FFX 737-800 Trim Issues

[Guest]

I have reviewed all the info presented here and have read all the posts and emails regarding the trim issues that some people are having and have gone back to rechecking data and made appropriate changes to the air and aircraft config file. All these corrections will be included in the 738 with winglets release soon. So for now, I'll just post the specific changes here. The air and config files for the 2 versions (with winglets and without) will be identical.Sorry, I don't want to release a dozen files with changes and updates. The air file you are using now will be fine, the new one will have some minor changes in it. As for the aircraft config file, copy and paste the data below in their respective areas. All the corrections were based on current actual 737NG data. I apologize for taking so long to address these issues, but time is at a premium. Please note again that these parameters will be the same for the 800 with winglets and the changes in the geometry section reflect winglets even tho what your flying currently does not have winglets. Don't worry about it.And just for your information, I took off with the new settings with 90% fuel load in each tank, Vref's were within the mark, had a steady climb rate (adjusted accordingly during climb), leveled off at FL320 and PFD showed a nose up of 3* degrees as it should be at a set speed of Mach 0.781. So if I see screenshots/complaints of radical trim and/or behaviour anymore, then I can only assume your doing something very wrong.Copy and paste the following info into their correct locations on your 738's aircraft config; (replace the "{" with the correct square brakets){General}atc_type=BOEING AIRCRAFTatc_model=B738performance=Power: 2x CFM56-7B24 @ 24200 lbs/thrustnMTOW: 174,200 lbsnMLW: 144,009 lbs (70% fuel)nZFW: 126,200 lbsnV1/VR/V2: 135/145/165 kts (MTOW)nVref: 135-140 kts (MLW)nNormal Cruise: M.78-M.80nRange: 3383nm (MAX PAYLOAD RANGE: 2926nmnLength: 129 ft 6 in (33.6 m)nHeight: 41 ft 2 in (12.5 m)nWingspan: 112 ft 7 in (34.4 m)(117ft 2in with winglets)/Vmo-Mmo: 340IAS (0.82MACH). 737-800 FDE by Mike Baumann FFX-Flight FX Group/Special thanks to Chris Trott for his help with fuel and other misc data{TurbineEngineData}Bypass_Ratio= 5.3000fuel_flow_gain= 0.0020inlet_area= 20.3320rated_N2_rpm= 29920.0000static_thrust= 24200.0000afterburner_available=0reverser_available= 1{airplane_geometry}wing_area= 1341.000wing_span= 112.700wing_root_chord= 11.910wing_dihedral= 6.200wing_incidence= 1.000wing_twist= -0.500oswald_efficiency_factor= 0.882wing_winglets_flag= 1wing_sweep= 25.000wing_pos_apex_lon= 11.600wing_pos_apex_vert= 0.000htail_area= 353.100htail_span= 153.900htail_pos_lon= -52.150htail_pos_vert= 7.000htail_incidence= 0.697htail_sweep= 30.000vtail_area= 284.200vtail_span= 27.200vtail_sweep= 35.000vtail_pos_lon= -44.600vtail_pos_vert= 10.300elevator_area= 70.500aileron_area= 26.900rudder_area= 56.200elevator_up_limit= 22.500elevator_down_limit= 19.500aileron_up_limit= 20.000aileron_down_limit= 20.000rudder_limit= 26.000elevator_trim_limit= 20.000spoiler_limit= 60.000spoilerons_available= 1aileron_to_spoileron_gain=3.000min_ailerons_for_spoilerons=6.000min_flaps_for_spoilerons=0.000{contact_points}point.0= 1, 51.00, 0.00, -8.70, 1574.80, 0, 2.251, 78.0, 0.308, 2.5, 0.639, 5.10, 5.30,0, 200, 280 //nose gearpoint.1= 1, -1.75, -9.50, -8.90, 1574.80, 1, 3.333, 0.0, 0.308, 2.5, 0.639, 5.30, 5.70,2, 200, 280 //left mainpoint.2= 1, -1.75, 9.50, -8.90, 1574.80, 2, 3.333, 0.0, 0.308, 2.5, 0.639, 5.20, 5.60,3, 200, 280 //right mainpoint.3= 2, -13.00, -58.85, 4.65, 787.80, 0. 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 5, 0, 0 //left wingpoint.4= 2, -13.00, 58.85, 4.65, 787.80, 0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 6, 0, 0 //right wingpoint.5= 2, -69.15, 0.00, 9.50, 787.80, 0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 9, 0, 0 //tail(set for hstab strike)point.6= 2, 69.55, 0.00, 1.00, 787.80, 0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 4, 0, 0 //nosepoint.7= 2, -45.15, 0.00, -1.50, 787.80, 0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0, 0, 0 //aft fuse scrape pointstatic_pitch=-0.90static_cg_height=8.60{flaps.1} //Leading Edge slatstype=2span-outboard=0.800extending-time=6.00system_type=1damaging-speed=280blowout-speed=320lift_scalar=1.000drag_scalar=0.800pitch_scalar=0.500flaps-position.0=0.000flaps-position.1=5.000flaps-position.2=8.000flaps-position.3=10.000{LIGHTS}//Types: 1=beacon, 2=strobe, 3=navigation, 4=cockpit, 5=landing light.0 =1, 17.20, 0.00, 10.30, B738_BCNU , //upper beaconlight.1 =1, 0.00, 0.00, -4.30, B738_BCNL , //lower beaconlight.2 =3, -12.00, -58.00, 4.65, B738_NAVR , //left navlight.3 =3, -17.95, -58.80, 4.21, fx_navwhi , //left idlight.4 =2, -13.00, -58.80, 4.65, B738_STROBE , //left wing strobelight.5 =3, -12.00, 58.00, 4.65, B738_NAVG , //right navlight.6 =3, -17.95, 58.80, 4.21, fx_navwhi , //right idlight.7 =2, -13.00, 58.80, 4.65, B738_STROBE , //right wing strobelight.8 =3, -64.50, 0.00, 7.00, fx_navwhi , //aft idlight.9 =2, -64.50, 0.00, 7.00, B738_STROBE , //aft strobelight.10=4, 61.00, 0.00, 5.50, B738_vclight , //cockpit splashlight.11=5, 29.40, -6.65, 2.50, fx_navwhih , //left inspection lightlight.12=5, 29.40, 6.65, 2.50, fx_navwhih , //right inspection light//IF FOR SOME REASON YOU CANNOT SEE THE BELOW LIGHTS ON YOUR FS, SIMPLY REMOVE THEM FROM THE CONFIG, SOME HAVE PROBLEMS VIEWING THESE FXlight.13=5, 26.00, -6.00, 5.00, B738wing , //-----|light.14=5, 26.00, 6.00, 5.00, B738wing , //-----|light.15=5, 12.40, -19.10, 16.40, B738wing , //-----|light.16=5, 12.40, 19.10, 16.40, B738wing , //inspection light splashes on wings and engines,normally lit druing t/o+landingslight.17=6, 70.00, 0.00,-10.00, MJ772TL , //nose gear light splash, remember to turn off taxi light before takeoff rolllight.18=5, 30.00, 0.00, -9.50, B738wing , //landing light splash under fuselage for 2 center fuselage mounted landing lightsI added 1 more light fx to the light section to give it the appropriate splash for the under fuselage landing lights.
