ATC Issue All Types; Deviation - Track / Heading All Types; Deviation / Discrepancy - Procedural Published Material / Policy; Deviation / Discrepancy - Procedural Clearance
Air Traffic Control Issued New Clearance; Flight Crew Became Reoriented
Environment - Non Weather Related; Procedure
When we received clearance; we were given NAMUB 2S departure flight plan route. NIMBY was on our flight plan to turn left at 9 DME to NAMUD and intercept a T airway southbound. When we were handed off to Munich they queried us on our departure and said we were filed on the ODLUN2s with a right turn north to ODLUN intersection. They flew us north for about 25 NM the westbound for approximately 50 NM then south toward GTQ VOR . None of which was on our filed routing. No explanation; no traffic conflict; no clue!
Captain called for and received clearance. Both pilots listened on headsets. We heard and read back the NAMUB 2S departure. This made sense for our direction of flight and our flight plan fixes. The person handling Clearance was also handling the push and ground control; duties. The push back; start and taxi were all normal. The noise abatement procedure and initial route of flight were thoroughly briefed. We were switched to tower and departed shortly thereafter. After takeoff tower switched us to departure. He seemed surprised at our route of flight and gave us a heading of 350. This was a large turn in the opposite direction of what we expected. Radio congestion was a factor; but eventually the controller stated that we were supposed to have flown the ODLUN 2S departure. Needless to say this was a surprise to us. This was my first departure out of EDDP. I had no reason question our departure; as I was convinced that were heard and read back the correct clearance. From now on I will have to insist that we read back phonetically the departure clearance. The language barrier is significant. I wonder if it is possible for the company Field Officer/Agent to coordinate with the local controllers and find out what the usual SID/STAR would be in use; and file that accordingly.
An aircraft departed EDDP filed on the NAMUB 2S but ATC stated they should have been flying the ODLUN 2S and so issue that change to them.
