Denver (DEN) To Build 16,000FT Runway!

Fri Oct 06, 2000 11:56 am

Denver officials have approved a 6th runway to be built at Denver Int'l (DEN). Denver officials hope that the new runway will attract new international airlines to Denver. The runway will be 16,000 feet long and will be the longest civilian runway in the world! Construction will begin sometime in 2001 and will take 6 to 9 months to complete. The cost of this new runway is $150 million. Any more details? Does anyone know how wide it will be?

Kind regards to all.

Did they get the federal funding that they requested for the runway? Where did you find out about this? Thanks.

16000 ft? What for?

The Space Shuttle perhaps? Imagine that! DEN-LHR ont the Space Shuttle!

The real reason that they need this is for fully loaded 747-400's to takeoff out of there. I predict that United has plans for some new long haul routes out of there with the 747-400. This plane cannot take off out of there fully loaded because at that elevation the tires are not able to spin fast enough for the airplane to build up enough speed.

DIA77,
Yes they did get federal funding. Its official now. Construction is to begin next year and to be completed some time late next year or early 2002. Denver officials predict that this new runway will attract new Asian airlines. Japan Airlines is interested in adding Denver in the next few years!

Kind regards,

I agree that the reason this runway is being put in is to attract international long haul flights from Europe and the Pacific Rim. In order to do so, you must have a runway that is capable of handling a fully loaded 747-400 on your hotest days.

I was just rading allong and thinking to my self that a 16,000 ft runway is @#$%*&$ huge!! I know it is for elevation and all. now that means it is approx 3 miles long. The avg person walks 2-3 mph so figure 2 hrs to walk down and back on that runway, I cant imagine walking nonstop for 1 hr and that beign the length of a runway! thats crazy huge! cant wait til next time i fly to DEN.

Just curious does nayone know what kind of #'s you would be looking at for a 747-400 @ 5000 feet on a hot high and humid day?

"This plane cannot take off out of there fully loaded because at that elevation the tires are not able to spin fast enough for the airplane to build up enough speed.'

I don't think the elevation makes the tires spin slower.   Even if it did, the tires don't push the plane down the runway, the engines do. Or maybe I misunderstood what you were trying to say.

Two factors come into play in determining how much power a jet engine will produce: a)Temperature of the air and, b) Altitude of the air.

Warmer air is less dense air. Less dense air means the engines are getting less material to produce thrust.

Likewise, higher altitude air is also less dense. Again less material for the engines to produce power.

Yes, it is true, higher altitudes produce cooler air, but density is more sensitive to altitude than to temperature. The atmospheric temperature decreases only by 3 degrees F per 1000 feet. And even Denver gets red hot in the summer, its elevation notwithstanding.

Often a plane like a 747 will have to decrease its load to affect a safe take-off on a very hot day anywhere in the world. If it is also a higher altitude airport, even more so. Denver on a summer day would be a double-whammy for a laboring 747 full-loaded like a boat leaving for China.

The engines can produce enough power for flight of course, but with less dense air they need more time to build up to that. That means they need a longer runway.

Hmmmm...

A.K.A. Density Altitude: pressure altitude corrected for nonstandard temp. They say for every 1.8 degrees Fahrenheit, or 1 degree Celsius, density altitude increases by approximately 120 feet. It is basically the altitude the airplane "thinks" it is at.
