Footnotes
[fn:3] This includes high humidity, a warm atmosphere, and the presence of inorganic salts.
[fn:2] Full flight mission must be considered, from prior to the engine start, to after landing---including emergencies.
[fn:1] Moisture sensitive devices may experience issues with this test and require conformal coat or other types of protection.
