CaptainCernick Posted July 3, 2011 Posted July 3, 2011 I recently took up flying in the A10C again and I'm having a lot of fun training. Looking forward to some combat missions later. But I'm having some issues with the sim, and I'm not sure wether I or the software is to blame. The first has been with me since the beginning. I call it the 'sticky nosewheel issue'. Basically, rotation during take off is very difficult to control. In my take off run I speed up to 110 kts and start pulling back gently on the stick. The nosewheel does not seem to want to come off the ground though. Ultimately, the stick is full back and still no rotation (even though I should be well past Vr by now). At about 140 kts, the nosewheel suddenly "unsticks itself" from the runway and the aircraft leaps into the air violently. It's not a pretty sight and I'd like to do it right. Am I doing something wrong or is it something else? I already checked my joystick axes (using a Saitek X-52) and they register full deflection. The second issue wasn't there when last I played DCS A10 (Patch 0.6). The EAC switch just doesn't want to stay in the "on" position. I know it wont unless EGI is aligned, EGI navigation is selected and SAS switches are engaged. I triple check these things every time I do a rampstart, but still no EAC. I'll record a track and upload it here later. Thanks in advance for the help!
genbrien Posted July 3, 2011 Posted July 3, 2011 (edited) Are you trimmed for T-O? 110kts maybe slow for rotation.... try gently at 120-130 just for fun And for the EAC, if you roll 2-3ft, will it work (I cant enable EAC at the starting position, must always roll a bit to engage it. Works for me :)) Edited July 3, 2011 by genbrien Do you think that getting 9 women pregnant will get you a baby in 1 month?[sIGPIC][/sIGPIC] Mobo: Asus P8P67 deluxe Monitor: Lg 22'' 1920*1080 CPU: i7 2600k@ 4.8Ghz +Zalman CNPS9900 max Keyboard: Logitech G15 GPU:GTX 980 Strix Mouse: Sidewinder X8 PSU: Corsair TX750w Gaming Devices: Saytek X52, TrackIr5 RAM: Mushkin 2x4gb ddr3 9-9-9-24 @1600mhz Case: 690 SSD: Intel X25m 80gb
CaptainCernick Posted July 3, 2011 Author Posted July 3, 2011 Thanks for the swift reply! I have tried turning on EAC during taxi, but it still won't work. Makes me think I am forgetting something important during startup after all. I'll try again and triple-triple check my checklists. Maybe rotating later could be the answer, I'll give it a try and get back.
PlainSight Posted July 3, 2011 Posted July 3, 2011 (edited) Yeah, you must rotate at 130-140, especially with full load. 110 is minimal speed. Check this out: source Edited July 3, 2011 by PlainSight [SIGPIC][/SIGPIC]
Cibit Posted July 3, 2011 Posted July 3, 2011 As soon as I reach +50 I ease gently back to reduce stress on the nosewheel and after 100 ease the stick again. Depending on loadout I will pull back for controlled take off between 135 and 145 knots IAS. With regards eac I suggest posting a track of your start up procedure up till taxi. :) i5 8600k@5.2Ghz, Asus Prime A Z370, 32Gb DDR4 3000, GTX1080 SC, Oculus Rift CV1, Modded TM Warthog Modded X52 Collective, Jetseat, W10 Pro 64 [sIGPIC][/sIGPIC] Adding JTAC Guide //My Vid's//229th AHB
hassata Posted July 3, 2011 Posted July 3, 2011 I know you say EGI is aligned, but just to be sure, is it flashing before you attempt to engage. With T/O try not pulling back at all until 140-150. [sIGPIC][/sIGPIC]
shu77 Posted July 3, 2011 Posted July 3, 2011 Since 1.1.0.8 EGI also needs to be the selected NAV source to get EAC to engage. I find I cant move to EGI from the initial HARD without rolling forward 5 feet. Try the Roll, then test brakes, and Chage NAV source to EGI and arm the EAC at that point before continuing your taxi. That said can anyone tell me the purpose of needing to move the plane forward first?

CaptainCernick Posted July 3, 2011 Author Posted July 3, 2011 Thanks for the replies! Alright, so rotate later is the message. I'll keep it in mind. The track of a rampstart and take off are attached to this message. Keep in mind, take off weight in this track is pretty light. No external stores, no gun ammo, 60 percent fuel. NWS disengaged at 65, I attempt to start rotating at 120 kts. (please overlook the zigzagging on takeoff, I'm still having trouble controlling the rudder/nosewheel during take off. It's just so sensitive) As for the EAC switch, you'll see me trying to activate it twice: first after EGI has aligned, nav selected in CDU, EGI navigation enabled, SAS switches on and again when I've taxied some distance. It wouldn't work.Rampstart.trk
159th_Viper Posted July 3, 2011 Posted July 3, 2011 That said can anyone tell me the purpose of needing to move the plane forward first? Not necessary. If you are too lazy to hit the 'Nav' OSB on the CDU after alignment, then moving forward will automatically select Nav mode for you. Novice or Veteran looking for an alternative MP career?

159th_Viper Posted July 3, 2011 Posted July 3, 2011 wait until INS alignment complete before pressing NAV OSB Aye - you interrupted the alignment process about a quarter (?) of the way through. Alignment is only complete when the CDU flashes 'INS NAV READY' - Only then do you hit the Nav OSB.

Dodgeza Posted July 3, 2011 Posted July 3, 2011 Wait for Full Alignment 4.0.0.8 before pressing NAV OSB - then switch from HARS to EGI then turn on EAC. Make sure you have your flaps set to MVR or FULL for take off I find MVR good enough for lift. TO Trim important too... 130kts then rotate.

CaptainCernick Posted July 3, 2011 Author Posted July 3, 2011 This is my advice after reviewing your trk RTFM Fuel pumps on before APU I assumed this was only necessary for engine start. Noted. wait until INS alignment complete before pressing NAV OSB Ah... so this is where I went wrong the entire time. I thought when the "nav" option on the align page had it's little bullet next to it, alignment was complete and I could activate "nav" mode. Press Take off trim after SAS switches You'll see me doing this in the pre-take off checklist. I don't know why, but in other sims also, I always check trim while holding short. brush up on your start up and read a start up check list yours seemed a little rushed and disjointed but your on the right lines so keep at it:) I'm using the checklist that came with the manuals. I'm starting to feel too confident now and I'm starting to rush things and do stuff by memory (with the obvious result of forgetting stuff) On the take-off front, things are looking up. I'm rotating later and mytake-offs are smooth now. IIRC, the take off tutorial tells you to rotate at 110 kts, and that got stuck somewhere.

LostOblivion Posted July 3, 2011 Posted July 3, 2011 Anyone know what 4 and 0.8 means, or are they just meaningless internal alignment calibration variables? I've also seen a video of a real A-10 where it said 4.1 0.8. Nice plane on that gun... OS764 P930@4 MBUD3R M6GB G5870 SSDX25 CAntec1200 HTMHW

BlueRidgeDx Posted July 3, 2011 Posted July 3, 2011 (edited) Yes, the "4.0" referred to by others is the elapsed time that the EGI (INS) has been in Align mode. It counts higher than 4.0 in the real world, hence the 4.1 in the picture you saw. The "0.8" is the drift rate in nautical miles per hour of the INS portion of the EGI. Without GPS updating, a fully aligned INS can be expected to drift as much as .8nm/hr. The smaller the number displayed here, the better. With GPS updating, the drift rate is effetively nil; however, the CDU is only displaying how accurate the INS is, not how accurate the EGI (INS + GPS) is.

Ripcord Posted July 3, 2011 Posted July 3, 2011 If starting a mission on the runway, is it safe to assume your EGI is already aligned? [sIGPIC][/sIGPIC]

Conure Posted July 3, 2011 Posted July 3, 2011 Hi, Add a curve to your rudder via the axis control settings. Made a world of difference to my take off control. I would also set a bit of a curve across all axis for when you start air to air refueling. I suck at it, but I suck less now that I've added the curve.

Best check Pitot tube heat is on:thumbup: OK so here is my situation, starting my mission on the runway. We've decided that the EGI is already aligned in this situation. My problem here is that I my flight controls are completely out of whack once I do get up in the air. Gear retracted, flags retracted, etc. All of a sudden I just start wrestling with the stick to keep it from banking or rolling over, and it is a huge chore to even keep it in the air, and no chance of just flying straight and level. What in the hell can be causing this? :joystick: Now a couple of clues that lead me to believe something is wrong. First is when I start the mission the caution warning light is going off and beeping. Cannot for the life of me figure out what the hell that is. So the plane is trying to tell me I have a problem, I just am not bright enough to understand what that might be. I keep coming back to EAC armed, and that's why I am posting in this thread. I have a TM Warthog HOTAS and it is set up in the sim to sync up at the start of the mission. Should I be starting the mission with the EAC armed? I am going to test that again to see if this is my problem, but I don't think so. If nothing else, I guess it will be a chance save a track to post here and maybe get some help!!

ivanwfr Posted July 4, 2011 Posted July 4, 2011 2 guesses worth checking as it will be easier than packaging a track: 1 - "banking / rolling" looks alot like lift problem (unlikely as you're not noob it seems) 2 - "sim sync" AFAIK, only gives you a chance to match your HOTAS switches to what you see on your screen during sort of "ACTIVE PAUSE" you get into after your first hit on PAUSE key... Only the second hit will get you in control. my 1¢
