The burn should be compared to B727 not to A310/320. Different generation. Tops B727, not by much, but is also bigger and faster. I heard stories of .92-.95. I don't how much truth in that. However B727 can reach .88

Quick search shows Max cruise speed 527KTS
Econ Speed 486KTS
Not bad for a late 60's east block 727 I guess....
That will give the 747 boys something to think about!

Yep, but the Bulgarian ones I've seen whizzing around seem to do that kind of speed at 3000'!
Well, maybe a slight exageration, but they went past us doing 290kts at a good rate!

Moscow-SVO Noise Abatement Procedures
I love walking on the ramp to customs and watching a TU-134/154 depart. It sounds like an F-4. Yet when we arrive, we have to brief that we are only permitted to use idle-reverse for noise considerations (unless safety dictates otherwise).

Well, according to Aviadvigatel's website, sound like PS-90 burns roughly 1800kg/hr at cruise or around 4000lb/hr.

Used to fly Tupolev154
En cruise she goes at M0.82
MAX TU154M M0.85
TU154B 0.88(older version guzzling 6 tons/hour)
TU 204 with PS-90 engines roughly 3.5 t/h, but it's quite slow M.72-78
TU154M is a nice and very reliable aicraft. Onboad flight control computer (enhancing hydromechanical flight control ) is from some rocket.
But it's very easy to do a hard landing - without engine power it nicely goes down! Whet it's hot and high we used to add some RPM (up to climb power
when it's heavy) during flare, and then set idle.
