With modern engines, failure rate is way lower than the historical norm.

IMO-it will be the easiest way for me to be comfortable operating out of short rwys. In the past, that comfort level was provided my knowing my predicted stop margin

There is so much wrong with this post I don't even know where to start. I've never seen a crew force get so puckered up about stop margin. If it's zero......you're still fine. Any hi-speed reject is going to be a serious situation. We have to obviously be on our game with less of a stop margin but why do we trust performance numbers in other situations but not when it comes to takeoff stop margin?
If the data says you've got less than 500' it's as if guys don't want to go. And off loading freight to get more runway is completely ridiculous. Other airlines don't give you stop margin. They deal with required runway length. If you're good....you're good.

I say the same about your post.

We use stop margin for one thing: whether to choose another runway or not.

I've never seen a pilot refuse a takeoff because of a small stop margin. I've seen plenty of 777 takeoffs that had a stop margin of less than 250 '.

The stop margin is a tool to see whether the closer runway is acceptable, or whether we need to taxi to a longer runway.

If you take off with a tiny stop margin on a shorter runway (or with a tailwind), when you could have taxied a little longer to a better stop margin, and something happens and you screw up an abort, get ready. NONE of this pressure to use the closest runway is in writing. It's all verbal. It'll just be you sitting at the table, explaining why you decided to not use the big runway. The one that Fred Smith paid for (36C), so we could use it......

Sitting here reading this thread and I'd like to ask my FedEx Bro's a question. What is the "DG Inspection" that you perform prior to flight? At UPS we get a NOTOC form telling us what and where the DG is, but I've never inspected it. Unless I have reason to question the paperwork. Do you guys actually inspect it?
just curious.

The FO is req'd to inspect to make sure it's not leaking/stinking.....like some of our older Captains:D:D

Just to clarify, we only inspect DG's
that are accessible, and not every type DG warrants an inspection.

Interesting, thanks for the information. All our cans are closed so there really is no way to do this unless they stop loading and let you look into the can. Even then I wouldn't know what I'm supposed to be looking for other than obvious leaks or damage.

Pax airlines routinely operate at what we call LMTOGW (others have different names for it)-much more so than we do as we tend to bulk out first.

I agree with you Huck. Knowing the stop margin is another piece of the puzzle that I'd like to have. Just might make a difference whether I reject at V1 or not. And, with a small margin, if the wind swings around or the brakes aren't quite as new as they might be, it would be good info to have. I think to NOT have stop margin information when it's easily available is bad headwork.

While I'm a fan of "data" I think this is becoming one more red herring thrown out there. I believe all major US carriers DON'T provide stop margin data to their crews. I have not seen or heard of a lot of HIGH speed rejects here or even at other airlines. I have heard of a few low speed rejects and most of these have been just after setting T/O power and are more of the "pull it back to idle" and talk about it variety.



I'm sure somebody will provide some examples of high speed rejects. But can we honestly say they are a problem here?

Lots of chaff and flares being tossed out there, not all intended to distract us, but in any case it is.

You bring up a good point, but there is a legality issue here. Data for runway 18 with wind 270/15 shows we're good to go, stop margin unknown. FDX 1234 wind 290/15 cleared for takeoff. Are we legal without re computing the data? If I had known I have a 3000 ft stop margin I could use a reasonably experienced guess and know I'm safe. But if the stop margin was zero and now introducing some tailwind, I couldn't take off. What's my choice if I don't have that info?

Please, at or after V1, do not ever contemplate that.
