Narrative:

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 pre departure clearance. After reviewing the pre departure clearance; 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 pre departure clearance. Non-standard format for dp change instructions. ATC should use standard route change format or not send pre departure clearance to issue alternate clearance instructions. As a crew; we should have queried the irregular format.

Title: 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.

Narrative: 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.
