Most major int'l airports have at least 2 runways used regularly for arrivals and departures. In most cases, one is shorter than the other. What is the average length of the longer runways at major airports around the world (11,000', 13,000') ??

Well at MSP, the main runways are 10,000 and 8,000 feet. The cross runway used for NWA 747-200'S mostly is 11,000 feet. So, I'd estimate between 9,000 and 11,000 feet maybe, depends on the airport though.

All the major airports which typically recieve heavies (747s, etc) have close to 4000m (12,000 foot) runways, at least those which had the room to build them. I'm not sure, but I think the longest runways in Europe are in Munich, which are not far from 5000 meters.
So I'd say the average length for the longest runways will be around 4200-4300 meters.

CLE, though not that busy of an international airport, receiving no pax. widebody service, our paralell runways are 9000 feet and 7000 feet. Within 5 years, they will be 11250 and 9000 feet. Although you may think 9000 feet is not a lot, a 777, DC-10, and 747 can all take-off and land on this runway before.

I'm just wondering whether or not existing facilities (runways in particular) will accomodate the new generation of widebodies/longreach arcraft, i.e. the A380, perhaps some new version of a Concorde, the proposed Sonic Cruiser...
It seems that many airports have runways in the 10,000 - 13,000 range. I presume the avg would be 11,000 so if that's the case will this be enough concrete?

Could someone with greater technical knowledge than me please answer Sonic99’s question. I am unsure of FAA regulation regarding the length of runway needed for an aborted takeoff beyond that actually used by the aircraft during its takeoff run.
Example: Would an A380 need a 12, 13 or 14,000 foot runway to meet regulations for a takeoff run, even if it only actually uses 11,000 feet of that?

MUC does indeed have some of the longest runways in Europe (not couting millitary) but they are 'only' 4000m x 60m (which is 13,123ft by 197ft) sounds a lot, but the elevation is 1497 ft. It will be perfectly enough for any version of the A380 to liftoff.
The 747 at 0ft and (I think +15°C, no winds) needs 10,000 ft of runway (3048m).
DEN is building a 16,000 which is the longest CIVIL runway afaik.
I think the longest ACTIVE runway is one of Edwards AFB's 30 runways, it is somewhere in the high 20k ft or even 30k ft long.
The required takeoff length depends on a HUGE number of factors which include: Mass at takeoff, elevation of runway, current outside air temperature, SLOPE of the runway (quite important if high), etc
