Dear All,
I am looking for examples of airports where a runway has an exit taxiway that is beyond the end of runway markings and runway end lights. It seems that at some airports, landing aircraft are able to roll through the end of runway lights in order to use that exit. Of course the relevant declared distances are only declared to the end of runway markings, and not beyond. ICAO Annex 14 and EASA do not make explicit statements on this issue.
Annex 14 seemingly makes allowances for this, because there are two possible patterns for the red runway end lights, either:
a) equally spaced between the rows of runway edge lights; or
b) symmetrically disposed about the runway centre line in two groups with the lights uniformly spaced in each group and with a gap between the groups of not more than half the distance between the rows of runway edge lights.
Application of pattern (a) would present to the pilots a pattern almost like a stop bar, so the message is clear - do not proceed. However, with pattern (b), there would be a gap in the middle of the runway end light pattern, which may appear to present an opportunity to taxi through.
Do you know of any examples where this happens?
Thanks!
