Narrative:

We stayed offshore to avoid thunderstorms on the arrival. About 20 miles out from the airport we proceeded to DME 8.5 on the approach course to avoid thunderstorms over bemuv. We shot the localizer runway 5 approach because the glideslope was not available due to the dthr for runway 5. We were not able to acquire the displaced runway threshold (dthr) marking until 2.5 miles out on the approach. The runway marking isn't wide enough and has almost no contrast to the surrounding runway surface. The marking for the dthr is about 200 ft northeast of taxiway B. My local knowledge of where the dthr was made the difference in continuing the approach. We departed at dusk with the runway lights on and the dthr was clearly marked. The lack of approach lighting and an almost invisible dthr would result in a missed approach in IFR weather conditions.

Title: Air carrier pilot reported difficulty identifying the MUHG Runway 5 displaced threshold because of the prevailing visibility; the runway marking width; the low contrast from the surrounding runway surface; and no approach lights.

Narrative: We stayed offshore to avoid thunderstorms on the arrival. About 20 miles out from the airport we proceeded to DME 8.5 on the approach course to avoid thunderstorms over BEMUV. We shot the LOC Runway 5 approach because the glideslope was not available due to the DTHR for Runway 5. We were not able to acquire the displaced runway threshold (DTHR) marking until 2.5 miles out on the approach. The runway marking isn't wide enough and has almost no contrast to the surrounding runway surface. The marking for the DTHR is about 200 ft northeast of Taxiway B.
