Vatikus Posted December 16, 2017 Share Posted December 16, 2017 With 1.5.8 I have noticed that if I have around 7aoa level and I start successive aileron rolls, the aoa will keep rising as you tumble more and more... One would expect that FBW will try to keep yaw component down Link to comment Share on other sites More sharing options...
GGTharos Posted December 16, 2017 Share Posted December 16, 2017 What one would expect is not what an FBW will do. F-18's experience the same thing in RL, there are videos of F-18's departing due to excessive yaw induced by roll.

Vatikus Posted December 16, 2017 Author Share Posted December 16, 2017 M2k is not f18. But what is more, have you actually tried replicating what I am pointing out? Link to comment Share on other sites More sharing options...
myHelljumper Posted December 16, 2017 Share Posted December 16, 2017 M2k is not f18. But what is more, have you actually tried replicating what I am pointing out? A track or a video would help a lot to see what you are experiencing. :) Helljumper - M2000C Guru Helljumper's Youtube https://www.youtube.com/channel/UCK3rTjezLUxPbWHvJJ3W2fA Link to comment Share on other sites More sharing options...
GGTharos Posted December 16, 2017 Share Posted December 16, 2017 Of course it's not. Do you know what an M2K is supposed to do? Other FBWs don't do it, why should this one? But yes, a track would be helpful or even a tacview in case the track doesn't play back right. M2k is not f18. But what is more, have you actually tried replicating what I am pointing out?

Vatikus Posted December 16, 2017 Author Share Posted December 16, 2017 I will record it tomorrow... The thing is that you are under control. No asymmetric load. There is no other pilot input except aileron, speed above 250kts and below 400, 7-8aoa... center stick at this condition, aileron in, AB power... and aoa will rise with each 360.. I have managed do get it near 50aoa, center stick, and aoa drops, and you are OK again. Link to comment Share on other sites More sharing options...
GGTharos Posted December 16, 2017 Share Posted December 16, 2017 I believe you. What you're encountering is not unusual - I mean it might not necessarily be correct but it doesn't sound strange.

jojo Posted December 16, 2017 Share Posted December 16, 2017 IRL they are not allowed to perform more than 2 successive rolls. Maybe you're "problem" is replicating a real one. Mirage fanatic !

Vatikus Posted December 17, 2017 Author Share Posted December 17, 2017 I have made a track... I did sequences of 2 speeds... the one where FBW introduces yaw by switching from ailerons to pitch forward, and at speed (400->) where this does not happen. I suggest that you should not just watch the track, but try it yourself as well. For me this shows some problem in control law in our implementation, is this true to life or not, I have nothing to back it up...

jojo Posted December 17, 2017 Share Posted December 17, 2017 Tested on Open Beta. Indeed, at 450kt no problem to pass 2 rolls. At 250kt I end up with yaw opposite to the roll. Mirage fanatic !
