Is the 757 overpowered
« on: December 09, 2005, 09:04:05 PM »
From recent flights on 757s and asking pilots at the AA maintenence facility at AFW I think the 757's engines might be to powerful for the aircraft


listen  2 the engine noise

Define "too powerful".

I personally think the 757 is "nicely powered".

Part of designing an over-water, twin engine aircraft has to be consideration given to extended signle engine flight.

With that in mind, a lot of power seems pretty reasonable, especially for an aircraft that regularly spends many hours over arctic nothingness.

One other thing to consider is with very powerfull engines, while cruising at alt they are running at very low power settings there by being more fuel efficient.

Is that like a "girl too sexy"?

A great thing about an "overpowered" aircraft is single engine climb capability when you lose an engine on takeoff.  This gives a much improved margin of safety in one of the most critical phases of flight.

The fact that the 757 is out of production is also relevant to the discussion.

Too bad.. only thing it really needs is the modern engines and it'd be still popular.
Otherwise its only problem is the turbulence category of heavy, for a medium size plane.

IIRC turbines are in their most efficient use when running close to the max rpm (fuel usage vs thrust) or at least they were 10 years ago.
