Ive installed an automatic alternate air gate from R22 helicopters to my FAB. One less lever to pull if the engine 'goes off' if the filter gets blocked... it just opens automatically. I decided it would be useful to know that the alternate air gate was open, so added a sensor that will lluminate a light in the cockpit when the gate opens. Need to fill out a Mos 3 form for the installation. Pleased with the result.
