Narrative:

We were reassigned flight to mroc. I had been to mroc two times previously and the first officer once before. We were expecting the ILS 07 with light winds from the west. Due to terrain east of mroc runway 07 is preferred. There is not a straight in approach for runway 25. Upon check in with coco approach we were issued a clearance for the ILS 07 circle to land 25. There is a visual approach for runway 25 (cyrus visual runway 25) and it is line selectable as [RNAV 25]. This runway assignment was given with little time to install the approach; get new landing data for the runway; and brief the new approach all while continuing to comply with the altitude constraints of the STAR. This was all done and I briefed that we would expect to be configured for final at epabe since the turn to final put you on a very short final. After touchdown the ACARS printed out an information report that stated that our average flap setting below 1;000 feet was 14. After looking more closely at the approach I noticed that the altitude from tomas (on the fiora STAR) to epabe was 4;000 feet. The airport elevation at mroc is 3;021. This placed us below 1;000 feet for approximately 20 miles.

Title: A Captain reported that while complying with an ILS circle to land approach clearance at MROC that the aircraft was below 1;000 feet AGL for approximately 20 miles.

Narrative: We were reassigned flight to MROC. I had been to MROC two times previously and the First Officer once before. We were expecting the ILS 07 with light winds from the west. Due to terrain east of MROC runway 07 is preferred. There is not a straight in approach for runway 25. Upon check in with COCO approach we were issued a clearance for the ILS 07 circle to land 25. There is a visual approach for runway 25 (Cyrus Visual RWY 25) and it is line selectable as [RNAV 25]. This runway assignment was given with little time to install the approach; get new landing data for the runway; and brief the new approach all while continuing to comply with the altitude constraints of the STAR. This was all done and I briefed that we would expect to be configured for final at EPABE since the turn to final put you on a very short final. After touchdown the ACARS printed out an information report that stated that our average flap setting below 1;000 feet was 14. After looking more closely at the approach I noticed that the altitude from Tomas (on the Fiora STAR) to EPABE was 4;000 feet. The airport elevation at MROC is 3;021. This placed us below 1;000 feet for approximately 20 miles.
