I think it's safe to assume that if you can see that the lights are working then they're working.
Yes you can measure 90m with Barrett's but they still don't meet the 15m spacing requirement do they?
and when did I say you you could go without relevant RVR's
Where are the the RVRs reported? TDZ, MID, STOPEND. Wheres your RVR report for the displaced threshold?
