777-300ER

How much rwy for MTOW 777-300ER?

Recommended Posts

I'm about to purchase the PMDG and want to practice some V1 cuts at max structural TO weight (775,000), so I'm wondering what the minimum takeoff rwy for a a 777-300ER under the following??

1) Standard conditions (Sea Level, 1013mb/29.92hg, 15C/59F)

2) Paved, level and dry rwy

3) Calm wind

4) Flaps 15

5) TO thrust with engine bleeds open and both packs off.

Also.......would accelerate-stop be the most restricting in terms of runway length required or would it be accelerate-go....if you lost one right at V1?

 

Anyone know what the min required takeoff runway would be for the same conditions above, but on a wet rwy?

Thanks very much

This what you need?

For 777-300ER/GE90-115BL

From the FCOM: weight x 1000lbs.

Based on engine bleed for packs on, engine anti-ice on or off, and wing anti-ice off or auto.

With engine bleed for packs off, increase field limit weight by 1100lb

Corrected field length for your specs (DRY, 14C) @ 769.5lbs.: 10,600 ft.; @ 782.4lbs.): 11,000 ft.

Corrected field length for your specs (WET, 14C) @ 763.2lbs.: 10,600 ft.; @ 777.7lbs.: 11,000 ft.

(WET, 14C) @ 791.7lbs.: 11,400 ft.; @ 805.5lbs.: 11,800 ft.

(WET, 14C) @ 818.8lbs.: 12,200 ft.; @ 831.7lbs.: 12.600 ft.

Thanks very much. Can you send me a link where I can get that info because I'd love to play around it with various weights, runways and conditions.

Also, I'm a bit confused though..... How did you get numbers above 775K lbs?  Isn't that max structural weight?

The numbers I presented are from the FCOM. I have no first-hand knowledge whether anything there is correct, only that it came from the documentation provided when you buy the product. I did find it very interesting that there are aircraft weights and rwy lengths for wet rwy that exceed dry - I woulda never thought.

I won't provide the actual doc as I don't want to get on the wrong side of copyright, but this link to a different resource might help. Looks like you have to "join" to download.
