Dash 8. question

[blueg33]

I often fly from Birmingham to Glasgow with Flybe on their Dash 8 400.

I have noticed that they always taxi with only the starboard engine running. I would have expected them to alternate so that both engines have done similar hours running. They only start the port engine on the runway threshold and shut in down as soon as they are on the taxiway after landing.

Why don't they alternate?

[Taita]

Maybe coming the other way they use the other one

[RCBRG]

its likely to do with running the engine on the opposite side to the stand, boarding operation etc

I flew on one of these for first time to Newquay Manchester a few weeks ago. Actually found the acceleration on takeoff really strong, loved it! Much better than a fully loaded 747 etc!

I'd always like to be a on a 100% thrust, empty airliner on takeoff - should be rapid! Anyone know what the most 'over powered' airliner is?

Is it that number 2 powers more systems than 1 does (hydraulic power to the brakes, for example). I know that on the 747 number 4 powers the brakes and number 3 can be, and often is, shut down on taxi.

[RCBRG]

on aircraft like the ATR the right hand engine is used as an APU, with the engine at a low idle and the prop stopped.

Divide total engine thrust by operational empty weight for your answer. Don't know what the current champ is but the 757 was pretty impressive in its day. These days with flex power takeoffs for economicals, it's rare to see a full capability take off in action outside of an airshow.

I think the vc10 was known to be over powered, as I belive it was designed for the empire: hot, humid runways which might not be long enough...

An empty B777 freighter climbs pretty rapidly, recently managed 0-40,000' in ten minutes :-)

TU-154 climbs well (Looks and sounds bloody brilliant aswell)

747 SP?

I'm with Rubymuarry on this one. We did from engine start to 41,000ft in 14mins, empty with 26 tons of fuel in order to meet min landing weight getting out of what is a war zone.
Shame the company doesn't share the same view as its pilots.
The acceleration is akin to a 911 turbo but goes on well past 150mph

I'd go with the 757.

JWH is your man for this question. I think other posters are likely to be correct when they say that certain systems are probably desired that are powered by the No.2 engine. I doubt it is to do with the location of the engine relative to things on the ground, as some aircraft types start No.1 first and then taxi out single-engine.

[DangerMonkey]

In any case it's desireable to have a good split on hours between the engines

Empty MD11 out of Manston to Ostende is pretty exciting especially with an obliging crew (max power take off via a maintenance request)
