Maybe a -400 is much lighter than a -800..

Rick,Yes I did, thank you. I have been hunting around for your email to make a reply. Could you please PM me with your email address?Your letter was incredibly appreciated, thank you!

Hi JanePM sent.

at the risk of disagreeing, the SFP gets significant improvement in landing distance, both from the engine idle improvements and the deflection of the spoilers to 60 degrees.

Risk away. You are correct.I guess from my standpoint, operationally, I see the flaps difference. But, of course you are right. I've never seen landing distance nearly as limiting as the takeoff distance. My experience with 737-800SFP was into airports in Hawaii for ETOPS, so it was always near MTOW.

1310935134[/url]' post='2019116']I suspect I'm going to show my ignorance here but why does the NG(X) need short performance packages when BA currently fly the common or garden 734 into and out of Gilbraltar every week?

MTOW for a -400 is 68 metric tons, or 68000 kilograms.For a -800, MTOW is just shy of 80 metric tons, or 80000 kilograms. In this case, just shy means 1 kilogram :(

Note that GOL doesn't do SBRJ at anywhere close to MTOW - they run SBRJ to Sao Paulo Congonghas, very short flight, not a lot of fuel.

For takeoff on a "normal" length runway, like at YSSY for example, would real world operators use flaps 5 or 10? If taking off on a short runway with the short runway package, would it be flaps 10 or 15? I'm confused!

True. The distance is so short that the aircraft doesn't have enough distance to reach it's optimum cruise altitude before the ToD. The last time I flew this route, our cruise altitude was of 33000ft, and we didn't stay that high for very long. I'd say less than ten minutes.

Flaps 5 is sort of the standard for "normal" takeoffs with the NG. On short runways it's 15 or (in the case of something like SBRJ) 25. GOL has performance charts for Flaps 25 out of there. Flaps 1 actually gets used fairly frequently with a light 600 or 700 too.

How do you know that? Did you found it in the internet, someone from Boeing is feeding you with those data or are you working with someone from GOL? I'd be really excited to know that you have an actual GOL employee helping you there!

Hi Guys,I've really enjoyed this particular thread, I always enjoyed the precision you needed to apply when doing short field operations. A few years back, a small airline called OZjet (I think) went bust here in Western Australia and one of the TAFE colleges acquired one of their B732's as a training platform for their LAME students. That meant that it had to fly a short hop from Perth International (YPPH) to Jandakot (YPJT) which is 20nm south and is our primary GA airfield in W.A. Jandakot's main runway is 1392m (4566ft total length but with displaced thresholds at either end) and apparently it was quite a spectacular landing, athough I didn't get to see it.Just one question about short field take-off in jets, why wouldn't the pilot stay on the brakes until the engines had reached full power before beginning to roll? In the video, you can hear the engine spooling up as he is completing the turn around to line up. What would be standard procedures?Cheers,Greg Johnstone

Thank you Thomas :(

When checking YT videos they indeed seem to be at flaps 5 most of the time. Even back in FS98 the 737 checklist said flaps 5 (alright, performance calc wasn't really an issue back then...). Interestingly enough though, and I don't know if that's a 'US' thing, but over here across the pond I have yet to see one single flap 5 departure. They actually use 1 whenever they can, obviously. Not sure why that is, maybe most of our runways are just not as short as SBRJ... Just for your reading pleasure. :(

Main gear camber (splay) reduced by 1 degree to increase uniformity of braking across all MLG tyres.

Sorry, anyone care to elaborate? I have no clue as to what this means. :(

I think (After looking at some photos on Google) that it is the degrees that the wheel is tilted.
