ABSTRACT:
An extensible loading bridge for aircraft having an inboard end connected to a terminal and an outboard end adapted for connection to a parked aircraft. A heat exchanger on the outboard end supplies warm or cold air to the aircraft. Hot or cold liquid is supplied to the outboard heat exchanger from a source at the terminal end of the bridge and extensible flexible supply and return lines convey the hot or cold glycol to or from the outboard heat exchanger. A means is provided for maintaining the supply and return lines under tension and to take up and give slack to the lines when the bridge is retracted or extended.
