Hi PSS,why does the current B757-200 flips side to side when in 4x time ac? i cannot fly this way when it flips some isch minutes after I start time accelleration._______________________Regards, Torben Hadlerhttp://www.step-by-media.com die neue Community! Auch f

Torben,When you say current do you mean using the latest version from MY FILES?Is the aircraft in trim? What ZFW and CoG?

[t_a_h 0]

Yes, the latest release, it is in trim and the numbers are: ZFW: 183,999lbsCoG=0 or 100%I loaded the a/c with ACLoader and it flys and lands just perfect as long as I do not go more than 2x time acc. I already reduced framerates of the panel in setup, I am getting 6 to 12 fps while at cruze at 390 with live AS weather ans sliders around 85%_______________________Regards, Torben Hadlerhttp://www.step-by-media.com die neue Community!

>ZFW: 183,999lbs>CoG=0 or 100%CoG of either would be outside limits. Try somewhere in the mid/high 20s

Torben,I appreciate that you are a beta tester for ACLoader so will naturally want to use their product with our aircraft.From our perspective we can't really support both products. One thing I see immediately is that you have a empty_weight_cg_position of zero whilst by default ours is +3Please replace with the following values and try accelerated flight.[WEIGHT_AND_BALANCE]max_gross_weight = 256000.000empty_weight = 136940.000reference_datum_position = 0.000, 0.000, 0.000empty_weight_CG_position = 3.000, 0.000, 0.000max_number_of_stations =50station_load.0 = "320, 62.0, 0.0, 3.0, Pilot & Co-Pilot" station_load.1 = "600, 0.0, 0.0, 3.0, Technical Crew" station_load.2 = "5000, 45.0, 0.0, 3.0, First Class" station_load.3 = "13300, 28.0, 0.0, 3.0, Coach Class Fwd" station_load.4 = "13300, -28.0, 0.0, 3.0, Coach Class Aft"station_load.5 = "3000, 35.0, 0.0, -5.0, Cargo Fwd"station_load.6 = "4000, 15.0, 0.0, -5.0, Cargo Fwd Mid"station_load.7 = "4000, -15.0, 0.0, -5.0, Cargo Centre"station_load.8 = "3000, -28.0, 0.0, -5.0, Cargo Aft" ;Moments of Inertiaempty_weight_pitch_MOI = 5000000empty_weight_roll_MOI = 3600000empty_weight_yaw_MOI = 3000000empty_weight_coupled_MOI = 0.000CG_forward_limit= 0.000CG_aft_limit= 1.000

Hi,well, I found out that my cockpit weight is too much in the front. I reduced it to +62 and tried with that. Now I get a CoG of about + 2 to +3 feetAnd I reduced my scenery and effect sliders down to 78%, that reduced the problem of this bird to flip right and left at x4Well, I thought I would have a good computer to fly with around 80 to 85% all sliders maxed... I guess I have to spend the 100

Torben,For your info, my system is only based on an old 3200XP and, with the default .cfg, I have had the 757 regularly at 4x and 8x without any AP problems. John Rooum

Hi John,please would you show me your default fs9 cfg? may be I can tune some settings so it will run better..._______________________Regards, Torben Hadlerhttp://www.step-by-media.com die neue Community! Auch f

Torben,Sorry - I meant the default 757 aircraft.cfg ie as I installed with no changes to the aircraft loading.I will run a couple of tests to see if I can reproduce the AP problem and post back later.John

[FOD 23]

Torben,Just flown UK - Malta. TOC to s/c at 4X, then the step climb, final cruise and descent to 3000 ft at 8X. The AP was steady thoughout.My system is AMD 3200XP, 1.5Gb RAM, NVidia 6800 with the latest drivers. I have all sliders at around 3/4 with Traffic 2005 running at 65% and default weather. My aircraft.cfg loading is as per that posted by Norman.This problem was reported with the first release 777 - disconnecting the AP and then re-engaging often resolved it. If you do a search, there were two possible causes suggested - real world weather updating en-route and an early version of FSUIPC - but I cannot see how either could affect your system? What NVidia drivers do you have {a shot in the dark}?John R
