Synopsis
Flight crew reported that when they entered the published holding pattern at OQUDI; which is the IAF for RNAV(GPS)13 Approach to SKX; the FMS turned the aircraft right instead of left as published. The IAF holding pattern is left turns and the missed approach holding pattern at OQUDI is right turns.
Narrative
Procedure turn on RNAV GPS 13 approach at Taos. Cleared direct OQUDI; cross OQUDI at 14000 ft; cleared RNAV 13 approach at Taos. Crossing OQUDI at 14000 ft; the procedure turn entry and turn inbound distance is insufficient to descend to 11000 ft. at OQUDI inbound as published. As depicted; we mistakenly assumed we could make a left turn and descend to cross at 11000 ft. inbound. When we tried to enter the hold; the aircraft turned right; which is the holding pattern at OQUDI for the missed approach procedure for the RNAV 13. We remained at 14000 ft. due to terrain and not being on a published segment of the approach. Contacted ABQ Center; explained what had happened; and we were recleared for the RNAV 13. Normal approach and landing. Would recommend joining the approach from TELOY. The MEA from TELOY to OQUDI is 11000 ft. and eliminates the need for a 3000 foot descent in a short distance. Commences the approach in a more stabilized fashion. Beware of multiple procedures (procedure turn and hold) that share a common fix.
Second reporter narrative
Coming into Taos Regional from the southeast; we were given 14;000 ft. direct OQUDI for the RNAV 13 approach. We were cleared to cross OQUDI at or above 11;000 ft. and cleared to change to Taos CTAF/UNICOM. The Captain flew a parallel entry coupled with the FMS and autopilot and requested one lap in the holding pattern to continue descent to 11;000 ft. The FMS indicated Exiting Hold but did not show a Resume Hold button. I stated this to the Captain and asked if he would like me to add a hold back onto OQUDI. He said yes; and I added the Hold from patterns. This had the same inbound course of 168 degrees; but I realized afterwards indicated a right holding pattern instead of the published left (I believe it added the missed approach holding pattern). We agreed to stay at 14;000 ft. and not descend until the hold was corrected via heading mode. I returned to Albuquerque Center and communicated our intentions. Once in the left holding pattern; the captain descended to 11;000 ft. and proceeded with a stable and uneventful approach and landing.Cause: False expectations from the crew on how the FMS would execute the approach given direct OQUDI from the southeast.Suggestions: Request TELOY if given direct OQUDI allows more time to descend and get established while avoiding terrain and noise abatement areas. Greater familiarization and attention to detail with the FMS.
