RVR Take off Mins

Ok. Using a Jepp chart it's easy to determine which runway(s) have RVR and the lowest RVR you can use for that runway (OpSpec allowing)


How do you do this using NOAA charts and an AFD? My OpSpec allows for 600 RVR takeoff with CL and HIRL (boiler plate stuff).

KRST for example allows for 500 RVR (I'm still limited to 600 RVR) but I can't find that info using "government" sources.

It all may be moot as I don't know of any RVR equipped runway that has CL and HIRL that has higher than 600 RVR takeoff mins.

If it's not listed then I believe it goes to the lowest you are allowed. I'm on my phone but try looking it up in the instrument procedures handbook.

That's the thing. RVR is an OpSpec thing that requires certain equipment on the runway, CL, HIRL, etc. On Jepp 10-9 that stuff is shown in one location, min RVR value and runway equipement. On the NOAA stuff I can only find the runway equipment no mention anywhere of min RVR value. I'm thinking that Jepp shows it for convenience BUT, I wonder if there is an airport out there that is still a 600 RVR runway with CL and HIRL. It seems most now are 500 RVR and I think 500 RVR is fairly common in the airlines per OpSpec. Maybe not.

Don't use NACO charts. That's all I really have for that.

I'm pretty sure they show it for convenience as well...and some places DO have non-standard takeoff minima. The Jepp format is trivial to read and highly convenient. I couldn't even begin to point it out to you in the NACO books.

Our OpsSpecs (see C078) authorize us to use lower than standard anywhere standard takeoff mins are authorized, down to 600 RVR, with various equipment installed and operative. I seem to remember that FDX has approval for RVR 5-5-5, but most of the rest of us (including my airline, as amended on 12 May 2008) are limited to 6-6-6.

The government says that it will not be listed if it is standard and talks about it being in the ops specs for how reduced minima should be applied. Much like what @Autothrust Blue said.

My 121 didn't have reduced minima because we rarely had visibility on the ground less than a mile so I am unfamiliar with the wording.
