Ethics Gradient
CAP 168 states that when when IRVR is not available, manual RVR is permitted for CAT 1 approaches only. CAT 2 and 3 not available.
REF CAP168 Appendix 2A page 1.
The airport Authority on this night had to remove CAT 2/3 capability and NOTAM such action.
You could then have made a CAT 1 approach, but then under 'Absolute Minima' rules, if the manual RVR was less than 550m we would have filed a report on your flight!
I've had this before where JAR and CAA do not tie up. LVPs is a bollocks at the best of times......so easy to get it wrong....
