E&B Helicopters Gets STC for Audible Check Instrument System on Bell 407
E&B Helicopters Ltd. Avionics Division received an STC (supplemental type
certificate) for an audible warning system, designed for the Bell 407, to check
engine instruments.
The back-up audile system addresses the problem of a pilot pulling too much torque
while "long-lining," which can result in major component overhaul costs and down
time. It does this by automatically monitoring engine indicators, and alerting
the pilot aurally when limits are approached.
(Long-lining refers to lifting and carrying objects attached beneath the
rotorcraft by a long line.)
E&B says the system is cost effective,
easy to install, and is easily interfaced with other warning systems. 10-22-2007. |
