Description: The Bell 525 Relentless is a super-medium helicopter intended to serve customers in the oil�& gas, search�& rescue, helicopter emergency medical services and VIP/corporate transport sectors. The 525 features superior payload and range, cabin and cargo volumes and crew visibility. Bell Helicopter claims that listened relentlessly to their customers using their feedback to provide them with the right product that suits their needs. The new aircraft will be powered by the low fuel consumption General Electric CT7-2F1 engine which also features low cost of operation, FADEC and advanced materials, primarily in the turbine section. Bell Helicopter unveiled the new 525 Relentless aircraft in February 2012 at the Heli-Expo exhibition in Dallas, Texas. The first CT7-2F1 engine deliveries are planned for 2014 with the aircraft entering into service in 2015 or later.

The Bell 525 Relentless helicopter will be capable of carrying up to 16 passengers. The aircraft will be equipped with state-of-the-art ARC Horizon flight deck providing unparalleled crew situational awareness using a glass flight deck and advanced fly-by-wire flight controls from BAE Systems. The ARC Horizon will debut the Garmin G5000H integrated avionics suite with high resolution primary flight displays (PFD) and multi-function displays (MFD). The new flight deck will allow decreased pilot workload. The GE CT7-2F1 2,000-shp class engine will be the key to support long range, high payload missions.
