Is there a general patent cross-licencing agreement between Airbus and Boeing?
As an example, US Patent N° 7,564,374 was granted 4 days ago to a Mr Winkler and covers a "method and device" for representing to the pilots an aircraft's progress in the vertical plane along its flightpath in a dedicated display window within a screen. This patent is assigned to Airbus; details can be accessed by typing the patent N° in the USPTO's search page here:
IIRC, this display technology will also feature on the 787 so that B will have to pay royalties to A to use it.
There must be a multitude of other such patents held by A and licenced to B and vice versa. Would they be governed by some sort of master cross-licencing agreement?
