Flight Crew Air Transport Pilot (ATP)
Confusion; Communication Breakdown
Deviation / Discrepancy - Procedural Published Material / Policy
Air Traffic Control Issued Advisory / Alert; Air Traffic Control Issued New Clearance; Flight Crew Requested ATC Assistance / Clarification
Procedure; Chart Or Publication; Company Policy
When cleared for takeoff; we were assigned the HITAG1 departure. We queried the Tower Controller and said we had the WINCO1 RNAV loaded causing him to cancel takeoff clearance. We asked if we should load HITAG1 and he instead issued runway heading to 5;000 FT. For vectors. He said he would contact our company as this change is being missed on PDC. After reviewing the PDC; we confirmed no change bars or route change advisory as listed in FOM guidance; however; in the text at bottom; the HITAG1 was referenced. Communication discrepancy between ATC and crew via PDC. Non-standard format for DP change instructions. ATC should use standard route change format or not send PDC to issue alternate clearance instructions. As a crew; we should have queried the irregular format.
After we had been cleared 'line up and wait' on Runway 8R; we were then 'Cleared for takeoff; RNAV HITAG.' I inquired that we were assigned the WINCO1. We were told that our takeoff clearance was cancelled. We immediately looked at our PDC and there were actually no change bars from our filed routing; but we both missed that HITAG1; WINCO transition was also listed on the PDC. We said we could load the HITAG if needed; and the Tower Controller said not to worry about it; 'cleared for takeoff; runway heading 090' and he would take it up with the company. Non-standard PDC route change; and for some reason both the Captain and myself missed the HITAG1 even being referenced in the notes. Had we noticed; we would have had to inquire with Clearance Delivery as there were two different SIDs referenced.
A crew preparing to depart MIA had its takeoff clearance canceled after ATC asked them to confirm they were assigned the HITAG1 SID but the WINCO1 RNAV was loaded in the FMS.
