Cooling Requirements (All Models)
A.
General
(1)
The KGX and KGX control panel meet all TSO requirements without forced air cooling.
While each individual unit does not require forced air cooling, the combined heat load of
several units operating in a typical avionics location can significantly degrade the reliability
of avionics if provisions for cooling are not incorporated in the initial installation. Failure to
supply adequate cooling can lead to increased avionics maintenance costs and will void
the BendixKing Warranty.
