RE: Why Are 757's So Popular In Eagle/Vail?

Quoting a321luke (Reply 47):
If you're going by MTOW, then yes, the 752 beats the 77L weight/thrust:

B752: 255,000/43,000 = 5.93
B77L: 766,000/115,500 = 6.63

I rounded the numbers somewhat for thrust, so the numbers aren't perfect. I'm also not sure what engines the 757s that operate to EGE have in terms of thrust, so I used 43,000 lbf.

OEW on the other hand, the 77L beats the 752:

B752: 127,500/43,000 = 2.97
B77L: 320,000/115,000 = 2.77

Both are incredibly overpowered aircraft that go like a bat out of hell at full power when empty.

You are calculating with only one engine. And just to illustrate the ratios of some of the mentioned planes in this thread I have calculated some of ratios. These numbers are all based on what I have been able to find online.

ThrustWeightRatio

As with regards of OEW, it is try that 77L is better, but I have never heard of a plane taking of from any airport only based on OEW. No pax, cargo, fuel, crew? No. Especially from EGE.

OMG I'm so sorry guys! It was probably waaaay too late at the time for me to be posting haha. I apologize.

Do the aircraft that take off from EGE use full thrust? I'd think that a 752 wouldn't, but something like a 738 or A320 would.

I see that UA Express is currently running a DH8-400 to EGE.

Quoting ATCtower (Reply 45):
This is my airspace and while the 757 is certainly a big bird for the airport, I would hardly say it is a popular plane for the field. I could be wrong but even during peak ski season there are only 2 daily 757s that go into an airport which can run a 30 rate and sometimes higher...

2 daily? Are you talking about EGE? Look at last winter and winters past. There were so many more than 2 daily in the winter and even more on saturdays. AA alone on sat flies one to LGA, JFK, MIA, LAX, ORD, and 3-5 to DFW. I am sure that will go down with the 319s coming on board but EGE does see alot of 757 daily even weekdays. It was the most common plane in the winter at EGE. What is interesting is that Delta has loaded the 757-300 for EGE-ATL this winter on dates.

But of course, the 77L uses a lot more runway than the 752 to take off, so that's a huge reason why we see them at places like EGE.

But if you just loaded enough fuel to fly to EGE to JFK, I'm sure the 77L would have really good runway performance even with a full load of passengers and baggage.
