Approach Question

If the published mins don't include RVR, then I don't see how you could use it. You'd need 1/2 a mile and you only have 1/8th.
 
Probably not, reason being any runway that's equiped with an RVR will have the mins stated in RVR. Since the airport is showing 1/8 mile vis, use that for everything but the specific runway.

I guess we all assumed texaspilot was giving us the RVR for the specific runway he was landing on. If not, and the RVR report was for a different runway, then yes I would agree with the above.
 
Possible that I missed something but if it is reporting 100 OVC and mins are 250 then I do not see how you begin the approach, unless you have received this wx report after passing your fap.

250 would just be a DA. You can shoot the approach if the clouds are reported to be lower than the DA, vis is the only wx requirement that must be met.

EDIT: Just to be sure, I think we're all also assuming texaspilot is asking the question in a 121/135 environment, not 91. Obviously all bets are off if it's 91.

That is what is reported...YOucan always shoot the approach and 'look for the lights'.....
 
Looking at it in the 135 regs under 135.225 (2) "the latest weather report issued by that weather reporting facility indicates that weather conditions are at or above the authorzed IFR landing minimums for that airport."

Not disagreeing, I just do not see where it says that only visibility is controlling and not your lowest ceiling. I'd appreciate it if you could point me in the right direction. Thinking that you are referencing 91.175 Takeoff and landing under IFR. Thanks for the help.
 
After I posted the last one I turned on the brain and started thinking. You are correct 135.225 mentions airport minimums, not approach minimums. Thanks for clarifying.
 
Well....I shot the approach. The runway I ended up shooting the approach to had RVR and the reg's for that runway were 200/24. But I had to do it with a 14 knot tailwind.

Just wondering what would have been "legal" if i wanted to shoot an approach to a runway with a headwind but no rvr and visibility of 1/2 req'd.

Nice kick in the but after not having to shoot more than prolly 4 approaches in the last 2 months.

Does your airplane have a tailwind limitation? Many large airplanes have a 10 kt limitation, mainly due to the fact that landing distance only has to be calculated with up to a 10 kt tailwind for certification.
 
RVR is runway specific. The 2400 at the runway you landed on doesn't count for the opposite end. That one you had to use prevailing vis of 1/8 of a mile and was below mins, so you were right to not use it. The 14 knot tailwind would be illegal in the transport catagory jets I've flown. You'd have to check the limitations for your aircraft.

I guess your ops specs could be different, I'm just going off the top of my head. Where's Seagull or Midlife when you need them.

Also, I believe part 91 still has to observe landing minimums to land, though you can shoot the aproach regardless of the weather, unlike 135/121. There are no takeoff mins, though, under 91. You can go zero/zero.

Ceiling isn't an issue except in forcasts or very rare cases where it's mentioned on the approach chart.
