I flew on a 737-400 this morning and I noticed how quickly the aircraft accelerated and it got me thinking.What passenger aircraft has the best power(thrust) to weight ratio?In other words if we had to line them up on a huge drag strip what aircraft would accelerate the fastest with similar loads over a given distance?I have a feeling the 747 SP would be right up there but I'm not sure...any ideas?

I'm sure that nothing would beat an empty 777LR. Not even a 757.


I'd rather die peacefully in my sleep, like my grandfather, not terrified and screaming, like his passengers

The daily UA 744's to MEL from SYD are said to have VERY short take-off runs.
I'm not sure about pax planes but some G-V's have big engines. 29 360lbs of thrust on a 30m (98 feet) plane seems like alot to me.

In another thread (757 Take Off Roll Less Than Smaller Planes) B2707SST published a graph with the following data:

Concorde: 0.375
752: 0.341
712: 0.339
A32X, 737NG, A306, 762: 0.31 - 0.335
A342, A343: 0.22
A388: 0.25

All other 0.265-0.31.

In the group of A32X, A318 should be on top.

I think that the correct answer to this is:

I believe that Korean Air 773s have the highest power to weight ratios, because they are equipped with the PW4098.

Korean Air was the only airline to order the PW4098 due to the mishap that PW had with the engine and as a result, they are the only airline to operate the engine. I think that they've even got better power to weight ratios than the 772LR or the 77W.

With someone mentioning the G-V, I'm sure others like the LJ45 and Citation X would totally beat the aforementioned airliners as well.

I read somewhere that the CRJ-700 competes well in this category; comparable to a 757.


Never let the facts get in the way of a good story.

No airliners, but Eurofighter and F-22 raptor are certainly among the best airplanes in terms of thrust to weight ratio altogether.

On www.flightlevel350.com there is a cool video taken on a Varig MD11 flying from CDG to AMS. If I counted correctly, it took around 18seconds to take off. Try to watch it, it is really cool. I can confirm that empty Cargo MD11s taking off from CGN are real rockets...

I agree with TheSonntag: 11 minutes from standstill to 36,000' with an empty cargo MD11 leaving Khartoum.  bigthumbsup 
I've also seen them climbing with 4200'/min with a full paxload......rockets indeed.

The plane in the video, PP-VQI, is now OH-LGG, due to emerge from the AY maintenance hangar in late Dec.
