINC 704/738-compatible without modification
- Interchangeable with 10-MCU ARINC 704 and 738 by use of adapter tray only
- Offers AIME® technology
- Provides LNAV advisory, VNAV, and growth to precision approaches
- New generation reliability
- MTBF of over 16,000 operating hours
- Minimal false removals
- Enhanced maintainability
- Advanced built-in test to Level II
- In-flight fault diagnostics
- System and module BIT history storage
LTN-101 FLAGSHIP™ Technology
FLAGSHIP's™ performance and reliability are based on a series of design innovations:
Four Mode Laser Gyro (FLAG)
The patented FLAG combines two 18 cm Zero-lock™ Laser Gyroscopes in a single cavity. Undithered and 40 percent smaller than conventional ring laser gyros, FLAG means long gyro life, high accuracy and reliability, and reduced costs.
Software/Hardware Implemented Partitioning (SHIP)
SHIP organizes major system functions such as GPS, inertial reference, and air data in modules, ranks them by criticality, and isolates them from all other modules in both execution and memory access. This approach eliminates corruption of one function by another and contains functional loss due to a fault.
Fault containment ensures minimal functional loss in the event of a fault by prohibiting its propagation throughout the system.
A major step in helping the air transport industry realize the promise of GPS, AIME® technology allows commercial aircraft to achieve sole means of navigation with GPS accuracy. AIME® is a patented software algorithm that integrates GPS and IRS to compensate for the inherent integrity problems of GPS. With AIME®, FLAGSHIP can provide commercial aircraft with 0.3 nmi navigation accuracy worldwide, 24 hours a day. Learn more about AIME®.
