I've never heard that. Do they "run up" one or two engines at a time, or do all of them run up at once? The latter would put an enormous strain on the brakes, I assume. I don't even know why a jet run-up would be necessary. I'm curious as well.

I've seen in-cockpit footage of an AN-225 taking off and the pilots applies FULL power to all 6 engines at once. The jetblast behind is very severe and would probably damage a plane lined up behind it.

In my enthusiastic passenger experience, I took off from O'Hare 31R enroute San Francisco, and we applied full throttle before rolling (UA 747-200). Coming back, the pilot flying a UA 747-400 decided to take off to the north, whatever runway that is, though I know it's comparitavely short, and we pretty much made a casual takeoff without any rnwy run-up. In conclusion, I don't know why they do or don't do it.
