Can anyone give me a hint, which part of the 3 RVR values(tchdown, mid, end) is the one to be considered? Exmpl. 550 400 300

Must all of them be above the minimum?

Thx

First of all, I take it you're only CAT I approved? What I can tell you from my company's CAT3A LVP requirements are as follows:

T/O: 90m initial segment (pilot's observation) otherwise start125, Mid125, End125. End point RVR can be discounted subject to rejected take off/runway length.

Landing: 200m, Mid125, End125. End point RVR can be discounted subject to LDR.

There are some other approach minima criteria that can be placed and/or eased after status has been achieved.

swordsman, I'm just wondering how long it will take the "Thread Police" to arrive and move this thread to another forum; then again maybe not. :E

I assume you talk about CAT 1 minima.
They are 550,125,75.
Last two only relevant when applicable. E.G. speed still above 60kts.

sky captain, I believe the term is now CMV (converted Met Viz) :confused:

request visual, I believe the Mid and End reporting points have to be above the LVP T/O minima if one has passed the outer marker/equivalent position whilst the touchdown RVR has suddenly dropped below 550. This I know to be true for CAT3A. Does this apply to CAT1? I ain't gotta clue.

NSR & SC,

CMV does not apply to CAT II/III, ennit? ;)

@No speed restriction
Those figures are straight out of the EU OPS for CAT1 approaches.

The meaning was for RVR landing report, as it for the jar ops requierments(Europe).

The question is reffering to all the values at or above the minimums(all categories)or alternatively, can one or two values be less than the minimum for the specific approach?

in which case the end point can be 0 subject LDR.
