Not much point in asking for a wind check or using on board displays if you just end up ignoring them and landing anyway.
Asking for a wind check, finding out it’s a tailwind and then continuing? That’s not ignoring. That’s getting data. Once you get outside of the US, a lot of airports are one way in, one way out. Sometimes this is due to terrain or lack of an Insteument approach, restricted areas or weather. My home airport regularly has a 20-40 kt tailwind, transitioning to a 10-15 kt headwind below 1000’ agl, a lot of terrain and thermals. Also, there are hostile neighbors on 2 sides. Thanks for your flight instructor expertise though Maverick.

I think we were okay.
Ok – no set tailwind limit. My bad. I assumed you were operating a 121 jet. Got it. Sounds like you’re not flying 121.
Every one of the transport category jets I’ve flown (4 Boeings, 2 Airbus and the MD-11) all have specific tailwind and crosswind limits in the flight manual (some even have headwind limits in the case of autoland). So, that’s where it’s prohibited for operators of those aircraft. 777 tailwind limit is 15 knots. For you, I guess there is no limit other than what your landing data calculations provide. Maybe you don’t calculate landing data – sounds like you just decide after you land if you were okay by what taxiway you make. To each his own.

We don’t have the option to say – “Meh… made the same turn-off as I usually do, so we’re fine.” If the winds are out of limits, we don’t land.
Someone wants a wind check, have at it. Personally, I’ve always taken them with a grain of salt. Flying into our old Asia hub in Subic Bay, the tower was notorious for giving us the winds we “needed” to land in the preferred direction. Luckily, we have an on-board display that I find far more helpful than what the tower is calling. If it’s showing an out of limits tailwind when I get over the numbers, then it’s time to go around regardless of what the tower is telling me.

Oh.. wow. Tell me more about this "outside the US" you speak of. And "hostile neighbors".... I think I peed myself a little just typing it.

Look you clown. If your company allows you to ignore manufacturer flight manual ops limits and do whatever you want, then have at it. I don't have that option nor did any other 121 airlines I worked for.

Regardless of thermals or tailwinds that turn to headwinds - If I'm looking at more than a 15 knot tailwind when I cross the threshold, I'm not allowed to land. I value my job, my license and the safety of our crew far more than being able to come on to APC and try to impress everyone with my war stories of crazy winds and scary neighbors. I'm not interested in comparing war stories from another life. Now I get stuff from A to B safely while complying with the restrictions my employer and aircraft manufacturer have imposed on me.

It’s abundantly clear that posting on the “tool of the day” thread is an automatic entry into that same category. Regretfully, I have now posted on this thread.....but it was worth it to make a VERY valid point.

One might reasonably conclude that for an airplane which normally lands at 70 knots with a 1200 ft rollout (and for which no tailwind limit exists) a 9000-10,000 ft runway is essentially unlimited. It's obvious he's not flying 121 jets, why try to insist he should be complying with 121 regulations and jet procedures?

Hence my acknowledgment of that and my bad assumption. Not insisting he do anything of the sort.

Oh really? You need to review your post, even after acknowledging that he probably wasn't flying 121, you still continued on to make your snotty, condescending comments about not calculating landing distance and assuming it was ok after the fact.

Are you really trying to claim that this:

sounds like you just decide after you land if you were okay by what taxiway you make. To each his own.
wasn't intended to be denigrating and a backhanded way of implying that he should be doing performance calculations. ?

TOTD goes to the guy in an RV4 that was doing his run up ON THE RUNWAY and made us go around.

Apparently he hadn’t read the NOTAMS since 2016 and missed the fact that the hold short lines were pushed back and was no longer the “safety area” he still insisted existed.

Okay - valid critique. Bad assumption on my part with a worse delivery.
