Short C-5 Take Off

Wed Jan 16, 2008 4:25 am

Allthough threre sounds like a lot of power, I really am impressed with the amount of surface area that just lifts it up fast....

Whoa that was crazy. That seemed like a ridiculously short run for takeoff!

I could be wrong, but it seemed to me its MLG lifted off just short of 5,000 feet from the start of the t/o run. Impressive, yes. But if it were empty, and if this were an airshow chances are it was, I would think it could do better than that.

I think its not bad.... i've been impressed by the C-17 take-off at my "home" airport of RAL (Riverside Muni)

Having ridden in the back of many fully loaded C5's...I can tell you that thing was empty of both cargo and probably just a basic load of fuel.

Stuff 76 pax, 3 H-3's, and all the support equipment necessary for a 2 week overseas deployment, and it makes for a *very* long take off run. Especially on those nice hot and humid days at Andrews AFB. Nothing like sitting in the back going, any minute now....any....minute....now....ANY TIME YOU WANNA FLY AIRPLANE! Honestly that's how I felt one flight. I couldn't be sure, but I think we used 10,000 foot of the 11,700 available that day!

Empty and with 90% empty fuel tanks it should do a lot better than 5,000 feet. Otherwise it would never do it on 10,000 feet when put to work.

That was my whole point (assuming, of course, the video showed a nearly empty C-5 taking off).

I haven't bothered to confirm, but I think at MTOW, the big beast actually uses closer to 11,000 feet to get its hulk airborne.

The C-5 video is not from an airshow.

That is from President Bushs July 2005 G8 summit, and is one of two C-5s that carried his motorcade to Prestwick.

Here is a much more impressive departure. This was at an airshow in 2003 at SWF (Stewart Airport, Newburg, NY.)
This flight was empty and lightly fueled, and was off the ground in much less than 5000'. More impressive is the right turn right after departure. Although I did not film this, I was at this airshow and almost at the same location. It was one of the most dramatic departures I have ever seen.

That isn't exactly a heavy load then, the bloody think is supposed to carry to M-1's.

You can get it off the ground on short fields with a load by using 62.5% flaps but there better not be any obstacles! At 62.5% she climbs like a pig! If you need to get off the ground quick you set 62.5 % then as you climb out go to 40%. Very rarely used! The only time I did it is when we were on a Spec Ops mission.

At MTOW the C-17 has an unimpressive power to weight ratio of 0.277. That is almost identical to (but slightly inferior to) an Airbus 340-600 with 0.278. Anyway it will probably at MTOW beat the A346 by a small margin due to its more lift than speed optimized wing airfoil section and state of the art high lift devices.

When empty it is an entirely different story since the C-17 can be loaded to way over twice its empty weight.

It depends very much upon temperature and runway elevation. At sea level and ISA temp it will hardly ever need that much concrete, but as temp and elevation rises, then everything is possible until wheel speed limit.

For very heavy and long flights from not too long runways I would assume that it would take off at way less than MTOW with reduced fuel load, and then visit a tanker pretty soon. That capability makes it a very capable aircraft.

Does anyone have pictures of the upper-deck area of the C5? I've searched all the photos and there's no pictures of the upper deck.

Like Prebennorholm said, it depends upon atmospheric conditions. Temperature and pressure altitude has a lot to do with engine performance. In very hot areas and higher pressure altitude we would need long runways (10,000 ft +). However, if it was very cold and/or at SL we could get off the ground on 8000 ft. runways at 769,000 lbs. all day long.

I know what you mean.. I have been up there once when I was little and I can't find a single photo to confirm what I remember.. It was kind of fascinating... bunks, several rows of seats, no windows.
Things were better when it was two guys in a dorm room.

I've seen one right here in the a.net database. I couldn't tell you the search criteria to use though.  Smile
