Hi,

Different airports are marked slightly differently. What is your tip to determine the last 2000ft of usable runway given that there are no signs stating how much runway is left?

Thanks

Runway edge lights change color to yellow in the last 2000 feet (FAA) or 600m for EASA/ICAO. Additionally, on an FAA runway the far end of the first set of of the two double-striped distance markers painted on the surface of a precision runway (on either side of the centerline) would indicate 2000 feet remaining. ICAO runways should only have one set of double striped touchdown zone markings and the ends of these markers closest to the far end of the runway indicates 600 m remain. EASA runways only have solid distance markings in which case the touchdown markings just prior to the thick 400m aiming point markers would indicate 2000ft/600m remaining.

What's an EASA runway, then?

Runways without distance coding, bottom left picture in my previous post. This seems to be the runway used at most European airports versus the runway with distance coding used more often in Asia. I'm sure there are exceptions.

The markings described above at the opposite runway end do give a good indication that you are approaching the end of the runway. If the landing threshold at the opposite end is displaced then these markings will be further back from the runway end so the distance remaining is more depending on the amount of threshold displacement. If the runway has centreline lights then they should be colour coded 900m from the end i.e between 900m and 300m alternate red/white and the remaining 300m all red.
