Overview
‘Designed with customers, for customers’
The new-generation 16-18-seat H175 raises the bar for medium helicopters, combining a best-in-class 434 cu. ft. cabin with a large 685 gal. standard fuel capacity for extended range.
Designed from the outset with the close involvement of operators, the H175 is suited for a wide range of missions, including offshore, search and rescue, VIP, utility and MEDEVAC operations. It features an advanced avionics suite, including a digital 4-axis autopilot, and provides occupants with the highest standards of safety – incorporating energy attenuating seats and oversized Type IV emergency exits. Utilizing a rugged aluminum alloy airframe, the H175 integrates an MSG-3 maintenance philosophy for ease of support.
‘No detail escapes Airbus Helicopters’
A variety of training devices can be made available at initial delivery that include:
- Totally portable, computer- and Web-based training
- Avionic and part task trainers
- Light training devices (in effect, small control-panel simulators)
- Full flight simulators
- Actual training aircraft
Not only is the new H175 a superb technical success, but also offers excellent service support and training. Airbus Helicopters does everything possible to make sure that the H175 is a user-friendly helicopter at its customer’s service.
The H175 exceeds EASA CS29 crashworthiness requirements. In addition to general fail-safe design and fully redundant systems, emergency egress capacity exceeds EASA Type IV
With oil platforms farther and farther out to sea, two hour helicopter rides are now common. Therefore cabin comfort is becoming as important as cost per seat.
The H175’s spacious cockpit was designed by pilots for pilots. Wide, hinged, hydraulically assisted doors provide effortless access and egress. Immense windows offer an exceptionally large field of vision. The Airbus Helicopters- exclusive, advanced human-machine interface is designed upon helicopter specifics, not just adapted from general aviation. The all-glass, 6X8 inch multi-function LCD displays, plus optional central mission display, offer ideal ergonomics and symbolizations that are truly pilot friendly. The common cockpit concept throughout the Airbus Helicopters range greatly simplifies the addition of the H175 to existing fleets. Advanced caution and warning systems have built-in test functions for fault indication and maintenance of all critical systems cautions and warnings, also associated with audio tones. The H175’s state-of-the-art avionics are derived from the acknowledged H225. The 4-axis dual duplex autopilot provides unrivalled precision and stability for automatic transitions to hover on ships or on shore. It is linked to the Flight Management System for area navigation and all other upper modes: trans up, trans down, hover, etc. All of these pilot-friendly systems, added to the Full Authority Digital Engine Control, substantially reduce pilot workload and enhance pilot precision, even in roughest weather conditions. Open architecture permits easy connection of navigation sensors. In addition, the vast central console comes completely configured, but still has room for many customizations.
Customer advice and a logistic support analysis based on most advanced standards showed that a new maintenance approach for the H175 would provide significant economic savings. The benefits were achieved, first through a reduction of maintenance workload and costs, by reducing the number of maintenance tasks and their frequency. Secondly, by improving reliability of the different systems. The H175 is a major step in terms of development process and technical integration, with the use of a DMU (Digital Mock Up). This DMU is a virtual helicopter, fully represented in 3D, used as a common basis for all the designers. In addition, this DMU provides outstanding information to generate the documentation and prepare the maintenance operations. The result is Increased availability, reliability and safety, with an inevitable decrease in maintenance costs. Application of ‘’MSG-3’’ methodology to the elaboration of the Master Servicing Manual led to suppression of the usual “after-last-flight” visit, reduced frequency of the Technical Inspection, and complete suppression of the Major Inspection. The Pratt & Whitney PT6C engines are renowned for excellent Time Between Overhaul (5,000 hours). The Spheriflex® design rotor head requires only “On-Condition” maintenance. The rugged but simple airframe has a metallic structure made essentially of extremely light but rigid aluminum alloy. Maritime corrosion treated, it is easy to maintain and easy to repair. Airbus Helicopters offers a comprehensive array of repair and overhaul services to ensure maximum availability with fully controlled costs. Services range from basic OEM repair to comprehensive Parts-By-the-Hour and Oil & Gas Availability Program (OGAP).
The H175 is powered two proven and reliable Pratt & Whitney PT6C engines. The five-bladed main rotor and three-bladed tail rotor are equipped with blades of a new-generation, profiles and tips. These blades, not only offer a reduction in vibration and noise, but also provide increased lift power and speed. The Spheriflex® design minimized bearing rotor head is damage tolerant. The H175’s brand-new main gearbox has two accessory gearboxes for double redundancy and is capable of a 30 min flight after total loss of oil. De-clutch capability gives Auxiliary Power Unit benefits without the cost and weight of additional equipment. The fuel system, under floor, is a four-tank standard configuration carrying more than 600 US gals (2,300 liters).
The H175 has been designed to make it operational friendly. Therefore it will offer extreme cabin versatility.
The H175 is powered by proven and reliable Pratt & Whitney PT6C engines.
The H175’s wide cabin carries up to 16 passengers. In fact, it is the only 16 pax craft in its class. It provides unrivaled comfort and the highest levels of accessibility and visibility. The H175 has the highest useful volume and payload, as well as, the highest performance and range in its class. This means it can carry more passengers on more round trips per day, at a lower cost per seat, than any other
