Does anyone know the whereabouts of any reports or discussions on the use of AirCon in helicopters. I'm wondering if there are additional benefits to providing the crew with a comfortable environment such as extending or contributing to the extension of the life of avionics instruments etc by providing them with a much less severe environment to operate in. Have tried Googling but get everything but (can't be @rsed to go beyond page 6). Any help gladly received.
