  1. You can try going to the FPLN page on the CDU, then press Direct To, then press the button on the left of the waypoint you want to go to.
  2. They're not implemented yet. The most you can do right now is acknowledge the master caution.
  3. Yep definitely still happens AFCS on in the F model. You'll also speed up a couple of knots when raising thrust in forward flight, and vice versa. ED did mention that coordinated turns wasn't implemented yet, so we might also be missing a couple of other ILCA functions.
  4. Well spotted. ED did mention that the LCTs aren't working yet, so the pitch attitude will be incorrect. The DASH isn't either, which means you'll get negative stick gradient on the longitudinal cyclic. In gist, the stick position to maintain a higher airspeed will actually be aft of the stick position for a lower airspeed. It's quite confusing to fly with this effect as you might imagine, and makes it difficult to maintain airspeed. Edit: @cw4ogden I see what you're saying now. The ILCAS should be doing pitch attitude hold during thrust changes, which requires neither the LCT nor DASH to be working.
  5. Looks like the MFD's trim ball is indicating in the opposite sense. Stepping on the ball in forward flight to correct an out-of-trim condition gets the aircraft further out of trim. The one below the SFD is working correctly though. Hope this helps for the next update.
  6. If you have the VPforce Rhino, go to the Effects tab and check "Hardware force trim" and "Override trim" options. Then bind your trim release button and trim hat. Worked for me to get force trim on the CH-47.
  7. Not sure where you got these numbers from, but I did a bit more digging and found this Mi-24D flight manual from the very awesome Cold War Air Museum (CWAM), link here: https://mudspikefiles.s3.dualstack.us-east-1.amazonaws.com/original/3X/7/a/7ab064a7f951b9f0325354f257f5e58c571936d6.pdf. According to this manual, the airspeed limit for sidewards and backwards flight is 10KIAS, which is very close to your numbers. I've also seen some manuals translated from Russian that state 10m/s, but I'll leave that discrepancy aside for this discussion. So to check out the tail rotor VRS theory I went back into DCS and repeated the test with no weapons and at 50% fuel (so that pedal authority would be less of an issue). I repeated the test but accelerated from hover into lateral flight to the right much more gradually. Referencing the hover speed indicator, at speeds below ~18KPH the Hind weathervanes to the right, requiring left pedal (or rather a reduction in right pedal) to maintain heading, indicating positive directional stability. Once ~18KPH is exceeded, the yaw tendency rapidly reverses, requiring an accordingly rapid right pedal input. Maintaining this flight condition resulted in a yaw oscillation, requiring alternating left and right pedal inputs to maintain heading control. This behaviour is consistent with tail rotor alternately entering and exiting VRS as the heading oscillated, with the according pedal workload. I'm really impressed that this aerodynamic phenomenon is being modelled in DCS! Case closed I think.
  8. It's definitely possible, however that would usually manifest when a certain lateral speed is achieved, so you should still get positive (or neutral) weathervane behaviour at lower lateral speeds. That said it's also possible that the Hind has neutral or negative directional stability when translating right. Without test data to refer to however there's no way to know.
  9. Came back to the Hind after not flying it since initial early access FM release. Did the following test on DCS Open Beta on 2 Dec 2023: Conditions: SAS OFF in all 3 channels IGE Hover, heading perpendicular to the runway Test method: Accelerate laterally to the right along the runway, gradually increasing lateral translation speed towards 100kph while maintaining ground track. Repeat with translation to the left. Result: During translation to the left, the Hind yaws to the left, indicating positive directional stability (weathercock stability). During translation to the right the Hind yaws to the left indicating negative directional stability. Discussion: I've tried to find information on the Hind's behaviour in the low speed environment (such as Trimmed Flight Control Position data), but was unable to, and so cannot verify if the above behaviour is correct. However I find it quite unusual to have such a large difference in directional stability whilst translating to the left vs to the right. Am happy to discuss above behaviour using any real world test data the team is referencing, or help with further data gathering in DCS. Kind regards.
