If your'e doing a 30 second pre-takeoff run for nacelle thermal anti-ice, where else do you do that run? That thirty second run to warm the nacelles is best done just prior to brake release, and should be coordinated with the tower. There is no indication of a run-up requested or done here, however.

No such request was heard on the audio, and a crew would not/should not do a run on the runway without clearing that with the tower, first.

It's clear that the southwest flight shouldn't have been released with the FedEx flight on a Cat III. It sounds, from the audio, like ATC was pushing runway utilization as tight as they could, which is setting up for something like this to occur.

A call from an airplane going around should not be to the aircraft taking off to abort (reject: it's a Boeing). That's not a call to be made by the aircraft initiating a missed approach, and certainly not a call I'm aware of any training department or organization using as a standard. The only person who should have called to reject the takeoff with Southwest is one of two in the cockpit; otherwise the tower controller might have cancelled clearance, but certainly should not call for an "abort." The pilot of the FedEx airplane shouldn't be calling "abort," either. Fly the airplane you're in, not the other guy's aircraft.

Better to go missed earlier than later, in this case, and they did.

Poor SA and ADM by the WN crew. They requested — and then accepted!!!— the takeoff clearance. Glad I’m not that CA. He/She will be in some VERY hot water for this.

You obviously haven’t RTFT…..

​​​​​……..no reason to quote me in one of your typical all knowing/omniscient diatribes…..

Also, good job on being Judgy McJudgerstein on the FedEx crews actions, well done sir!!!!!

I don't know what "RTFT" is, as I don't speak rubber-bone teenager, but I quoted you because you said something stupid, which merited comment. If you don't wish to be quoted speaking stupidity, then grow a brain or remain silent.

Actually, the poster making the comment asking if they were doing an engine run seemed like he said “something stupid”, but, whatever….

And maybe take some of your own advice?

Tell you one thing. Push them up together when the pavement’s not dry.

Or you could say "mark tape"

There was one trigger for them. I’ve refused a takeoff clearance when it’s ifr and someone is on the approach. They were told about the heavy. I do not think they delayed on the runway. Takeoff if those conditions can take a minute.

I agree. The hold short line is a quite a ways back from the actual runway.

Sounds like a couple of people asleep at the wheel, FedEx not being one of them.
SouthWest should have never been given a clearance and they should have not accepted one either.
As far as the ‘abort’ call, what’s next? Blaming FedEx for not initiating a go-around earlier?
I find it somewhat curious how laid back the TWR controller sounds through all of this.
