PSS a320 bouncing like a yo yo?

[Guest Ali]

Hello.Just purchased the PSS A320, and properly setup for a flight. On takeoff, rotation in particular, I had to pull back very fiercely on the joystick. Also having to always correct my pitch so I don't pitch too high or pitch too low. Up to acceleration altitude I was struggling to keep the aircraft in the air. I decided to engage the AP1, where things settled down, still wasn't behaving properly though.During the entire climb to 37,000ft I could barely manage 200kts, the autopilot was commanding a V/S of 4000ft for some unknown reason.I checked fuel figures and had 4 tonnes reserve for my flight, weight was around 54,000kgs ZFW, nothing unusual there.I put it down myself to trim, I've tried setting it to -2.0 DN but it still doesn't seem to cure this bounce effect after takeoff and all the way during the climb.Any ideas?Regards,Alexander Martin.-----------------------------------Previous FlightsBAL341A Friday 27th August: EGKK-LGZABAL341B Friday 3rd September: LGZA-EGKKhttp://members.virtualjet.co.uk/vJsigA.jpg

go to the folderaircraftPSSAB-Propanelpanel.cfgand open panel.cfg with notepadlook for this section(Window08) <<==should be square bracketsBackground_color=16,16,16size_mm=2,2position=7visible=1ident=59make sure the linesize_mm=2,2is correct, make changes as required, exit and saveJohnPSS SUPPORTsupport@phoenix-simulation.co.ukhttp://www.avsim.com/pss/phoenix.jpg

I've done that and it doesn't change anything.Why would changing a panel entry alter the way the aircraft would fly?Regards,Alexander Martin.-----------------------------------Previous FlightsBAL341A Friday 27th August: EGKK-LGZABAL341B Friday 3rd September: LGZA-EGKKhttp://members.virtualjet.co.uk/vJsigA.jpg

Startup flight is the default flight with the cessna 172.I have fixed the mouse flicker, that's not an issue.Start the airbus, cold and dark.I am not impressed.Regards,Alexander Martin.-----------------------------------Previous FlightsBAL341A Friday 27th August: EGKK-LGZABAL341B Friday 3rd September: LGZA-EGKKhttp://members.virtualjet.co.uk/vJsigA.jpg

In the pure PSS (compared to the iFDG/PSS merge)I find it best to go to selected mode above FL250 and set V/S to about +400 which gets you to the cruise level without losing airspeed. The reason is that if you remain in managed mode the pitch up is too steep so airspeed bleeds off, the nose then comes down and the airspeed picks up again and the nose pitches up again etc etc. Selected mode stops this. Watch the airspeed indicator tos ee where the best point is to go to selected mode as it will vary depending on winds, weight and so on, but for me it is usually arounf the FL250 mark.

Surely if it's called "A320 professional", you would expect to fly it as true to life as you can, within the limitations of Fs.Thanks Rob for the workaround, but this is no way to use a product that I have spent money on.Regards,Alexander Martin.-----------------------------------Previous FlightsBAL341A Friday 27th August: EGKK-LGZABAL341B Friday 3rd September: LGZA-EGKKhttp://members.virtualjet.co.uk/vJsigA.jpg

Hi Alexander,You're right of course about using a product in this manner on which you spent money... But I use PEDRO OLIVEIRA's flight dynamics which are made specifically for the A320 by PSS and for IFDG. Your problem I don't have - but I do have a rather poor climb performance of about 800-900 fpm after about 28,000 feet ASL when using FMC and letting the autopilot do the work. Autopilot keeps the airspeed constant at a climb rate of 298KIAS and reduces the nose up pitch as altitude increases. NO bobbing or irratic behaviour at take-off though and I can even run accelerated simulation rates as high as 8X without any crashes or irratic aircraft behaviour.John

I had the same issue above FL250 with the iFDG/PSS merged A319 a couple of nights ago. But it isn't a problem, it is just something to watch and I adjust my rate of climb accordingly. For me it's a bit like adjusting the way I drive to fit the road and weather conditions.Alexander, as your problem with the yo-yo effect starts straight after takeoff (and is a problem on the ground as well) I think something has got messed up with your air file or its relationship with the panel and aircraft config files. Perhaps it would be worth you getting hold of Pedro Oliveira's flight dynamics or using a merged iFDG/PSS to see what the difference is. By the way, it's odd that you say you have just purchased the PSS A320 as I know from our lengthy chats last year about various aspects of flying it that you had it then before leaving BAV to fly 757s with another VA. Perhaps you deleted the Airbus somewhere along the line. If so, welcome back to a great aircraft and keep plugging away with it because it is worth it.

I had the boxed edition with the video but the CD got so badly scratched.When I saw the PSS sale I was tempted but it's a temptation I wish I never succumbed to now.I have tried the Pedro merge with the IFDG model but it's not behaving as it should.I'm left in the dark, requested a refund but with no reply.Regards,Alexander Martin.-----------------------------------Previous FlightsBAL341A Friday 27th August: EGKK-LGZABAL341B Friday 3rd September: LGZA-EGKKhttp://members.virtualjet.co.uk/vJsigA.jpg

well if it doesn't work with the default setup or the merge by Pedro?perhaps it's not the product but your PCtry deleting the filesmodulesfsuipc.dllmodulesfsuipc.inire-install only fsuipc.dllre-calibrate your flight controlsalso deleting FS9.cfg or FS2002.cfg can solve alot of problemsif that doesn't work contact Support with your refund requestPSS SUPPORTsupport@phoenix-simulation.co.ukhttp://www.avsim.com/pss/phoenix.jpg
