E&B Helicopters Ltd. Avionics Division is proud to announce that we have received an STC from EASA to add to our STC’s from the FAA and TC for an Audible Check Instrument warning system designed for the Bell 407. This brings another level of safety to pilots, is cost effective and easy to install. It is easily integrated with other warning systems on the market and monitors the TRQ, MGT and NG indicators.

The audible alert is activated when either the TRQ, MGT or NG indicators hit the red line. The beneficial part is that if an over torque or over temp situation arises while long lining it is usually too late once the pilot notices. This will give an audible warning so that the pilot can react to get out of that condition and save overhaul costs and downtime

As a backup audible system this will reduce the workload for the pilot and add another level of safety.
