Caldera Posted March 28, 2022 Posted March 28, 2022 Hey All, I am probably using the wrong term, my apologies. To me FPM = Flight Path Marker or TVV = Total Velocity Vector is how I know it to be called. Anyways, I am getting better at flight in the AH-64D so I have more time to notice stuff. My biggest improvement was turning off Pitch and Cyclic force trim. I do use force trim for the Rudder (thrust) and I am noticing something a bit weird. The FPM is always hanging out to the right, For right turns it will sort of align to the boresight, but for left turns and most other times it is way off to the right. Please take a look a the picture. This was a fairly difficult screen shot to get and hence the reason it seems a bit twisted due to my body contorting to press the PRTSC key. What would I be doing wrong? Thanks in advance, Caldera
agamemnon_b5 Posted March 28, 2022 Posted March 28, 2022 You're not doing anything wrong. In aerodynamic trim, the Apache crabs a bit. 1 [sIGPIC][/sIGPIC]
Hiob Posted March 28, 2022 Posted March 28, 2022 You're doing nothing wrong. That is an inherit characteristic of helicopter flight. You're either in Nose to tail trim, which will you're ball go off center to the left. Or in aerodynamic trim, which will make you "crab" along a ground track and your FPM off center to the right. Basically the anti-torque heckrotor pushes you to the right, and to counter that, you need to off center your nose to the left. 1 "Muß ich denn jedes Mal, wenn ich sauge oder saugblase den Schlauchstecker in die Schlauchnut schieben?"
Solution S. Low Posted March 28, 2022 Solution Posted March 28, 2022 Brads an Apache pilot. In this thread he explains that crabbing should be present but it’s excessive currently. He details it out and gives a fun diagram on forces acting upon the aircraft https://forum.dcs.world/topic/296438-advice-on-aerodynamic-trim/?do=findComment&comment=4924727 1
