Tiger-II Posted January 30, 2020 Posted January 30, 2020 (edited) Hi, I thought it was my hardware, so I set huge null zones to try and eliminate it. It made no difference. It's hard to describe, but I'll try... Regardless of whether symmetric stores are loaded or the aircraft is clean, the aircraft exhibits a tiny bit of yaw to the left and left roll tendency. It's as if there is some kind of gyroscopic precession being modeled as the result of torque from the engine? Engine torque yaws the aircraft, then roll-yaw coupling rolls the aircraft. It's strange.

The JF-17 is not better than the F-16; it's different. It's how you fly that counts. "An average aircraft with a skilled pilot, will out-perform the superior aircraft with an average pilot."
shaHeen-1 Posted January 30, 2020 Posted January 30, 2020 Never really noticed this. Would be surprised if FCS doesn't account for this.
Tiger-II Posted January 30, 2020 Author Posted January 30, 2020 It's verrry subtle. I seem to be very sensitive to things that aren't parallel, so when the aircraft starts to roll I notice it quickly. Try this: load up a clean jet, takeoff, climb to 8000 ft and 300 kts, level the aircraft, reduce power to hold speed, and just watch the roll pointer on the HUD. The thing that drew my attention to it at first was the roll issue but also the fact I kept having problems maintaining heading. I then realized what was going on. You'll need to fly for maybe 5 minutes to really see it. Make sure there is no wind or turbulence in the mission.

AeriaGloria Posted January 30, 2020 Posted January 30, 2020 Jet engines despite their vanes still produce torque and gyroscopic precession. I even remember it being listed on the MiG-29 PFM change log. I bet the 3 axis Fly-By-Optics on JF-17B and Block III handle this better Black Shark Den Squadron Member: We are open to new recruits, click here to check us out or apply to join! https://blacksharkden.com
