PH Test switch

[deephack]

Does anyone know what the PH Test switch does at the rear of the left console beside the emergency hydraulics and SHARS switches?

I think it's just a pitot heat test switch, but I don't think that it's functional in game. I don't have any evidence or source to prove this though.

That would make sense given that the default position is auto and the pitot heat is automatic in the Jeff.
