The Cabri G2 is fully certified to EASA CS-27 and FAR-27 regulations, which cover helicopter with a MTOW of less than 3175 kg. These rules have been refined for over 50 years, drawing on the experience of various experts, to produce some of the strictest safety regulations in general aviation today. Hot conditions. Cold conditions. High altitude. Under vibration. In lightning. In magnetic radio interference. For the life of the aircraft, under every conceivable condition an operator could subject the Cabri to, safety comes first.
The Cabri main rotor was designed with training in mind, to allow a safe and efficient autorotation practice.
Its composite blades have a very high inertia, latest generation evolutive airfoils. They give the helicopter an autorotation ability which exceeds by 50% the minimum US Army requirement, and is twice that of some popular training helicopters. This ability, together with a very large range of RPM, make the rotor speed control easy, safe and demonstrative in autorotation. In order to further help the pilot in these stressful flight phases, the rotor and engine tachometer ergonomics were designed with experienced instructors as advisers.
Statistics speak for themselves : the conventional tail rotor is a bad contributor to accident records, causing more than half of them for some helicopter families.
The Cabri’s Fenestron® is the result of 25 years of experience, and is covered by several patents.
Its tough shroud, and energy-absorbing skid, with a 1.2 meter ground clearance, provide an unmatchable safety for people standing around, during close-to-the-ground maneuvers, and during landing in cluttered area.
Flight-tested in precise maneuvers in crosswinds above 50 kt, the Cabri tail rotor is never a flight limitation.
The Cabri is the only piston helicopter designed from scratch with occupants protection in mind. It’s the only one to meet the recent EASA CS27-and FAR 27 regulation, that requires a high impact energy absorption.
For forward-velocity impacts :
- Energy absorbing structure,
- Four-point harnesses with reel,
- Occupants head trajectography.
This is 8 to 15 times more energy absorbed than competitors. High-absorption stroking-seats maximize your safety in the event of an accident, the Cabri’s fuel tank and circuit are made with technologies The whole helicopter’s architecture was designed to absorb high energy impacts. coming from combat helicopters and Formula 1 race cars : dual-structure with thick, indestructible fuel bladder, reinforced fittings, etc.
To validate it, the fully loaded circuit was submitted to a 15 m free-fall, and there was no leakage. 8 to 15 times higher energy absorption when compared to competitors. Thus the Cabri provides you with a level of safety that was previously only available to the military and expensive turbine helicopters. Because it was unfair that you were better protected in your car than in your helicopter!
The CABRI excelled in the certification tests of the cabin safety cell and the adjacent structure in accordance with EASACS-27 and FAR 27 standards. These tests include firing from a bench-catapult, designed and carried out by the Millbrook company in Luton, U.K., under the control of EASA. During testing the safety cell undergoes horizontal loads of up to 19G and vertical loads of up to 30G. These are measurements of the forces carried by the seats, giving a safety margin of 15-50% for the occupants. Success in theses tests was extremely important for certification, as it validated the design and manufacture of the airframe. The anti-crash structure was one of the principal technical challenges of the program. It was the main objective of the research programs into improving aircraft safety. Making survival possible with vertical speeds of 2′ 000 ft/min, which is well above the speed in autorotation. This technology, an important aspect of improvement of safety, has enabled the CABRI G2 to be the very first piston powered helicopter to pass the new EASA/FAR standards.
The puncture proof fuel tank is capable of withstanding an extreme impact. During testing, the fuel tank was filled up to 80% capacity and dropped from a height of 15 metres. The tank passed the test by surviving this impact without spilling any of the contents.
