Tiger-II Posted April 20, 2020 Posted April 20, 2020 Hi, I noticed previously that the JF-17 has a "bump" in its FBW as it switches control laws/gains when putting the gear up. I thought this was isolated to the JF-17 (I assume you guys wrote your own FBW simulation) but I found the DCS F-16 does the same thing. Is this more of a core DCS problem or is it a bug specific to the JF-17 that just happens to look similar to the the F-16? (I'm taking advantage of the free month to try the F-16 in DCS for comparison to that other sim. :P ).

AeriaGloria Posted April 20, 2020 Posted April 20, 2020 It’s probably more of a core software problem. I would think it would be very hard to design a real life FBW that perfectly transitions gains and PIDs and all that so smoothly you don’t notice it Black Shark Den Squadron Member: We are open to new recruits, click here to check us out or apply to join! https://blacksharkden.com

It jolts, as if the elevator suddenly jumped from neutral to fully deflected kind of jolt. The closer to zero deflection of the flight controls (pitch INPUT), the less it happens. I trim first before putting the gear up - that helps. Motorola 68000 | 1 Mb | Debug port "When performing a forced landing, fly the aircraft as far into the crash as possible." - Bob Hoover.

LJQCN101 Posted April 20, 2020 Posted April 20, 2020 (edited) The JF-17 do have a fade-in module to switch gains smoothly but there was an implementation bug in it before. Now it's fixed and I think you can try that again. I happen to know the F-16 control law and it has a similar function too.
