When a plane is at a gate, I assume those yellow/orange flexible pipes are the ones used to supply air to the plane. But I would also assume that electrical power is also supplied from the ground so that the aircraft need not rely on its APU. Is this a correct assumption ? So, if the airport does not supply forced air, wouldn't the aircraft at least use ground electrical power to run its fans and airconditioners ? Furthermore, I am somewhat puzzled at the though that the air conditioners under the fuel tanks would have caused the tanks to heat up so much. Where/how do air conditioning units on an aircraft dump their excess heat ? (at ground and during flight). Do they just dump in in the cargo hold ?
