CG issue since B 57.1.4
Posted: Thu Dec 08, 2022 2:43 pm
I flew the WorldFlight as member of Team JeeHell A320 with version B57.1.2 without any problems. As I did not make any updates during World Flight, I missed version B57.1.3 After updating to B 57.1.4 the following (fatal) problem occurs and is still present with B57.2.0:
I plan my flights including load as usual with PFPX, send the plan to TOPCAT and apply load and fuel to the A320 from TOPCAT via WideFS. And as usual I insert the values for Flaps/Trim, FlexTemp and V-Speeds in the MCDU as calculated by TOPCAT.
The issue begins with T.O. config test: I now get the (red) Message F/CTL PITCH TRIM/MCDU/CG/DISAGREE, I never had before. Inflight I realized PROG page does not show the OPT and REC MAX FL indication.That might have been caused, as I realized, by the missing ZFW on FUEL PRED page. In the past I never had to write something there manually when having done the fuel data uplink after loading. I now there inserted the ZFW TOPCAT showed for the flight. Now the OPT and REC MAX FL indication is shown on the PROG page, but FUEL PRED page shows a calculated ZFWCG of 25.0 while TOPCAT calculates a ZFW MAC of 31.8%. An issue?
The fatal thing comes at the end when landing: Vapp calculated on PERF page is 138 kts - not unusual compared with the past. But on final, as you can see from the attached picture, this speed is deep in the red area. But the plane does not go to protection mode, but keeps this too low speed until ending in stall and impact with >1250 ft/min in the lights before the threshold.
Note: Flying with Prepar3Dv4.5 on a Windows 10 system.
Anyone else with this issue since B57.1.4 (or 3)? Perhaps only those using TOPCAT for loading?
