I saw an aviation TV program recently in the which the presenter, who is also a 757 First Officer, expressed the opinion that the 757 is the most over powered airliner in the sky. If this is so, why the excess power? Was it due to commonality requirements with the 767? And does it make the 757 a fun plane to fly, or lead to problems if you are unfamiliar with it?
Incidentally, the presenter is also lead singer with a heavy metal band: what a life some people have!

I had the chance to fly a RG 757 (PP-VTS) on its "test flight" on GIG.
We rolled out of VEM (Varig Engineering and Maintenance) hangar and headed to RW28. Just to feel the power, the pilot selected full thrust for takeoff and I can just say: WOOOW. I felt pasted to the seat and we reached FL120 in under 3 minutes.
It's a great plane and a shame that Boeing quit its producion.

"Overpowered" is a relative term. AA's 757s are "overpowered" for most North American flights, but are hardly "overpowered" for South American flights...especially the "high altitude" airports. Certainly as used by AA, the MD90 was considerably more "overpowered" than AA's 757.

The 757 (with RB211 535E4 engines) is not overpowered. The 757=200 variants have GTOW's ranging from 104 K kg to 114 k kg. At the lighter non-ETOPS weights, it PERFORMS. At the heavier weights, you don't want to lose an engine, especially at high density altitudes.
Tail strikes are a non-issue as they are largely a product of technique.

I was jumpseating once on a B757PF and we did a go-around from abour 10 feet RA (runway incursion). In my humble opinion, any full aircraft that can do a GA from 10ft, and never touch the ground, has a whole lot of power.

The problem with comparing thrust-to-weight ratios is you have to know what weight to use. This is really a continuation of AAR90's thoughts. If you use the MTOW, the question is how often is a 757 at or near MTOW compared to other aircraft. From what I've seen, it's hard to get a 757 anywhere near its MTOW on a short/medium flight. So basing a T/W comparison on MTOW vs. basing it on what you're likely to see day-in/day-out for each aircraft type will give different answers. I have no way of measuring how often 757 is near MTOW compared to other aircraft, but I'd guess it's a lot less frequent.
It's probably not over-powered at all if you're a UK charter airline stuffing way too many people in flying anywhere further than LEXX, or CO flying it trans-Atlantic, or anyone flying it west coast to Hawaii... but for ATL-RSW in a two-class layout, that's another story.
BTW, it's my all-time favorite aircraft, so by no means am I bashing it.

Dunno about over-powered because its the only airliner I have flown so have nothing to compare it to but........makes performance planning out of poxy Greek airfields fairly easy, no need to worry about off-loading bags or stuff like that, you just go!
PS,last ferry flight, FL410 in 17 minutes using all the derates!
Depending on engine choice, the 757 comes in at about 2.93. There are many variables I haven't gotten into, but the general comparisons remain about the same. In the end, bizjet performance is quite impressive.

If its so over powered then why do the 757's on the trans atlantic routes only make it to FL280?
I guess I must have dreamed working all those CO's 757's flying in the mid and high thirties on the Atlantic crossing The only reason a 757 would be limited to F280 on the crossing would be due to a lack of MNPS/RVSM certification.

Wouldn't it be better to have extra power, therefore one does not run the engine at full all the time and maybe the engine will last longer in addition to getting out of the airport faster than to bug stupid NIMBY monkeys? DUH!
The meaning of life is curiosity; we were put on this planet to explore opportunities.
