757 series or A320 series

[accinelli]

Which one is better? In response to the AA thread I wondered what the pilots of this great board opinion was on a direct comparison between both aircraft.

Not only as far as jumpseat comfort,passenger comfort but also,but more importantly which is a better plane to fly from a pilots perspective.

I vote for the 757. It besides the 727 is my favorite plane.

The A320 has a lower overall cost of Operation. Anyone get the picture now.

One big factor is the wing sweep. The 757 is 25 degrees and the A320 is 35 degrees. The A320 will cruise faster, the 757 will cruise more economically. It also improves the climb perfromance with the less swept wing.

The thrust ratings on those engines varied between 22,000 lbs and 27,000 lbs of thrust per engine.

I'd say that engine thrust on the A320 engines does sound very under powered. As for wing sweepage I knew the 757 was at 25 degrees but I didn't know the A320 was swept at 35 degrees!

Thanks guys keep it all coming. Learning alot!

This is a great post but having flown both I tell people who ask fly the one that has the best trips and working conditions.

The bus has a higher sweep, resulting in a higher critical mach and it's got a lower MMO which is interesting.

One of the reasons to increase the sweep is to increase the critical mach, which then in turn increases normal opeating mach resulting in higher cruise speeds.

What's mmo on the boeing, .84 or so? And .82 on the bus? I'd imagine it's going to take a fair amount of fuel to push that straighter wing to higher mach numbers, not to mention the overall weight. So it's not hard to understand why the bus wins out on cost of operation especially if you've configured it for higher density seating.

Interesting discussion.

I fly the 320 for JB... I have never flown a 757 just admired them from afar

Super comfortable plane.. The sidestick while cool is more artificial in feel than your joystick you use for microsoft flight sim at home.

Which plane would i rather fly? The 757 any day of the week.. An american built plane built by americans in america. Aluminum has been proven for years unlike the composite material which the majority of the bus tail is made of.

Why are we comparing a A320 to a 757, shouldn't it be an A320 compared to a B737 and a B757 compared to an A321? Going Boeing or Go Home!!!

Q. How can you tell the difference between the B757 pilot and the A320 pilot at the bar?

A. The A320 pilot has nothing bewteen his legs.

I keed! I keed!

What is MMO?

Yes, 36,000 lbs to 43,000 lbs of thrust PER MOTOR. On the -200 there are two pratt variants and two rolls variants.

The two pratts are 36.6 and 40.1
The two Rolls are 40.2 and 43.5

Those thrust ratings are PER MOTOR. And, as you know, the 75 has two motors.

You should be up to speed now in checking my calculations.

Technically the 757 has 2 engines. It has a lot more motors than that.

Patriot328, where are you????
