February 6, 200422 yr Hi!Today Sebastian and I completed our updates to the 757 flight model, and after some heavy duty testing we feel that the new version 2.0 is ready to fly !The improvements in the new version are as follows (from the readme.txt inside the package):- Enhanced pitch properties. Pitch is now more stable and calm, and not so sensitive. The normal trimming range for normal loading (ie. COG position) is around 4-5 units NOSE UP for takeoff. The new pitch properties can also be seen in a smoother rotation, which, by using correct amount of the stabilizer trim (4-5) will result in a smooth V2+15 profile.- Enhanced roll properties. The roll-rate was excessive during large aileron inputs. This behaviour is now corrected, and a lot more consistent.- Corrected oscillation during ILS approach. The glideslope oscillation is now entirely gone, and the aircraft will fly rock stable ILS during even the worst of conditions. The autoland is now also a lot smoother.- With the new pitch properties, crosswind landings are a lot of fun. You can actually land the aircraft on one of the main gears, and gently feel the other one coming down, with the nose gear following last. No abrupt "collapsing" onto the runway after touchdown anymore.The package is available AT ONCE!NOTE! all older v1.0 version users! The new v2.0 package is available in the EXACT same location, with the EXACT same package name. So, if you still have my email saved somewhere, you can use the same address to pick up the new FDE. IF, for some reason, you desire to also download the OLDER v1.0 FDE, it is available in the same URL except for the package name which has _100 added into the name (ie. B752_PW2037_100.zip)Those of you who don't have the older version request email saved, and all the new users, please email one of the following addresses to get a download URL for the FDE package:Sebastian Hyv PPL(A)
February 6, 200422 yr Let me head the bandwagon by saying, "Thanks you guys." You do an outstanding job and I believe we ALL are grateful!Roger Curtiss
February 8, 200422 yr Sebastian,Loaded the v2 FDE today and took my POSKY B752 w PIC767 panel for a spin. I deleted the v1 FDE and aircraft.cfg file in favor of the updates in the zip.I'm curious if anyone notices that this thing really jumps off the runway...literally rotates at around 90kts. Haven't changed a thing in the config for the regular flights I've done [fuel, flaps, etc etc etc etc]GeneDAL211
February 8, 200422 yr Hello Gene,I too have experienced this with no matter how much trim I apply, it always rotates between 90-120kts by itself.Maybe Teropa can elaborate on this?Regards,Alexander Martin.
February 8, 200422 yr Hi Guys,Please check what TRIM setting you have before takeoff. I just did a couple of takeoffs with 20,000lbs of fuel and when the TRIM was 6 units the plane starts to rotate at about 95-100kts. The trim should be between 4 and 5 units depending on takeoff weight. With a fuel load of 20,000lbs 4.25 units is a pretty good value.Can anyone else duplicate this behaviour with correct trim setting?Best Regards,Sebastian
February 8, 200422 yr Author Hi,Like Sebastian said, it's not possible that the FDE rotates by itself with a correct trim setting.Our FDE depicts approximately the situation where C.G. %MAC is 24. That leads to the situation where the STAB TRIM settings are roughly as follows. (taken from B757 AOM)GW Trim260 5240 4.75220 4.5200 4.25180 4160 3.75767PIC has the "feature" of drooping the stabilizer to 7 units when hydraulic pressure is removed from the system, ie. that is the value where the trim will be when you start the a/c from cold. You will NOT want to leave the trim at that point. The kind of problems described in this thread will arise immediately should you neglect setting correct amount of trim for takeoff.Tero PPL(A)
February 8, 200422 yr Author And let's iterate some more still!FOR FS2002 ONLYIt does say that in the readme as well!Tero PPL(A)
February 9, 200422 yr I just flew KBOS to KDCA and set the trim at 4.5 for 22,000lbs fuel and it rotated perfectly. Thanks for the work you're doing on this, it makes the POSKY 757 and PIC767 panel work beautifully.DAL211>Hi Guys,>>Please check what TRIM setting you have before takeoff.

February 9, 200422 yr Author Gene,Good to hear you got it working.With your TOW of ~ 198,000lbs the trim should, infact, be still a little less. Around 4.2 to be exact.Tero PPL(A)
February 9, 200422 yr Tero,I finally found some time to install the 75 airfile. From what I have seen so far, I am impressed - you have nailed v2+15.Btw - did you get my email with the Finnair FPs.
February 9, 200422 yr Author Hi Mark,I'm glad you like it!!No I haven't gotten that email. Did you use: [email protected] ?Interesting... ;)Tero PPL(A)
February 9, 200422 yr Hello there,Sorry to be a nuisance...I'm afraid that I seem to be experiencing the same problem. I must be doing something drastically wrong as I too, get a very quick rotation. This despite a stab trim setting of approx 4.5 units and a GW of 220...Furthermore, after rocketing off the auto pilot cannot maintain the desired climb rate as the aircraft just keeps on going up until stalling. I can only get out of the stall by letting the speed bleed off as applying full nose down still gives me a positive rate of climb...makes for a very interesting emergency approach...my virtual passengers have been delighted:+ and virtual shares in "barf bags" have soared !!Any ideas on what I'm doing wrong would be appreciated...Many thanks and a huge thanks for all the work & effort that you put in to this FDE.Cheers
