Operation to transmit the intention of releasing the flight according to the agreed transfer conditions.
Depending on the LoAs: e.g. expecting a further AssumeFlight operation or just waiting for a radio contact to release the flight.
This is an OLDI COF (Change Of Frequency) message equivalent.
This operation also offers the possibility to hand over the flight to another crossed responsibility than the expected one (eq. shortcut forceHandOver input). In that case, it is expected to provide explicitly the new responsibility traversal to which the transfer is performed, as well as the identifier of this responsibility (available in the SFPL ControlSector list).
This operation also offers the possibility to hand over the flight to a responsibility not in the list of crossed (eq. delegate input)..
