ScottyBS Posted May 29, 2016 Posted May 29, 2016 Hi, Been reported a while ago - any progress on this? Tanker gains ~70 kts when ready for pre contact. Ed
Frederf Posted May 29, 2016 Posted May 29, 2016 It's just how the DCS tanker logic is coded. They have a set speed for each type of airplane. Before and after the contact phase the tanker flies "however fast the mission maker said." The result is that the tanker will sharply change speed when you're ready pre contact and immediately after you stop contact from the correct contact speed to something else. That could be slower or faster. I hope ED changes this to extend the airplane-specific speed to more of the time near the tanker, say smoothly when closing form 5nm to 1nm and then keep this speed until the receiver is 1nm away or 1 minute after.
Azrayen Posted May 30, 2016 Posted May 30, 2016 They have a set speed for each type of airplane. Where?

After some testing, the tanker for most modules keeps the speed set in the editor.
nomdeplume Posted May 30, 2016 Posted May 30, 2016 I thought this was the case as well. After some testing, the tanker for most modules keeps the speed set in the editor. Most? What other modules does it speed up for?

KC-135 does not with both F-15 and A-10C. How so? Edited May 30, 2016 by azm

KC-135 does speed jumps too. (with M2000). Watch my airspeed.. (and it had already started gaining speed from the moment I had pre-contact) [ame] [/ame] Edited May 30, 2016 by CrashO
Gliptal Posted May 30, 2016 Posted May 30, 2016 The official campaing has no problems with S-3Bs set at 303 knots indicated.
azm Posted May 31, 2016 Posted May 31, 2016 (edited) KC-135 does speed jumps too. (with M2000) I thought that Mirage can`t take fuel directly from the boom )) Anyway, we have 4 planes with AAR capability and only Mirage causes tanker to speed up. So why RAZBAM says it`s not a RAZBAM problem? Gliptal, I must`ve missed something, do we have the official campaign for M2000? Edited May 31, 2016 by azm

So why RAZBAM says it`s not a RAZBAM problem? Gliptal, I must`ve missed something, do we have the official campaign for M2000? Not true. The speed up issue affects all modules that can AAR. It has been discussed before as you will see if you do a search.
Gliptal Posted May 31, 2016 Posted May 31, 2016 Gliptal, I must`ve missed something, do we have the official campaign for M2000?It's in beta testing. Not true. The speed up issue affects all modules that can AAR. It has been discussed before as you will see if you do a search.I have no problems with the Mirage on S-3Bs, or the Hog on KC-135s. The Ai has serious problems though.
codefox Posted May 31, 2016 Posted May 31, 2016 For me it only ever affected the Mirage (playing MP only) so far. I've refueled every plane that's capable to do so and the tanker only speeds up for the Mirage, regardless of which tanker it is. Tried with Il-78, S-3B and KC-135, result was always the same. Hearing similar results from other people. [sIGPIC][/sIGPIC]
Gliptal Posted May 31, 2016 Posted May 31, 2016 What is the tanker's speed? Indicated, not set in the editor. It may be accelerating if it's going too slow, possibly because of stall limits of the basket.
Shahdoh Posted May 31, 2016 Posted May 31, 2016 The tanker (no matter which one) accelerates to 400 kts eventually, no matter the ME set airspeed. Much faster then needed for the basket, and again, ONLY does this when the Mirage attempts to refuel. If there is an official mission for the Mirage where this does not happen, then need to figure out what they did differently to make it do so.
The Legman Posted May 31, 2016 Posted May 31, 2016 Same behavior. I set a huge square in way points each one fl200 and 300 kt. The tanker starts at 237kt and goes up to 270kt upon precontact. Maybe it's too slow for the drogue and it needs to speed up? I haven't found a way to keep his speed constant making air refueling really frustrating.

azm Posted May 31, 2016 Posted May 31, 2016 It's in beta testing. I see, looking forward to it, must be interesting. I have no problems with the Mirage on S-3Bs, or the Hog on KC-135s. The Ai has serious problems though. Could you kindly upload a simple Mirage AAR mission with S-3B tanker don`t speeding up?
Gliptal Posted May 31, 2016 Posted May 31, 2016 Could you kindly upload a simple Mirage AAR mission with S-3B tanker don`t speeding up?I'll see if I can replicate the mission.
The Legman Posted May 31, 2016 Posted May 31, 2016 When I introduce 454 kt on the editor (max speed for S3B) it begins at about 350 then slows down and keeps steady at 321kt without accelerating upon precontact. DCS Discord community - https://discord.gg/U8aqzVT
PiedDroit Posted June 1, 2016 Posted June 1, 2016 When I introduce 454 kt on the editor (max speed for S3B) it begins at about 350 then slows down and keeps steady at 321kt without accelerating upon precontact. What is the altitude? Speeds in editor are ground speeds and speed in the cockpit is indicated airspeed (decreases with air density). 454 kts ground speed should give 321 kts indicated air speed at around 24000 ft
nomdeplume Posted June 1, 2016 Posted June 1, 2016 Well, it sounds like the S-3B can work okay because it simply can't go any faster, so is unable to speed up. Don't know if that really can be considered 'working' though. :)

azm Posted June 6, 2016 Posted June 6, 2016 (edited) Another Mirage AAR thread`s dead :( Edited June 8, 2016 by azm
azm Posted June 8, 2016 Posted June 8, 2016 Dear RAZBAM, please tell us the truth whatever it is, shall we see the problem fixed?
Azrayen Posted June 8, 2016 Posted June 8, 2016 Hi azm, My personal opinion on the matter (I'm in no way speaking on behalf of anyone except myself): - is this annoying? yes (a little). - is this simple to reproduce? yes - is this simple to understand & fix? probably not - is this high priority? No! there are many other features needing attention: PPA (coming soon), INS (coming after), probably some other bugs too... I understand you asked a simple question. The issue is: answering it is probably not as simple as that ;) My 2 cents, Happy flights, Az'
