System Approved For 9 Degree LPV Approaches At 45 knots

The FAA has certified Bell Helicopter's precision Wide Area Augmentation System (WAAS) enabled glide path capability on the Bell 429. The aircraft is the only helicopter available with technology certified for 9 degree localizer precision with vertical guidance (LPV) approaches at a minimum velocity for instrument procedures (Vmini) of 45 knots.  Such a low minimum velocity allows for the Bell 429 to fly LPV procedures in steep approach conditions.

Using a modernized cockpit layout and navigation solutions the Bell WAAS capability, as demonstrated on the Bell 429, increases helicopter safety, mission efficiency and environmental sensitivity, while reducing precision approach limitations and associated operational costs. Many flights are grounded annually due to poor weather conditions, the WAAS capability allows for point-in-space approaches as low as 250 foot visibility.
 
Bell's 429 WAAS implementation changes the helicopter operating environment, allowing for the creation of a safer rotorcraft IFR system, providing a platform to put those capabilities to use and allowing for precision approaches in low altitude, urban areas. Designed, developed, implemented and tested by a government industry partnership, the continuing airspace infrastructure project will facilitate the creation of public use rotorcraft solutions and provide a solid framework for additional next generation national airspace developments. Along with Bell, the team includes the Federal Aviation FAA's Global Navigation Satellite System (GNSS) Program Office, the FAA Flight Standards Organization, Hickok and Associates, Air Methods Corporation, and the Mercy Medical Team.

"It is because of this collaboration we are able to provide the helicopter industry and our customers with innovative solutions that exceed their mission requirements," said Nick Lappos, Bell Helicopter chief technology officer. "It is only fitting that this capability be available exclusively on the world's most advanced light twin helicopter, the 429."

This technology is available immediately on all new Bell 429s delivered out of the Bell Helicopter Mirabel, Canada facility. Bell Helicopter is exploring the use of this technology on additional Bell aircraft. "WAAS technologies, when combined with the 429, provide all operators engaged in IFR operations a vehicle to complete missions that were unthinkable in the past. This total aircraft solution will increase the number of missions that are flown and ultimately save more lives," said Roberts.
