wolle Posted March 29, 2017 Posted March 29, 2017 It seems to me that the joystick (I have a warthog) in the Huey does not allow you to cover the full range of cyclic deflections. What I mean is if I pull back on the joystick, then trim, and pull back again, I can get a larger backwards deflection of the cyclic in the chopper. Or another situation: I am trimmed for forward flight, and lose the engine and need to auto rotate, I can not pull the cyclic back enough to enter the flight regime for autorotation. What I have to do is pull the joystick back, then trim, then pull back some more. Is this how the real helicopter works? I would think not... is there a way to change the control settings such that the joystick gives you the full range of cyclic deflection without having to trim half-way?

Sandman1330 Posted March 29, 2017 Posted March 29, 2017 To answer your other question, no this is not how the aircraft works in real life. In fact, the whole concept of the "central position trimmer" is unrealistic. It is a way to compensate for the limitations of computer joysticks. In the real aircraft, the cyclic has no resistance at all, no centering force. If you let go of it, it will simply flop to the side. Force trim is a system of magnetic brakes that holds the cyclic in its current position. There is some give and the pilot can push against the resistance, but for large movements the force trim release button is pushed. This releases the brakes and allows the cyclic to be repositioned. Once in the new position, the button is released and the cyclic remains held in the new position. What this means in practice is that there is no centre, per se. On the ground is the only time you will see the cyclic centered. In hover, the position that holds the hover is typically back and left (depending on wind and centre of gravity). In forward flight, it will be significantly forward of centre. The force trim just holds the cyclic in this position. This is why it is vital to have 0 curves and 0 deadzone, because these assume the stick will return to centre. For the most realistic simulation that we can get on a PC, take the entering springs completely out of your stick, if able (X-55 is awesome for this). Then, forget about trim entirely - just fly. Position the cyclic as necessary for the regime of flight and just hold it there. It simulates flying with the force trim turned off (or flying an aircraft without force trim equipped). For the Huey, it's not that unrealistic - many of us RL pilots turn the trim off, especially in the hover - it allows for greater precision. A good force feedback joystick could theoretically simulate the force trim properly - I know my old Force3D Pro kind of did, but not very well.

Focha Posted March 29, 2017 Posted March 29, 2017 (edited) have to trim to get full cyclic deflection range, realistic? I can't speak for the Huey, but the explanation above is pretty accurate for other helicopters with hydraulic assisted controls. But for the AS350 B3, with trim system (most of them don't have it), you can feel a little resistance due to the hydraulic fluid and some rotor forces. On the AS365 with dual hydraulics you can't feel the forces, the force you feel is an artificial one to assist in not getting pilot induced oscillations when you press trim release. But most of the time you will fly with trim and adjust with beep trim (hat switch on the cyclic). Only if large and abrupt maneuvers are required you will press the trim release. Else you will feel the magnetic centering force where you trim the cyclic. Also I have been using a MSFF2 and it somehow simulates the force, but there was a 3rd application program somewhere that you could use and simulated 3 parameters (centering force, resistance, dampening) which was a lot more realistic than the forces in DCS. If anyone knows the software name just post it here. Regards Sent from Tapatalk.
