I know the Saab 340 isn't on your list, but I hit the timer as soon as we're cleared for T/O. The gear locks up at about 50 seconds, usually.

FWIW....

You forgot to put the 727 on your list too....

Takeoff roll is about 13 minutes...give or take, depending on how hot it is.

Is a room temperature 727 hot or is it tepid?

Gross weight affects roll a LOT in the 737, and probably many of the other jets named. Take a lightweight -700, with a good headwind, and a max thrust takeoff (not the norm, but there are various reasons you'd do a max thrust takeoff even when performance-wise you could derate it a lot), you're up & away in a couple thousand feet or less. On the other hand, same jet but full of folks & bags & gas in a hot, still day in Vegas or ABQ or SLC, it'll roll for a long, long time.

I guess you could define some "average" gross weight (though average weight leaving LAX heading to Chicago is going to be a lot higher than LAX to LAS), an "average" temperature and winds for whatever airfield you're interested in, and an "average" derated thrust, and that would give you a number of seconds for takeoff roll, but you change any of those parameters, your answer will change too.

Interestingly, longer runways will tend to produce longer takeoff rolls than shorter runways... when you have the extra distance to accelerate, you can go with a greater derate & still meet all your runway & climb limts. On a short runway, using derated thrust (and "improved climb" profile) may be no option, so you use max thrust & rotate sooner.

(Takeoff roll also seems to happen exponentially faster the newer you are to a particular jet, but that's a different dynamic at work!)

Can anyone tell me how many rivets each of these planes has?

Widgeon, you beat me to it. Except that I was going to say about a day and a half...

 

[Resocha]

I don't know the average takeoff time in the 747. But the other day I took from HNL in a -300 at 732,000 pounds. The takeoff report showed a time of 49 seconds from when 1.2 EPR was reached until 48 feet RA.

It's going to be longer on longer runways and shorter on shorter runways.
