Mmmm...
No Airconditioning .... Bloody stupid decision especially for Australian conditions.
Heat stress is an added complication just not needed on an EMS sortie.
Had the fantastic Garrett system in he BK117 used in Melbourne would produce ice out of the ducts during mid summer flights.
In winter or on really wet days when the crew gets into the machine and starts putting all that water vapour into the cabin the a/c would be able to dry the atmosphere and give you a chance to keep the wind screens /windows clear of mist.
A/C should be MANDATORY on EMS machines .... is it not with road ambulances?
