FSXXI: Proven Rotary-Wing Training

Key Facts

#1 Provider of Simulators to the U.S. Army
230,000+ Hours of Training Since Program Inception
39% / 8% Providing 39% of Flight Training for 8% of the Flight Training Budget

The U.S. Army’s Flight School XXI (FSXXI) is recognized as the largest helicopter simulation training program in the world. Each year FSXXI trains 1,200 new student pilots with no previous flight experience to become combat mission aviators. In addition, FSXXI trains 1,600 rated Army aviators to operate new aircraft platforms annually. The U.S. Army spends only 8 percent of its annual training budget to train 39 percent of its annual training requirements via FSXXI.

L3 Link is a key training technology provider to the program. FSXXI utilizes a fleet of more than 30 L3 Link simulators, including Operational Flight Trainers (OFTs) and Reconfigurable Collective Training Devices (RCTDs). 

FSXXI—L3 Link Simulator Highlights:
  • Reliability—since the program’s inception, L3 Link-built training devices have provided more than 222,000 flying hours at 99.7 percent availability
  • Collective training capabilities—in collective aircrew training, crews can operate L3 Link-built RCTDs that simulate the AH-64A/D Longbow, CH-47D/F, UH-60A/L/M and OH-58D  
  • Platform breadth—L3 Link-built OFTs are currently being used by crews to train on the UH-60L/M and CH-47D/F
FSXXI—L3 Link Technology
  • Three-degree-of-freedom vibration platform and six-degree-of-freedom electric motion system 
  • 200° horizontal x 45° vertical visual display, supplemented with pilot and copilot chin windows
  • PC-based image generation system for high-resolution visual scenes; also supports night vision goggle training using tactical night vision devices
  • High-fidelity OFT software modeling for accurate simulation of onboard components
  • Physics-based blade element model and electrically driven servo flight control system 
  • OFT cyclic and collective controls to replicate actual aircraft hardware
  • Geo-specific databases use photo and satellite imagery to provide a realistic, high-fidelity virtual environment that immerses aircrews in dynamic training scenarios 
  • L3 Link-built RCTDs provide terrain- and threat environment-specific training for all aviation units as the last training and evaluation event prior to combat deployment
  • RCTDs integrated with projected instrument display and physical fidelity modeling of critical switches 
  • RCTDs include a helmet-mounted visual display for 360° field-of-regard
  • Each RCTD configuration simulates specific aircraft radio communications and digital messaging capabilities
  • RCTDs model aircraft survivability equipment and weapon systems for each platform and are fully interoperable with the U.S. Army’s OneSAF threat environment
