The present invention provides a communication channel establishment method that establishes a communication channel used particularly when a cipher communication is carried out. The supply panel provides conditioned air to the cab. The fuse device may be configured to separate in response to a separating force such that the drogue may separate from the elongate hose prior to the exertion of a damaging force, a non-certified force, or an unknown aerodynamic force on the elongate hose, on a probe carried by a second receiver aircraft, or on the tanker aircraft. Further still, approaches provide for the ability to specify 3D attributes of the interface elements.
