The average fuel burn of Tu-154M is 5.5 tons/hour.

Ouch! :ouch:
That's against the 320/321 burn of about 2-2.2 tonnes an hour!
Gotta love the Tupolev Ground Grippers!

Yeah, but its bloody quick, and looks far cooler than an airbus :ok:

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!

A cute feature of Tu-154 is 12 main wheels. B727 has just 4, and they are very heavily loaded (737 and 320 are lighter, while the bigger planes have 8 or more wheels).

I've thought about it, and that's about the same speed as a 747.

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!
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).

But if we compare to Tu-204 or Tu-214 (bigger), how much does they burns?

I imagine that the RB211-powered 204 burns something similar to an RB211-powered 757.

Yes, I think it will be something like the 757. But the most intresting is the PS-90 version:)

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

Of course these numbers are per engines!!!!
If they were not i guess Tupolev may have made a succes in airplane building
wich is quite surpricing :E

Yes, per engine, per hour.

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.
