RVR
Please can someone explain the following. At Durham Tees Valley Airport, KLM F70 Aircraft require 550 metres RVR (Runway Visual Range) when landing on Runway 23, whereas when landing on Runway 05 an RVR of 750 metres is required. What are the factors which go to make up such a difference.
Thanks.
Thanks.

23 has 777m of HI approach lighting whilst 05 only has 605m. Cat 1 (absolute minima 550m RVR) requires a minimum of 730m hence 23 is Cat 1 and 05 isn't.

Technically, they are both Cat I. It's just that the standard lowest minima (we will not consider LTS) are 550 M RVR and 200 feet above threshold, typically expressed as an altitude.
Mike Tee: It's not just KLM Fokker 70 aircraft that fly with those minima. All users are bound by the same restrictions.
