Your Sunday Morning Jet Noise


A long time ago, I was told that one of the idiosyncrasies of those Progress engines is that they have to be brought up to power slowly to avoid overspeeding. Which is apparently why you'll see that An-225 and An-124s sitting at the end of the runway, running their engines up before departing.

No doubt that ATC loves that all to pieces.

There is quite a bit of discussion on the long runway spool up, but very little data from pilots who have actually flown the 124's. It seems most plausible that it is a response to several accidents due to engines not producing rated power due to engines at less than operating temperature having excessive fan blade clearance.

Yep, I've seen the same thing with the 124s in San Diego. I think it has to do with the lack of governors, and the need for max thrust matched across the engines.
