“Honeywell’s Mark XXI and Mark XX II systems – our helicopter Enhanced Ground Proximity Warning Systems – are specifically tailored for the dynamics of rotary-wing performance and the flight characteristics of helicopters and help prevent collisions with ground, water and obstacles,” said TK Kallenbach, Honeywell Vice President, Marketing and Product Management. “The systems provide superior and potentially life-saving information for flight crews, even when flying in changing weather with poor visibility, in rough terrain, or at low altitudes.”

Honeywell plans to obtain formal HTAWS TSO approval for its helicopter EGPWS systems this year.

“The Mark XXI and XXII EGPWS ensure that all helicopter operators, including Helicopter Emergency Medical Services (HEMS) operators, have the right equipment on board to help avoid terrain and obstacles, such as towers,” Kallenbach said. “Ensuring the safety of flight crews, medical personnel, patients, and passengers is a number one concern.”

Honeywell’s safety systems for helicopters address the challenges of traffic, terrain and weather, helping to ensure safe flight and guard against Controlled Flight Into Terrain (CFIT), weather related hazards, and collisions with obstacles and other aircraft. The systems are designed specifically for unique requirements of helicopter operations.

Honeywell, which produced the first terrain avoidance system for commercial aircraft, produces a full range of aircraft equipment, from engines, auxiliary power units and other mechanical systems to Health Usage Monitoring Systems (HUMS) and avionics. Additionally, Honeywell produces the Integrated Primary Flight Display synthetic vision system.

“The Honeywell HTS900 engine is a new type design engine to provide superior performance at high, hot conditions, fuel efficiency, and operating costs” said Mike Cuff, Honeywell Vice President, Helicopters and Surface Systems. “This certification demonstrates Honeywell’s continued success in developing the world’s highest performance turboshaft engines for both the commercial and military segments.

“The Honeywell HTS900 engine produces more than 1,000 Shaft Horsepower (SHP) uninstalled at sea level on a standard day – and has accumulated more than 1,000 flight hours,” Cuff said. “Primary benefits of the HTS900 over previous generation engines are 5-10% lower fuel burn, on condition maintenance with no hard time scheduled overhaul limits, and a Dual Channel Full Authority Digital Engine Control (FADEC) to ease pilot workload and maintenance planning. Combined, the HTS900 offers operating costs that are 10 percent lower than previous engines.” Some of the new technologies in the HTS900 include superior high pressure ratio Dual Centrifugal Compressor, cooled single-crystal turbine blades, cooled turbine nozzles, effusion cooled combustor liner.

The Dual Centrifugal Compressor configuration increases engine power output and reduces engine fuel consumption while providing for future engine power growth.

The on condition maintenance of the HTS900 engine is enabled by scheduled bore scope inspections which can be performed by the operator or Honeywell.
