The Bell CH-146 Griffon is the Canadian military variant of the Bell 412EP, a multi-use utility helicopter. The CH-146 is used in a wide variety of roles, including aerial firepower, reconnaissance and aero-mobility tasks.[1]

In 2007, the CH-146 is also one of the four aircraft taught to medical personnel in the Canadian Aeromedical Evacuation school.[citation needed]

[edit] Design and development

The Griffon was built at Mirabel, Quebec, at the Bell Canadian plant. They were delivered between 1995 and 1997 in one of two configurations, the Combat Support Squadron (CSS) version for search and rescue missions, and the Utility Tactical Transport Helicopter (UTTH), which carries a crew of three and an eight-man section.[1]

The Griffon can be equipped with various specialized bolt-on mission kits, which can enhance the performance of the Griffon, from increasing range, improving protection against enemy fire, etc.[1]

The Canadian Forces purchased 100 aircraft. 85 are serving in the tactical-helicopter role at CFB Edmonton, CFB Petawawa, CFB Valcartier, and CFB Gagetown. The remainder of the aircraft are being used in search-and-rescue roles in Combat Support Squadrons at 4 Wing Cold Lake, 3 Wing Bagotville, and 5 Wing Goose Bay as well as reserve air force units including 400 Squadron at CFB Borden and 438 Squadron in St-Hubert, Quebec.[2]

One interesting feature of the Griffon is a small camera mounted in the nose of the aircraft pointed up at the rotor. By observing a small yellow paint stripe on the rotor, the autopilot can detect the classic "hoola-hoop" motion and correct it, smoothing the ride.[citation needed]

Minor disassembly permits transport of the Griffon by CC130 Hercules cargo aircraft for long-distance deployment.[1]
