Short Field Package

Recommended Posts

What does the short field package actually do to the performance of the aircraft? Tried it several times but i am not sure what i should be looking for? I am currently on a Round the World expedition with my NGX and will be needing some short field help in the coming legs. Any ideas? My RTW journey is about 95 legs in total.

Also, there is a very cool search function. I found at least 2 threats called "short field package"

Beside the fact that you two characters is playing sheriff, instead of helping the guy, I'm going to give him some information... SFPs characteristics are described in the documentation provided by PMDG together with the software, please refer to that for complete list of modifications. 737-800SFP is intended to be able to land/takeoff in extremely short runways. The shortest runway that a 737 can operate in the world is my home airport: SBRJ. Another good (a little longer than SBRJ) short runway is SBSP. You'll be pleased to land on both, but be patient if you make 3 or 4 missed approaches on SBRJ. It's hard to land there without practice.

Playing "sheriff" or just letting a first time poster know the rules here. Or better just just following rules; really the only rule here! *Cough* Witch doesn't even seam your following the FULL par of that rule. I guess rules are meant to be broken by most, nothing new there.

Gabriel I been meaning to ask you. Whats the Max Takeoff Weight for 737-800s at SBRJ?
That SHOULD NOT be above 68.000 kg for DRY operation (way below the MTOW), but you have to observe some restrictions: - No aircraft operates there with full tank. Most of time, it's around 20% to 40%.- ALWAYS must be selected 27K BUMP T/O Thrust.- MAXIMUM of 44ºC for Assumed T/O Temp- "Rolling Takeoff" is not allowed.- Flaps 15º or 25º is allowed but 15º has the best performance, especially after takeoff when you must climb immediately to the left to avoid the Sugar Loaf (1336 feet) ahead.- NO GO for tail winds above 5kt.- NO GO for RWYs 20R/02L. You must T/O and Land on RWYs 20L/02R. For T/O on WET conditions, it should be, if I can remember, 64 MT. But the real number must be within 2 MT +/-. For LANDING, you must not be above 58,2 MT for both DRY/WET and must set the AutoBrake MAX, and the temperature must not be above 40ºC. Just ask me if you have any other doubt! I'd be glad to help you.

He had to agree with the rules prior to acess this forum. It's not your responsability.

Look it is the only break these guys get from counting their paper clips .. .. Don't go ruining their fun, even if it is tedious in the extreme for everyone else. G

I don't think there was a definitive answer to this in the other threads, but does the SFP reduce V speeds? Doesn't seem to in the sim, but does it in real life? Or is it "just" increased breaking efficency, higher spoiler angles, etc. Martin Wilby

Edmundo, these are airport specific conditions for a particular company.

SFP does not affect V speeds, but it reduces take off and landing distance, thus allowing higher weights to be used.

SFP does not affect V speeds,
Whats this then...
Flight spoilers are capable of 60 degree deflection on touchdown by addition of increased stroke actuators. This compares to the current 33/38 degrees and reduces stopping distances by improving braking capability. Slats are sealed for take-off to flap position 15 (compared to the current 10) to allow the wing to generate more lift at lower rotation angles. Slats only travel to Full Ext when TE flaps are beyond 25 (compared to the current 5). Autoslat function available from flap 1 to 25. Flap load relief function active from flap 10 or greater. Two-position tailskid that extends an extra 127mm (5ins) for landing protection. This allows greater angles of attack to be safely flown thereby reducing Vref and hence landing distance. Main gear camber (splay) reduced by 1 degree to increase uniformity of braking across all MLG tyres. Reduction of engine idle-thrust delay time from 5s to 2s to shorten landing roll. FMC & FCC software revisions.

Okay so 68.000 kgs is 149,000 lbs or less for takeoffs, with max takeoff weight in the NGX being 174,000 lbs. Seems like it would be less than 149,000 lbs thats only 25,000 lbs less than MTOW?

Hello Edmundo! No, those are SBRJ Standard Operation Procedures specific to SFPs, which is not included on PMDG docs.

I'm not sure, Paul... but I think SFP has MTOW of 89.000 Kg or 196.000 Lb

Gabriel, Is there any more information or tips that you are aware of and can share about operating in short fields? By the way, thanks for the information that you have already shared here. Now can i have safe flights in and out of Santos Dumont, i was looking for those weight limits for a while.

Nice thread. Good information in it. Too bad it is not long for life since several people here think they are better than the rules of the forum, and inexplicably retailiate when they are asked to follow them.

Well maybe that is an ER version. The Max Tow Weight of the PMDG 737-NGX is 174,000 I not sure what I weighed total when I did the flight. However when I tried to take off with 20,000 lbs fuel, 12,000 lbs Cargo and 162 Pax (Max 2 Pax Configuration) I barely cleared the runway.with about 100 ft to spare.

I hope the lower VREF with the SFP will be included in the first service pack. If not, I would be interested in knowing by how much VREF is reduced with the SFP. Apparently the pitch increases to 3.5 degrees on approach, from 2.5 degrees, for the 800 with flap 30, so it's only a one degree difference, so I'm guessing by about 5-10 knots or so. Martin Wilby

Gabriel, I just tested 737-800NGX at SBRJ. Landed through Teleferico cable and high hill to RW02R and stopped at 3000 Ft. MAX brake settings with 40 Flaps. It was a good challenge. Specially flying between hills and cable.LOL.gif Sanal

I would seriously like to take a large plastic spoon and dip same into a coarse pancake batter until coated with copious amounts of the aforementioned flour, egg, and milk based emulsion, then finally, with little or no fanfare, fling the raw mixture at you. I would futhermore like to repeat the above steps several times in quick succession.
Made me chuckle.. Ill join you!..lol

I just want to thank everyone who has contributed to answering my question seriously, without the need to play sheriff or be a little sarcastic in ur answer. So for the sarcastic amongst u i am sorry i didnt follow the rules and sign my name on my original post, how careless of me not to let the whole world know my name, i am sure the earth will fall off its axis because of this mistake. Be good and happy simming Ben Morton, or is it Donald Duck? hmmmm DD
