You may be right (I honestly can’t remember as the one time I did it, we got a WS warning and did the recovery instead) but I would imagine taking off the 19s in SFO is extremely rare. I’ve only done it once and it was max power on a 75….and a fuel stop in SLC….and a 42kt HW required on the WDR😳

could be true, I’ve never taken off southbound

The times I've looked at it, it was less than 5 degrees assumed temperature. I did line up and wait on a line check and then got the dreaded winds are "XXX@X cleared for takeoff." Told the FO to say we can't accept a tailwind and that we would taxi clear to get new performance numbers. Check airman asked why I was taxing clear and once past the hold short we all had a chat about it. It took about 10 minutes with 2 running to get numbers, program, verify, redo checklist, explain to FAs and PAX, get back in line and go.

Exactly…..in my opinion, one of the best changes in flight ops was John Laugher taking over. While I don’t think he changed the culture directly, he empowered those that did.

Before John, we had such winners as:

50 taxi out without flaps extended events a week.

A CQ that drilled in the effect of latency and the very next module telling us to slow the operation for “safety”. DO NOT delay taxi to interrogate the WDR.

Pushback while doing other tasks.

Luckily the culture of my base/fleet is generally not interrogating the WDR while moving. It’s either before push or after with the brakes set. Only when unavailable before taxi is it done independently.

The taxi check is typically done during the taxi but if the crew wants to do it early, who cares.

The culture of rushing left with Dixon and Graham. Safety above speed.

now do it on a 7500’ runway


and that’s ignoring the fact that neither of us know the actual cost of a fleet wide change in assumed temperature.

NADP1... for more fun. The M88 NADP 1 with T/O power was a highest pitch attitude I've ever had on a passenger jet. I was in steerage looking down the tube once and watched every aisle passenger grab the armrest simultaneously.

I think it's about more than cost. The change seemed to happen when PAX weights were increased. High deck angles are uncomfortable for PAX, noise is more of an issue now days, and the time factor when changes are needed hasen't been studied. I'll do it however Delta directs me to do it but I see the changes as immaterial so long as crews are aware and not in a hurry. You really have to listen for the winds with the T/O clearance and do some quick mental math or have an idea of the tail wind component when you take the runway. IMHO not making tailwind accomodations sets us up for failure, at least when the wind direction is close to 90 degrees off. YMMV

What?! Aren't these the same passengers that want to recline their seats? Personally, I would rather pitch up and fly V2+10 to gain altitude after takeoff than try to pander so some myth that passengers don't like high deck angles during takeoff. The passenger that doesn't like pitching up to 18 degrees probably doesn't like it when we bank to 30 degrees either.

I'm not saying you're wrong, but... back when I was a commuter on the mighty dog I got a lot of questions about why.

Perfectly said.
