Коллеги! учитывая значительное число вопросов, связанных с "непонятным поведением" 64го вертолета мы решили помочь нашим пользователям в преодолении этого "барьера")) С этой целью возможна организация онлайн семинара в дискорде. Кто желает - напишите в личку Pilotmi8 в формате: логин [дискорда]#ID (в дискорде) После этого оценим количество участников и примем окончательное решение по проведению. Время примерно -через 3-5 дней. Можете также указать желаемое время начала встречи, чтобы учесть пожелания большинства коллег. Покажу и отвечу на вопросы. Темы для обсуждения: аэродинамика вертолета, двигатели, САУ двигателей, САУ вертолета, модель повреждений (касаемо аэродинамики и двигателей). 64_take_Off.pdf

Edit/TLDR: I believe the SCAS might somehow be working against the pilot inputs. But only when the controls are trimmed off-center. Could this be a bug? Details below. Apologies for the long post but the problem I am trying to describe is kinda subtle. I am not sure if this is a bug or intended behaviour, but I find it puzzling and would be grateful if someone could explain to me what happens and why. Track attached. I am using center trim mode for both stick and pedals. I do 3 short takeoffs and hover "attempts". Before every takeoff I center the trim and hold force-trim up until the green markers are centered in the control indicator. 1st takeoff I leave the trimmed position at the center and do nothing fancy. I just take off and hover. Watch the SCAS indicator for the rudder. It is basically centered around the white indicator which shows my current rudder position. Of course I am not the greatest pilot so the SCAS goes a bit to the left and right sometimes to stabilize the hover. But in general it stays centered around the white marker. This behaviour is pretty consistent with my expectations. (land, center controls, desaturate SCAS) 2nd takeoff Before takeoff I push the rudder to the right a bit, press and release force trim up. The trimmed rudder position is now a bit to the right side of the center (the red rudder trim indicator has moved to the right). I take off and try to hover again. The green SCAS indicator for the rudder now appears much less centered on my actual rudder position (white indicator). It is visibly shifted to the right (towards the side where the rudder is trimmed). It appears to be working against the position I am trying to hold with the pedals. I keep the hover up for a bit and then land again. The green SCAS indicator is now stuck at the far right side of its authority box (SCAS saturated?). Is that really correct/intended behaviour? At least it is not at all what I would expect. I would expect the SCAS to behave exactly like during first takeoff (mostly centered around the white marker, stabilizing my moves. Not with an obvious bias towards the right side). (land, center controls, desaturate SCAS) 3rd takeoff (bonus question) Before takeoff I pull the cyclic back about 50%, press and release force trim up. Recenter the stick, then pull it back again all the way (as far as it can go) and hold it there for a few seconds. Then I let go of the stick again and recenter trim. The SCAS indicator for the cyclic is now stuck at the bottom of its authority box. I move the stick around a bit just to check if the SCAS indicator can in fact still move (it does). Now I take off. The SCAS keeps applying full back pressure (as far as it is allowed). I have quite some trouble keeping the Apache stable. Again my question: is that intended&correct behaviour? If yes, could someone please explain to me why this happens and what I am doing wrong? This behaviour makes the helicopter really hard to control for me. And it seems that this only happens when I use the force trim. If I just hold the cyclic/rudder in place without ever using force trim-up, then I can fly for extended periods of time without any odd behaviour. Thanks! AH64-SAS.trk
