xXBornOfFireXx Posted August 23, 2012 Posted August 23, 2012 Correct me if I'm wrong, but I thought when taking off, after you reach around 100kts, you are supposed to pull the nose up 10 degrees and roll along the runway with the rear gears until the plane naturally takes off. That's what I've witnessed my AI wingman do anyway, but I know they can be a little dodgy. Well whenever I try to do that I fail completely. I've tried various amounts of pressure on the joystick to no success. The plane just seems to always lift straight off the runway from all three of its wheels at around 180kts, depending on weight. I turn NWS off after 50kts, have flaps to 10 degrees (also tried 20), but it still doesn't work. I'm thinking it could be my fairly old Logitech Attack 3 Joystick but I could also just be doing something stupid. Can anyone give me a hand? Cheers.
Pyroflash Posted August 23, 2012 Posted August 23, 2012 (edited) Post a track? When my aircraft hits 100 KIAS, I pull back very steadily until my nose lifts off, then shortly after at around 120 KIAS the aircraft lift off the ground. Depending on the load though, your nose may not lift off until you reach around 110 KIAS, however it should not be "lifting off of all three gears at the same time". The P-51D however, is a completely different story :D I've attached an example TO for you to look at (It's not very good, please ignore the shoddy landing :D).TOL.trk Edited August 23, 2012 by Pyroflash If you aim for the sky, you will never hit the ground.
xXBornOfFireXx Posted August 23, 2012 Author Posted August 23, 2012 Well when I said all the gears leave the runway at the same time, I may have been over exaggerating. But take a look at this track, you can see the wingman rolling along gracefully on two wheels while I'm bumping up and down all over the place.Failed Take-off.trk
Eddie Posted August 23, 2012 Posted August 23, 2012 100 KIAS is rather slow for a rotation speed, the rotation speed for a clean A-10C with full internal fuel and no gun ammo with 7 degree flaps set is 122 KIAS. To get a rotate speed of 100 KIAS, you'd actually have to empty out all the fuel as well. ;) With a typical combat load you're looking at a rotate speed of between 135 and 145 KIAS.

But take a look at this track, you can see the wingman rolling along gracefully on two wheels while I'm bumping up and down all over the place. It would appear that your track is broken, it shows your aircraft from the external (F2) view and you drift off the runway halfway along your take off run and end up taking off from the grass. If you make a new track hopefully we'll be able to see what you're doing wrong.
xXBornOfFireXx Posted August 23, 2012 Author Posted August 23, 2012 So don't touch the stick until I get 135kts (with combat load)? I have tried to pull back the stick at different speeds but it always seems unresponsive.
Eddie Posted August 23, 2012 Posted August 23, 2012 The specific speed varies depending on a/c weight, but 140 would be a good rule of thumb. When you hit the rotation speed, pull back on the stick SLOWLY and SMOOTHLY, hold the nose at around 10 degrees pitch and let the aircraft fly itself off the runway. The actual take off speed is around 10 knots above the rotate speed. Trying to rotate early and/or force the aircraft in to the air will only make your take off roll longer.
xXBornOfFireXx Posted August 23, 2012 Author Posted August 23, 2012 Here's round 2. Hopefully this one works. My AI buddy seems to roll along forever on two wheels, is that what it should look like? It's 3am here so I'm going to head off to bed (this thing has been keeping me up =P) but I'll be back on tomorrow. Thanks for your help so far.Failed_Takeoff_2.trk
Eddie Posted August 23, 2012 Posted August 23, 2012 (edited) Ignore what the AI do, they are not using the same flight model as you. That track is better, it still shows you changing to external view before take off, now if you are switching from the cockpit, don't. The external views are nice for taking pretty screen shots, but not much use for flying. The only real "error" I can see from that track is that you're not bringing the nose up to 10 degrees, make sure you do, just pulling back on the stick a bit won't do it. You need to bring the nose up and then hold it there. Edited August 23, 2012 by Eddie 1
xXBornOfFireXx Posted August 23, 2012 Author Posted August 23, 2012 (One last post before bed.) I thought as much for the AI, although I just had to be sure. I think the reason the replays were screwing up was because before I saved the track, I just watched it and switched to external, then saved it. I'm not that much of a newbie as to use external view =P. Anyway, I suppose all that there is to it is to practice. Thanks again for your help, guys, appreciate it.
