Amphitech International has announced an initial sale of the first commercially available obstacle avoidance radar system for helicopters to Canadian Helicopters Ltd. (CHL) of Les Cedres, Quebec. The obstacle avoidance system, called “Oasys,” is designed to detect small obstacles, such as power transmission lines, at ranges of up to one nautical mile. The system will be installed aboard a CHL Bell 212 in service with a customer in Labrador.
Laval, Ontario-based Amphitech International received a limited STC for its Oasys helicopter obstacle avoidance radar as installed aboard the Bell 212. Oasys can penetrate fog, rain, smoke and haze to alert helo crews of potential dangers such as power lines, towers, buildings, terrain, trees and air traffic. Work on an STC authorizing Oasys installation aboard Eurocopter AS 350s is under way.
A laser obstacle-avoidance system now entering service on military helicopters might prove useful for civil applications. Selex Communications’ laser obstacle avoidance and monitoring system (LOAM), installed on six AgustaWestland search-and-rescue EH-101s for the Danish Air Force, is said to be suitable for light singles as well.
