  1. I honestly think that we're gonna have to wait until we get a full fidelity F-15C for accurate overstress damage. FC3 simply isn't in depth enough for the task. It's not as simple as just making the wings rip off, because that doesn't happen in real life, barring very* extreme circumstances. *Full load of internal + external fuel, low altitude, cold and dense air, high subsonic speed, and full aft stick were enough to cause structural failure IRL.
  2. The real issue is that, if you wanted to implement a truly accurate over G model for the F-15, you'd have to get into some deeper systems modeling. The adaptive overload warning, hung stores after extreme overload, etc. Also, the max attainable G varies quite noticeably with Mach number, altitude, and CG. It's actually pretty hard to reach that magic 150% load under most normal circumstances. But again, we've strayed far off this thread's original topic.
  3. Yep, landing AoA is when the needle is pointing at the 3 o'clock position. But if you lost the inverter you'd have to use the TLAR technique, something an old glider instructor taught me. It stands for "that looks about right" :D
  4. Motorized canopy? Screw the Hornet, this thing has all the modern features I've ever wanted!
  5. The F-15 doesn't need structural damage modeling because it's extremely difficult to actually break the airframe in flight due to the design of the control system. Sure, you can bend it quite easily, but the same thing can be said about the Flanker or MiG-29. We'd also need to implement the adaptive overload warning (the current warning is calibrated for a clean airframe at 9G).
  6. Yeah, it seems like some sort of screw up involving the keyboard command lua's. It might also be related to the starforce issues (iirc it's messing with the sim's internal organization and causing general havoc) Personally I like your theory the most :D
  7. Which one "feels" the best is subjective, personally I love all of the Belsimtek modules. But again, it's personal preference. In terms of accuracy? F-15, as far as I can tell. Now, before anyone rips me a new one for listing an FC3 plane, believe me when I say I'm surprised too. I could probably write a few pages on my findings but I'll sum them up here: 1. The behavior of the flight control system and how it changes with aircraft configuration is all implemented. The Pitch trim compensator, CAS, pitch/roll ratio controllers, and the aileron-rudder interconnect are among the most obvious. 2. The aircraft's performance matches damn near perfectly with real life. Example: using a NASA proven zoom climb profile, you can reach altitudes very close to those achieved in real life. (110-120,000 ft) 3. The F-15 has very interesting control departure characteristics. From what I've read, it's stable and very departure resistant 99% of the time. Due to the aircraft's very high effective dihedral, certain combinations of angle of attack and sidesslip can produce unexpected and very violent departures. This is modeled in the Sim extremely accurately as far as I can tell. The F-5 appears to have a similar level of accuracy, but the aircraft isn't as well documented as the F-15 so it's hard to be certain. Edit: Wow, facepalm. I didn't read the entire OP before replying so I answered a question that was never asked...
  8. Still SFM. Ground handling is unchanged as far as I can tell. (Zero mass in turns, very fiddly rotation during takeoff, etc). It appears they've re-enabled the old scripted cobra functionality, but other than that I didn't notice any differences in flight dynamics.
  9. Yeah, I think the manual mentioned 17 kg maximum force for the stick pusher. What I was referring to is how exactly you'd implement it in the sim (ie if there's a button or lever to disable it like in the Flanker). Maybe they could have a generic "stick pusher override" button that simulates the pilot pulling with both hands?
  10. Easiest way to tell: Go absurdly fast, press S, and yank. If the wings come off then there's definitely something new.
  11. From what I've read, conventional trim changes with airspeed are small. Great, right? The problem is that there are lots of little things that change pitch trim as you fly. Thrust application pushes the nose up, as does speedbrake extension, and maneuver flaps cause noticeable transients. The elevator is geared depending on airspeed to give more precise control at high speed, which makes it possible to run out of forward stick when accelerating through Mach 1. Other general information: The aircraft is equipped with a 3 axis stabilization system, a slightly more advanced version of the pitch/yaw dampers in the F-5. No fly by wire here. The max allowed AoA is 26 degrees, and there is a stick pusher to prevent the pilot from exceeding this (it can be overridden but I'm not exactly sure how). Precise AoA/G control is difficult at/below corner speeds. If decelerating through Mach 1 while in a hard turn, there is a large tendency to "dig in" and over stress the airframe if care isn't taken to reduce back pressure. At high AoA, ailerons are ineffective and heavy rudder coordination is recommended (even though the stab aug supposedly moves the rudders automatically? Clarification needed). Max roll rate can be as low as 40°/s at high speed and low altitude, which is really, really bad (the F-15 is a few hundred degrees per second in the same conditions, thanks to a much more powerful hydraulic system). Also, roll response is generally delayed/slightly sluggish but "with little tendency to overshoot." TL;DR: Nothing is going to stop you from pulling the wings off. Sorry. So it sounds like the Fulcrum will be no easier to fly than the Flanker. I'm looking forward to it for sure.
  12. Fantastic! I've been looking for some in depth info on the Fulcrum and this is more than I could have dreamed of. Glancing through the first pages, it looks like she's going to be a challenging beast to tame. I love it already.
  13. Windmill hit the nail on the head. The Harrier has a firm deadline that RAZBAM is aiming for, which is rather unusual for a DCS aircraft as far as I know (see my sig). The actual date is under a non-disclosure agreement for (gasp!) non-disclosed reasons... I think.
  14. Ride the green circle all the way down to the runway on final. Once you get to 10 feet or so pull the nose up and ease back on the power until you touch down. My method for speed management is to play around and see what speed gives me the green circle in level flight, then just hold that speed. As long as you're within +30 or -10 knots you should be able to get on the ground in once piece.
  15. The water injection is mostly just a means of increasing max power. In other words, it cools the hot section so it can be run at a higher power setting without damage. (as well as increasing mass flow to some degree) In an emergency the pilot can override this and run at max power without water at the cost of damaging the engine. Keep in mind that this increase is less than 10% fan RPM IIRC. I'd go out on a limb and say that a clean Harrier with half internal fuel in good atmospheric conditions could hover until the fuel runs out.
  16. Sorry for asking such a trivial question, but the stuff we're seeing is very early development progress right? Granted, it is going extremely quickly. A lot of the people I've talked to seem to think that lots of eye candy = almost ready.
  17. FYI, if your only option is to run, the Eagle accelerates like a bat out of hell if you push forward to 8 units AoA. (Visible in HUD NAV mode or on the AoA gauge) A real Eagle pilot said they used this tactic for high altitude stuff but it applies to all situations, as it minimizes your induced drag. Beware that 8 units could be as much as negative 2 G. (The pilot specifically remarked that it's weird and makes very little sense, but it works)
  18. Barring some very exceptional circumstances you can't break the F-15 in real life. The Cobra is 99% PR. In a dogfight you want as much energy as possible and dumping all of it at once isn't a good idea in theory, it's even worse in practice.
  19. Set the MAV as sensor of interest and hit TMS up to lock the target.
  20. "What seems to be the problem" "It hurts when I do this" "Then don't do that"
  21. Turn on manual fuel regulation. (Under the canopy edge, right side) Automatic fuel control throttles the engine down excessively at high altitude.

  23. Huh! I just sorta assumed the F-35 had less than great TWR due to its intended purpose and huge amounts of avionics. (Also the aforementioned WVR losses) I also didn't realize the divertless intakes were that detrimental to performance but it makes sense.
  24. Sorry to interrupt this vital discussion regarding the F-35's L33T K/D... I have always heard of the F-35 having a rather bad TWR (which is believable given its M1.6 top speed). However I've recently had a few people tell me that it can go from brakes off to angels 10 faster than a Viper... apparently this was part of an airshow demo. I am 99% sure it's total bogus, has anyone here heard similar claims?
  25. You must begin flying the helicopter before it leaves the ground ;) I'd say to leave the trim alone for now, its main purpose in the sim is to reduce forces during cruise. In a hover, the aircraft naturally wants to yaw right, pitch forward, and drift right. You have to counter all of these tendencies as you raise the collective. It's not easy by any stretch of the imagination, you have to be completely on top of what the aircraft is doing in all 6 axis.
