Min Runway Take Off Lengths For A330,A340,777,787

Sat Sep 03, 2005 7:01 am

Im trying to find the following info. What is the minimum take off distance required for the following aircraft, fully loaded, in normal conditions (average temp, wind and height above sea level)?

A332
A333
A343
A345 inc HGW version
A346
A350?
777 - all versions
787?

I cant find any of this on Airbus websit and little on Boeings site.

The A343 about 6 miles of road that is flat and clear is the minimum that they need. They do actually take quite a good distance to get off the ground.

6 miles????????

Since 1 mile = 5,280 feet and the table provided by Planesailing shows the maximum distance at about 12,000 feet for the DC-8, Concorde, and B777-300, then the maximum is a little over 2 miles. The A343 is even less.

After a quick look I found out that these data are completely wrong and, of course,pro-B biassed. They compare apples and oranges. They say the A321 needs a longer take-off-roll than the A319 (  Confused ) and when comparing fuel capacity and take-off field lenght they compare the lowest gross-weight 772 with the highestgross-weight 343. They also claim that the 346 has a longer take-off roll than the 773ER, 744 and even 343, which is completely wrong.

Could you please stop making such childish comments? Here you can see some A343 rocketing off the 1.46 mile runway at St. Maarten. These are normal passenger flights going to CDG. The 744 can´t make it nonstop to Europe from there (except maybe LIS  Smile ).

Here at DFW (airport elevation 608') on a warm summer afternoon (around 100 degrees F, 38C), with winds out of the south around 10 knots, the AA (RR engines) and BA (GE90 engines) B-777-200ER use just over 9000' departing on 17R (13400' long) and 18L (13401' long). The LH A-340-300 departs shortly after BA & AA B-777-200ERs. LH uses just under 12000' departing on the same runways.

Normally, since BA and LH are going to London and Frankfort, they depart on 17R. AA, going to Tokyo, departs on 18L.

We have not had the A-330-300 here in a long time (Sabina used to fly to DFW before they went out of business), but, it had better take-off performance than it's A-340-300 sister.

It always amazes me how Emirates can get the 773 off the runway at BHX. A colleague of mine who is an expert in this kind of thing says he craps his pants when flying to DXB from BHX even on a A332. But then I suppose the aircraft are nowhere near their MTOW for the relatively short flight.

If he is an expert in aircraft performance, he should not be to concerned about an A-330-200, or a B-777-300 getting off the ground at DXB or BHX for a, what, 3500nm-4000nm mission?

To fly that distance, neither airplane would be carrying full fuel, but could be at or near MGTOW due to cargo.

Do you have any evidence to back up these comments? Honestly I think you are reading the data wrong, as the A319 needs a longer run than the A321, and the A343 and A346 are equal in take off difference. The runway length is measured by the height of the point.

Remember also, the FAR data is dependant on:



That includes the take off roll and climb rate to 35ft.

Dude A342,

Get a sense of humour. You do not get a joke when you see it. Jiminy Christmas. I know when I worked at IAD the 343's used to take the entire length of the runway, scaring the crap out of the GUard at the back gate.

Oops, yes, incidentally I changed the A319 to A321 and the A321 to A319, just like you did:

No they are not, the A346 is a lot better(2400 meters vs. about 3000 for the 343), but yes, in most cases it appears to be the same as they use FLEX-Thrust in order to save fuel and spare the engines.

Usually I do, but these hairdryer-engines-jokes about the A342/343 are a bit worn out, don´t you think?

ISA +20ºC SL.

737-300 - 2109 m
737-400 - 2475 m
737-700 - 2042 m
737-800 - 2316 m
747-400 - 3600 m
767-300 - 2850 m
767-300ER - 3996 m
777-200 - 2440 m
777-200LR - 3050 m
777-300 - 3540 m
319-100 - 2080 m
320-200 - 2590 m
321-200 - 2286 m
330-200 - 2590 m
330-300 - 2680 m
340-200 - 3260 m
340-300 - 3380 m
340-500 - 3550 m
340-600 - 3550 m
380-800 - 3350 m

One cannot draw any conclusions from the numbers above, nor the amount of runway used at an airport.

Each airline will have different procedures for the amout of "assumed temperature" that is used to de-rate the thrust from the engines.

A fuel conscious airline will use a high de-rate, using more runway, and less fuel. Another airline might lease its engines and have a lower de-rate, another might try and use minimum ground distance to increase passenger comfort.

is the 767-300ER information correct? I always feel 763s take off rather quickly.

Dont know, dont fly one. Wouldnt surprise me, 300->300ER lot of extra fuel and mass. The numbers above I think are at MAX weights.
