767-3 min TO runway length

[Guest pwapilot]

Hi-What is the minimum runway length for a 767-300 to takeoff?Thanks - pwapilot

http://www.pic767flyingclub.com/tern.htmHere you go. Note the takeoff speed in the rotation. Twas hairy to say the least, but no where to go but into the sea.

As I understand it, you are quite safe on any runway that is 7000' long. That is the standard for real-world ops in general. I don;t think I'd want to use shorter runways with passengers :)Tim

Dec. 31st, 2003 - B767-300 CYUL-CYYZ: 35 PAX, no cargo, contaminated runway (no derate). Our ground roll was less than 3000 feet (runway markers, about 2500ft used), initial climb out angle was 20 degrees plus, FD calling for almost 30 degrees to maintain V2+15.How long a runway is required? How long is a piece of string?I am not sure if there is an official "minimum" runway length, if I am light, 5000 feet seems to be a nice minimum.Rob.

Depends on your weight and conditions!110000kg, 10C, Sea Level, Nil Wind, Nil Slope = 3200ft.150000kg, 20C, Sea Level, Nil Wind, Nil Slope = 5900ft185000kg, 30C, Sea Level, Nil Wind, Nil Slope = 10300ft.As you can see, a huge range of distances required! These are the legally required field lenghts, not the actual distance the aircraft will be on the ground.Those distances are the longer of-a) Acceleration to V1, Engine Failure, Takeoff and Climb to 35ft.:( Acceleration to V1, Engine Failure, Aborted Takeoff.c) Normal Takeoff to 35ft plus 15%.In reality C is never limiting, so it will be one of either a or b that will limit the takeoff weight. Also at many airports there are obstacles after takeoff that can limit your takeoff weight on a given runway.

HPSOVI assume you use the assumed TOW to find out what the minimum amount of rwy is you can use?I.e. Say for example if one of your thrust reversers was inop, the rwy was contaminated with 5mm of slush, QNH 980 and a 5kt tailwind then there is going to be a big difference between the assumed tow and the actual tow? Thus increasing the amount of rwy needed?

[Guest HPSOV]

In reality the runway is of a fixed lenght... so instead of finding out the minimum runway required for a given weight, you're trying to find out the maximum weight you can takeoff with on a given runway.As an example, lets take a runway 7000ft (2130m) long, with no limiting obstacles, and look at two scenarios.15C, Sea Level, 10kts Headwind = 165000kg35C, 1000ft, 10kts Tailwind = 138000kg+5mm of Slush on runway = 124000kgSo you can see that on a given runway the weight at which you can takeoff varies greatly.You mention reverser inop... distances for an aborted takeoff dont take into account the use of reverse thrust, so there is no penalty for dispatch with one reverser inop (for takeoff). You are not however allowed to dispatch on a contaminated runway (such as the 5mm of slush) unless both reversers are operative.

...and I had no problems taking off from this aircraft carrier with a 120 kt headwind....:-)http://members.ozemail.com.au/~b744er/767/CarrierTakeoff.jpgCheers.Ian.

Chris, I guess these are Flap 5 figures.To get off 34R at Narita (2180m) the other night with a five knot tailwind we needed Flap 15 and full charge at around 160,000kg.
