GRoss Posted July 3, 2010 Posted July 3, 2010 Hi everybody! After around a week of practice in dcs: black shark, I felt that I am ready (ready enough :megalol:) to start the first campaign, first mission - which is pretty much flying, following a mi-24. So I've been following mi-24's lead for around 30 minutes, with a few overspeed warnings to be honest, but everything was still good. The problem that I did have was when I was flying at ~250 kph, and then made a pretty sharp left turn and tried to stabilise, and with no warning whatsoever my rotor blades clashed :joystick: and I have watched that track a few times and it doesn't seem right that that has happened.... ..now I've had my share of rotor blade clashes in the last week and can tell when that's my fault (all the time), but this particular crash seemed weird. Anyway - thought I'd share with you all, and if anyone wants to have a look - the link to the track file is below - quite big though (~3MB) since the flight went on for a while oh and also - I'm trying to get used to the trim function, which is good mostly, but somehow I can never get the trim right and keep the chopper in balance, so by the end of this flight my right hand was REALLY tired from trying to keep the helicopter steady (never before happened to me, except for that hour-long f-18 carrier landing training session I've had once ) http://www.megaupload.com/?d=NXTVY6OP
Nate--IRL-- Posted July 3, 2010 Posted July 3, 2010 (edited) I've not watched your track but in general when flying over 250kph (Indicated Air Speed) be very careful with Left Cyclic and Right Rudder inputs. Edit:- When trimming it is a good idea to Press and hold the trimmer, get the Helo the way you want it, then release the trimmer Edit2:- Just watched it (~25mins in if anybody else wants to see) Yep, too fast and lots of left cyclic. Hitting the trimmer at that point also releases its authority, which is not what you want to happen at the edge of the flight envelope. Also there is no need to set the throttles to emergency power, automatic will be fine unless flying on one engine. Use the CTRL-ENTER indicator to see what your controls are trimmed to Nate Edited July 3, 2010 by Nate--IRL-- Ka-50 AutoPilot/stabilisation system description and operation by IvanK- Essential Reading
GRoss Posted July 4, 2010 Author Posted July 4, 2010 Thanks for pointing out my mistakes 8D, but I though that when flying at high speeds, turning left will not cause rotor blade collision - its the right turns that should be avoided, no? Had no idea about the engine power as well - I figured, the more the merrier haha. Also for the trimmer - I know in theory how it works, but a few questions: 1) Even when trimmed, the helicopter will still need adjustements to keep on course - thats fine right? 2) How do can you tell the position of the cyclic (thats the joystick right?) when trimmed, in relation to its original position, without using the CTRL-ENTER method - in other words, how would pilots do that? Thanks for the reply 8D
Booger Posted July 4, 2010 Posted July 4, 2010 (edited) 1) Even when trimmed, the helicopter will still need adjustements to keep on course - thats fine right? Yeah, albeit small ones if you've trimmed the aircraft well in that particular heading. I usually trim at least twice during heading changes. One to get "roughly close", then another to get right on course. Others may get it the very first time. 2) How do can you tell the position of the cyclic (thats the joystick right?) when trimmed, in relation to its original position, without using the CTRL-ENTER method - in other words, how would pilots do that? The trim in the actual KA-50 will keep the cyclic in the trimmed position...the cyclic won't recenter like how it does in the sim. I think it keeps it's position realistically in FFB HOTAS? I think I read that somewhere, but could be wrong. Edited July 4, 2010 by Booger

Had no idea about the engine power as well - I figured, the more the merrier haha. As I said before - the faster you go, it is Left Cyclic and Right Rudder you have to watch for, not actual turns. Each, or even worse, both of these will move the 2 rotor discs closer together on the right hand side. You'll also notice that at high speed you need a bit of left cyclic and right rudder just to fly straight. Also for the trimmer - I know in theory how it works, but a few questions: 1) Even when trimmed, the helicopter will still need adjustements to keep on course - thats fine right? It should be very possible to trim so the helo won't need adjustments. Be sure that the Autoplot is actually following the heading you have trimmed. I'd suggest switching switch 7 on pg 2-68 of the manual to the middle position. 2) How do can you tell the position of the cyclic (thats the joystick right?) when trimmed, in relation to its original position, without using the CTRL-ENTER method - in other words, how would pilots do that? Thanks for the reply 8D Real pilots know this from the actual position of the Stick, as do we if we use Force Feedback Sticks. CTRL-ENTER should be used at all time IMHO.
