  1. The effect in game is different to RL. In game, the lateral offset that benefits from the drag reduction is too large. Also, the rotation-onset when flying into the wake field is rather large, instead of a gradual increase with a defined core. It's close to impossible to stay at a determined position inside the wake-field. Especially for similar sized aircraft the effect is too pronounced. NASA flight testing of two Hornets shows a FF reduction of 13 to 20% depending on flight-condition (slower leads to greater reductions) - and this only when large throttle-movements to maintain longitudinal position aren't made: https://ntrs.nasa.gov/api/citations/20030075684/downloads/20030075684.pdf https://www.nasa.gov/centers/armstrong/multimedia/imagegallery/AFF/index.html The effect IRL takes place over pronounced longitudinal distances, but requires rather precise lateral and vertical position (as one would expect). In game, my observation has been rather the opposite: A very strong dependency on a defined longitudinal distance and a rather large influenced lateral field. My observation has also been throttle-reductions of about 30% and possibly more, when very close. Keep in mind that thrust and FF doesn't scale linearly in turbojets, so the actual FF-reduction was probably more. It would be cool if anybody could manage to refly the test-setup in game and show their observed data.
  2. Free energy isn't sensible physics. It's going to become interesting with buddy-pod tankers. Just plug four jets in line and tail end Charlie gets to ride in idle.
  3. Wakes aren't modelled deeply at all. They'll give you a nice downstream-effect, but up close, they're a good deal off. The leading airplane will actually suck you forward if you're in a sweet-spot position (you'll need less and less power to stay in place). You'll also be flying sideways if you're hugging somebody's wingtip. This shows that the mesh is quite coarse, which makes sense as you don't want to run DCS as a CFD calculation.
  4. Looks more like Agean Batic tbh, though Love the first pic.
  5. That's not quite true. Turbulence is always a result of wind shear. Either vertically or horizontally. If there's no shear, there'll be no turbulence. Near the ground, shear is mostly a result of obstacles. Higher aloft, it's more dependant on frontal activities (that includes jetstreams), but gravity-waves may fravel downrange of ground-obstacles (eg. mountain waves) for up to a thousand miles, so it's a mixed bag. Hence if you travel at high wind-speeds, but no shearing layers, you'll be fine and won't have any turbulence at all. For thermals, you'll need a good representaion of atmspherical dynamics (such as convective potential vs capping layers, etc) and ground-air interaction. So far, our "beautiful clouds" (TM) are mostly stratus or cirrus type. The real fun, however, only starts with convection and multilayer CB clouds and associated atmospheric dynamics. At the end, you'll have to compromise between fidelity and game-code limitations. It would be cool if DCS could depict actual weather conditions, though.
  6. I'd also fall for a Cheburashka. Because it's cool.
  7. Sorry folks, but the only fun part the C-2 offers is landing on a carrier. A Transall would add dirt strips (well, we'd need a potent map for that), tanking (both on- and off-loading gas) and the possibility of a SIGINT variant. C-160 > C-2. I'd also like to see an An-24/26 series transport, so the reds get to play, too. All the proposed modern stuff isn't interesting at all. The C-130J will sufficiently tick that box.
  8. Hey Aerges, thanks for the new SAAF Spectre skin! Seems like there's a lighing issue on the tail, though. The tail appears overly dark:
  9. Early morning departure for a recce mission. RTB later that morning.
  10. "All the small things..." - Seen on LK. Daybreak above the Levant. Traffic at Gaziantep. On a Hi-Lo-Hi training mission. Topping off before commencing the 230NM low level leg. Alternators were harmed during the production of this photograph... High Level back to Ramat David. Descending for the initial RWY 33. === Dusk over the Canaries. Larnaca standing in for Gando.
  11. Croatia ain't half bad either:
  12. Has anybody ever experienced shedding a wing while flying through the wakes? Something the likes happened to me yesterday. Can't post a track as the game decided to record BS.
  13. +1 Please attach the Supers a bit forward on the pylon
  14. What's your climbrate or rate of descent when activating Alt Hold?
  15. I'm wondering the same, jojo. The signals should be the same in trim and AP. Could be my mistake, though, as the manual asks for depressing the disconnect trigger and pressing the AP button that the same time. Not depressing the trigger (me) could be the issue here. I'll give it a try. Edit: Just tested it: Doesn't change mich when using the trigger during AP engagement.
  16. Inboard pylons without the tips: http://bdd.deltareflex.com/cns_affiche.php?image=8037 http://bdd.deltareflex.com/cns_affiche.php?image=8036 (same jet, same day, different angle) Tips installed (no missiles) and S530Fs inboard: http://bdd.deltareflex.com/cns_affiche.php?image=20329 More chadian assymetries: Magic on the RH tip is covered. There may or may not be a Super on the LH inboard pylon. No Magic on the LH tip (only obvious via the shadow). Three Cornouaille jets with Magics on the RH pylon only. In Lela Presse Mirage F1 Vol.2 pg. 101 you'll see three EC 12 birds (Cambrésis, Picardie and Cornouaille) with a Magic on the LH launchers only. Same page shows Zulu India (see above), also with a Magic on the RH pylon only. Edit: In Alexandre Paringaux' book on the F1 we'll see Zulu Mike from the post above with a single S530F on page 117. Page 116 shows a Vendée bird with a single S530F. Both have the Super on the left pylon.
  17. That's also my feeling, but I'm no SME. I'd say that if the alternators were that vulnerable to overheating in certain flight-regimes as they are right now, that'd be a highly objectionable characteristic which would not have been cleared for ops. Edit: To be clearer on the latter part: It's probably realistic to overheat/ trip them at times, but right now, tripping them is very much guaranteed. Maybe the probability is a little to high?
  18. Taking fuel from the Trall could be well below 200kts, though. Mix in hot, humid air (roughly ISA +20°C), this combination would fry our alternators in a couple of seconds in game.
  19. @fausete is there a way to make the wing-pylons (Tips, Inboard pylons) be on the aircraft as standard, but deletable like on the other modules? https://www.airliners.net/photo/France-Air-Force/Dassault-Mirage-F1C/809005/L https://www.airliners.net/photo/France-Air-Force/Dassault-Mirage-F1C/2635284/L That way one could put asymmetric missiles on the tip-launchers or inboard pylons, which is now not possible (it won't put the other empty pylon onto the jet). Expanding this to all pylons (including outboard stations and fuselage station) would of course also be a workable solution. With the deletable option, I guess we can make the purists and those people driving for more flexible loadouts happy at the same time. French F1C-200s have been flying with asymmetric Magics or asymmetric S530Fs - or no Supers but with the pylons on (see top) - especially in Chad to keep the flight time on the limited supply of Supers low. Finding pics on the net for the asymmetric Supers is hard. I had once seen a pic where you could tell by the shadow. You'll find them in books, though, e.g. F. LERT "Mirage F1" pg. 45,46 and 52.
  20. The AP won't feed in rudder to keep the aircraft coordinated (ball isn't centered), so you'll do a slow turn towards the draggy side. Not sure if that's correct with anti slip on (AP may be using an entirely different control loop). The AP will just barely be able to keep wings level upon engagement with one Magic and S530 each missing on one side.
  21. Other lights aren't working as well. The Centerline External Tank empty light won't come on in the F1EE. Haven't tested the underwing-tanks or the CE yet. Pressing the TEST button (with a full centerline bag) gives me this: The auto-wind feature on the fuel-dial is on.
  22. A nice strawman you got there. You'll experience and observe the same amount of suffering that the F-4 pilot would have: None. Nape away!
  23. Apparently it does work and you'll need some time to do the ole "power cycle" trick. Takes a couple of minutes for the gyro spin itself down, though. I have never been patient enough to give it a try and I always just took another aircraft.
  24. I think DRF puts out some good advice, even though the F1 has gotten a good deal better in relation to the -21 with the last two patches. Things you have over the -21: A lot more internal fuel and a lot (almost a ton!) more dry thrust. What struck me, watching the video, is that you're making the common mistake of trying to pull the Sabre into your sight. Won't happen. Ever. You'll need to watch your AOA (try to keep it in the green, unless you can to kill the other guy within two-three seconds) and try to never go below 400IAS without a darn good reason. She'll rate quite well at 500-550 (or M.85). Keep the g low and try to let lag pursuit (barrel- and lag-displacement rolls) work for you, until you're in a position where you can kill him. The F1 is a hard aircraft to be good in.
