"All Pilots must ensure that a meterological visibility to RVR/CMV conversion is not used for:
• Takeoff
• For calculating any other required RVR minimum less than 800m,
• Or when reported RVR is available"
So basically I can always convert my VIS if it will give me an RVR of at least 800m.
So at night, with high app lights, and a VIS of 400 m, gives me an RVR of 800m.
Good to go?
These are all obviously cat 1 approaches.
Are cat 2/3 also complicated?
Haven't gotten there just yet
