  1. Nope. One last attempt: 1. Max instantanous rate/load factor, which is what this thread concerns, is all about the lift available vs the weight of the aircraft (up until FCS limit), i.e. you follow the lift limit curve. The DCS F-16 is incapable of reaching its max rate/load factor at the speeds where it should, in this case 9 G's @ M 0.67 @ SL: 2. Ps+/- curves (specific excess power) are there to show you what rates/load factors the aircraft can maintain, the number telling you wether the aircraft needs to lose alt to achieve it, or wether it can do so whilst maintaining or even gaining alt. Example: Ps=-600: Sustainable rate/load factor at -600 ft/sec alt Ps=0: Sustainable rate/load factor at 0 ft/sec alt Ps=+100: Sustainable rate/load factor at +100 ft/sec alt
  2. To stay OT I will say that the F/A-18C very much still outrates the F-16C in DCS when under the same load conditions, and not by a small amount either. Interestingly the F/A-18 keeps this rate advantage all the way up to its G limiter, even when you use the override (been able to sustain 9.6 G's in it), i.e. the DCS F/A-18's rate somehow doesn't really fall off as you'd expect it to. The only fighter than can currently beat a competently flown F/A-18C in a turn fight in DCS seems to be the F-14, and only if it forces the fight into one sustained around Mach 0.5-0.6.
  3. You apparently don't understand what it is you're posting. I tried to help you, but can't help those who refuse to be helped.
  4. Yes I agree, there seems to be an error with the pitch integrator, which also explains the suspiciously low G onset rate, as well as the odd pause it onset rate when quickly commanding full pitch up above 480 kts or so.
  5. No, you are again using the Ps curve which is for sustained turns only. Diving does not help ITR, it only improves sustained rate by reducing energy/speed loss. This thread concerns instantanous turns, and the DCS F-16 is atm pulling 8.7-8.8 G's ITR at the speed (M 0.67) where it should be pulling 9 G ITR. So the DCS F-16 is NOT corresponding with the real world data.
  6. Yes, he's mistaking STR (Ps curve) for ITR (lift line).
  7. Small correction: According to the official charts 9.0 G's instantanous can be pulled at M 0.67, not 0.66. Ingame however 8.7-8.8 G's is all that can be managed under the same conditions.
  8. According to the real world data 9.0 G's instantanous can be obtained @ ~M 0.66, not 8.7 G's. (Refer to chart B8-48 in the supplements to the manual and follow the lift line) Also no point in diving to achieve instantanous rate, diving would only help sustained rate as ITR is all about lift. You are refering to the Ps -600 curve, which again concerns STR not ITR.
  9. and another one: 6s7XfzAVrrk Again 8.7 G's @ M 0.66. ITRerror1.trk
  10. I am reading G's directly in the sim, not dps from a third party program, and you cannot reach 9.0 G's at M 0.66 @ SL @ 26,000 lbs (DI=50) in the sim atm. Here's a recording & trk file to confirm: 5pzZmjd6sf4 Peak G attained @ M 0.66 is 8.7 G. Std. day, 15 C 26,000 lbs DI = 50 ITRerror2.trk
  11. The FM is my biggest concern atm. The lack of G-onset rate (how quickly the aircraft can build up pitch rate), and the max available load factor (or ITR) can be reached far too late (@ M 0.76 instead of 0.66 at SL according to official performance graphs) In addition to this there's an odd rocking if you quickly pull command max pitch above 450 kts, with pitch rate starting high, then suddenly slows down to a crawl at ~6 G, and then increasing again. It's as if the FLCS is too aggressively trying to prevent an overshoot of the G-limit. (should be able to hit 9.3 G in the horizontal, but ingame you're mostly limited to 8.8 G and at very high speed 9.0) Been bug reporting these issues for a while now, but no change yet. When these things get addressed I'll get back to flying the F-16.
  12. Just thought I report back and say this issue is still very much there with no improvement. At SL I am still only able to reach 8.8 G ITR at M 0.76 when the real thing should be able to hit 9 G already at M 0.66. In addition to this the max speed specific ITR drops when you close the throttle, which it shouldn't as thrust has no impact on instantanous rate, only the sustained one. Really hoping to see some improvements here soon because this is a big error, and I still think it's connected with the oddly low G onset rate the DCS F-16 possesses.
  13. Yep, supposedly the only NATO fighter able to hold its own against the F-22 post merge. (Although the Rafale has managed to beat it too)
  14. As long as it flies like the real thing (within the realm of possibility for a flight sim) I'm satisfied.
  15. Just wondering wether the waay to high sensitivity of the radar antenna elevation control has been fixed for those of us using keys to control it? Haven't touched the sim for a while, so just wanted to know before heading back in next week.
  16. F4U-4 (as on OP pic) would be perfect IMHO as it's both WWII and Korea.
  17. By all accounts the Me262 had light controls right up until around 0.83 mach, after that point it began to become nose heavy, and at 0.86 mach it required a 45 kg pull to get out of a dive unless you used the fully movable stab, which wasn't recommended. Ailerons stayed light though. First class fighter design let down by lack of fuel & trained pilots, and ofcourse engines that for a long time last no longer than 25 hours. Later engines improved the situation, esp. in regards to flame outs & compressor stall due to a new throttle system (MTO also increased to ~50 hrs), but it was too little too late to make an impact.
  18. Actually no :) "The normal range of flight characteristics from aerobatic maneuvres to the stall revealed the Me 262 as a very responsive and docile aeroplane, leaving one with a confident impression of a first class combat aircraft for both fighter and ground attack roles. Harmony of controls was pleasant, with a stick force per 'g' of 2.72 kg (6lb) at mid-CG position and a roll rate of 360 degrees in 3.8 seconds at 645 km/h (400 mph) at 1525m (5000 ft)" - Eric Winkle Brown, Wings of the Luftwaffe, Page 252
  19. Yeah, has happened for a long time. Either they vanish with just their smoke trail continuing, or they bug out at keep going one direction at the same speed infinitely.
  20. Noticed that one cannot attain the ITR illustrated in the F-16C blk.50's performance charts. Specifically at SL I can at most attain 8.8-8-9 G in ITR at M 0.76, where'as the real aircraft can attain 9.0 G in ITR already at M 0.66. Specific condition: 26,000 lbs, DI = 50, Sea Level Track provided below. ITRerror.trk
  21. The problem is still there with the latest patch. Stab movement speed still appears way too slow, and there is a sudden slow down in onset rate at ~6 G.
