Known for its rugged, fuel-efficient and exceptional performance, the CT7-2F1 provides reliable power and performance for all missions.
The Bell 525 Relentless is the first commercial helicopter to incorporate the intuitive Garmin G5000H, a touchscreen avionics suite for enhanced situational awareness and improved pilot integration due to fewer hand/eye movements in the flight deck. Helicopter Synthetic Vision Technology™ (HSVT) gives pilots a 3D depiction of terrain, obstacles, traffic and more in any condition. With its proactive hazard interventions through high-bandwidth capabilities, the Bell 525 avionic system sets the new standard for vehicle control in austere environments – precisely, safely, consistently, taking operational safety to the next level.
The Bell 525's fully digital fly-by-wire flight controls allows operators to fly demanding missions in almost any environment safely and reliably.
