Cooling Method - Commercial Aviation electronics?

    I'm trying to run down some comparisons on cooling methods for electronics in various outdoor environments; large scale aviation with its temperature extremes and moderate vibration levels would make a good data point, for things boiler plate avionics and passenger video services. A Boeing engineer told me in passing that he believed most of it was conduction cooled, versus forced air cooled, at the circuit card level, I'm guessing something like http://standards.ieee.org/reading/ieee/std_public/new_desc/busarch/1101.2-1992.html" [Broken]. If true, that would necessarily limit the choice of vendors and probably means a lot of in house design, driving up the costs. Can anyone comment?
