Human Factors; Procedure
We were flying the RNAV 17 missed approach procedure to the hold. ATC advised us that we were supposed to be flying to GLARA intersection for the missed approach on LOC DME 17. The mis-communications between us and ATC put us south of UAO and TRACON told us were we supposed to be East of UAO. The confusion between the two missed approach procedures (LOC DME 17 and RNAV 17) for Aurora could possibly cause some disastrous situations. We continued to GLARA without further incident.
Reporter stated that they had requested the RNAV RWY 17 approach and were conducting that approach. Upon initiating the missed approach procedure; ATC queried the pilot asking where they were going. When the pilot replied that they were doing the RNAV 17 missed approach; ATC said they should be flying the LOC DME RWY 17 missed approach. Reporter said they were not aware that ATC had issued them the LOC DME RWY 17 approach until that point. Reporter noted that the final approach course numbers for the two approaches are identical; however the RNAV missed approach course continues south; while the LOC DME missed approach course turns eastbound.
Flight Instructor reported that while executing the RNAV 17 missed approach procedure to UAO; ATC informed them they had been cleared for a different approach to the same runway.
