Curious as to why EECH always with crosscoupling on when you disengage autopilot takes a split second for the crosscoupling to actually engage, causing a yaw. If you turn crosscoupling off, you'll notice what's going on in the former.WOW!
Translational Lift value is reversed when FM 2 is in use -- on is off, off is on and explains some of the FM 2 lift issues since at least 1.15.2 -- not to mention way too weak in FM 2 now even when you activate it with OFF. Just as notable, though, is that ground effect has always been too weak in all
the EECH FMs.
You already know the Hokum yaw is too weak in FM 2 and about twice what it should be in FM 0 & 1.
In FM 2 I'm also getting bizarre yaw and rolls when trying to taxi in a Comanche with the wheel brakes off that's basically making it impossible to do a proper taxi... maybe an issue with this wheel suspension mod stuff.
1.16.1 has some crashes, but not the repeatable one that happens in 1.16.2 when I roll inverted in a Comanche on some maps.
The previous/next target both cycling in the same direction bug is also present in 1.16.1, so might be quite old.
Putting the main rotor lift to at least dmrl=1.1 in the EECH.ini when FM 2 is in use seems to have met the minimum single-engine lift requirements for many of the helos just barely with an average loadout, without wildly increasing ceiling and top speed. In fact, it seems to approximate published Comanche dash speeds when briefly at 100% torque on two engines in level flight now. At dmrl=1.1 even the Hind can just barely make it back to base on one engine without starting on fire most of the time, which is a pretty good litmus test, I think. It's still a problem with max gross weight situations, though, and we'd need a jettison stores function for this alone to be sufficient. I suppose next is further dealing with the taxi wheel rolling problem, fixing the still-anemic translational & ground lifts and coaxial yaw rates, and raising the speed for when turn coordination begins kicking in remains on FM 2 to be at least as good as FM 0 & 1, but with the added nifty new RPM effects and proper turning at speed. I am also curious about what the global air density modifier does, as adjusting that solely before made zero difference on the IGE + ETL problem during failure of one of two engines that I could tell.
The dyn files are not increasing the coaxial yaw rate except on the helix, which seems to be just an Apache A with a cosmetics job. While on FM 0 & 1 the EECH.ini dynamics stuff does something, nothing except the main rotor lift line seems to do much on FM 2. Regarding FM 0 & 1, the tail-related dynamics stuff in the ini is having some bizzare effects on lift that's completely unrelated to the tail, and the drag one oddly increases coaxial rotation rates on the Hokum and Shark. I believe some of the problem with all the FMs is the result of an attempt in the code to do a yaw damper with inherent tail drag, but obviously if tail values are also weirdly affecting lift then there are some bigger problems at play.
I vote also for jettison being made ctrl + J.
Copied from https://SimHQ.com/forum/ubbthreads.php/topics/4551698/re-flight-model-or-where-is-it#Post4551698
1. Make my ini Dynamics tweaks the default... including the comments, like dmrl at 0.9 for FM0/1 and 1.1 for FM2. Obviously when some of the below stuff is done, some of the explanatory text will go.
2. Fix Translational Lift option when FM2 is in use. Currently, on is off and off is on. Some people may choose to use FM2 with its bizarrely-weak Ground effect and Translational Lift even when it’s properly on, so might as well get that option setting working correctly. It’s also possible that in the long run this model might have more potential, such as with more stable yaw pedal performance, but only time will tell. (Edit: the ETL coding for FM 2 is very broken, as it's actually altering lift while in a hover)
3. Muted yaw on coaxials in FM2 needs fixing next. Makes them and much of FM 2 basically unusable right now.
4. Fix rotor brake engaging when you jump into an aircraft already in flight. Autopilot also sometimes is off. Falling out of the sky abruptly could be categorized as a FM problem.
5. Vibration from extreme cyclic and also on extreme coaxial yaw changes, so like from -1 to 1 of the roll axis in a split second would apply most vibration, and that same amount slower or a less amount just as fast would be less vibration induced briefly. Have it IAS-compensated, too, like the current banking angle vibration is, which is a good thing, by the way. Coning effects from just holding a bank causes some vibration, so don’t get rid of that. Edit: On the vibration, I forgot to add to the list the part about it needing to happen additionally moving in and out of ETL.
6. Main rotor damage from the more extreme #5 for longer lengths of time. Less length of time means less chance of damage. More extreme handling requires less time to cause damage. First instance causes some damage and main rotor oscillations, continued extreme handling after a few seconds of oscillations or another instance causes loss of main rotor. The damage and vibration threshold could lower when you are already damaged. Obviously the vibration and noise will be a warning this might occur before the first instance occurs.
7. Try to put RPM effects from FM2 into FM0/1, or at least make similar RPM response effects in FM0/1. The RPM effects in general need be greater even in FM2, so more sluggish RPM response and opposite effect even with very large and fast collective changes. Excessive RPM and eventually damage with rotor disengaged is already occurring with FM2. Rotor engaged effects are too slight right now, though. In general, RPM and lift needs to also increase sooner when you lower collective and nose down with rotor disengaged. During autorotation you manage RPM that way immediately, while currently there’s a lag for the first few seconds and you require a ridiculous amount of IAS and altitude loss to get the RPM to start increasing.
8. Add an axis in-sim for yaw scaling for people that don’t want to use PPJoy/GlovePIE. All the way to one end and you get normal full yaw available on the yaw axis, other end of axis and you get some fraction. Probably bringing the axis that’s been smoothed and added 2 then to the power of 1 is sufficient rather than a power of 2, which gives you a divider of 1 at minimum (the original axis), around 2 on the center of the axis, and a divider of 3 at max attenuation. A power of 2 for 1 of the axis itself plus 2 at max gives a divider of 9, which is excessive unless you’re doing crazy stuff with the ini yaw drag and acceleration Dynamics.
9. Yaw is too fast and ramping up on coaxials on FM0/1. The most extreme yaw rates in a hover are related to an acceleration or ramp up and increases dramatically after extended continuous pedal. It appears worse with higher altitude or collective. While yaw drag should not be mimicking yaw damping and yaw acceleration is really the wrong value to be adjusting, I don’t know how much of max yaw is dictated by the GWUT. A separate yaw damper parameter may be necessary. The only current damping reference in the source code is on wheel suspension.
10. In FM 0 and 2, auto coordinated turning mixes in too much yaw at low an IAS. Turn coordination needs to not occur until well into translational lift, and then only more slightly at low speed and to keep FPM centered during bank at higher speeds. 50-60kts is usually a good threshold. Right now on FM 0 and 2 it seems almost completely proportional to banking regardless of IAS or direction as if it's an inherent part of the roll physics independent of the aircraft's own yaw capability, making side slipping in a hover impossible without counter yaw, which is difficult to do predictably, as well as adding to yaw capability. So, for instance, on FM2 with coaxial helos, you clearly get more yaw by rolling than you do with the pedals. There should also be no turn coordination when going backward ever. Of course FM 1 doesn’t have a lack of ease of side slipping when in a hover...
11. FM 1 should really just be FM 0 without coordinated turns. The yaw streamlining when in forward flight is too weak right now to be remotely realistic in FM 1, though its current lack of coordinated turning is slightly useful considering the current ways it mixes in too soon in FM 0 and 2. Hypothetically, FM 1 could simply be removed completely if Auto Turn Coordination became an in-sim options setting like Translational Lift and Ground Effect are… assuming #10 can be done. In contrast, the only reason ETL, GE, and RBS are in-sim settings were so people could turn them off and see how deep the EECH flight model was. It is not easier to fly without ETL and GE, as should be glaringly obvious to anyone trying the current FM 2 with Translational Lift set to "ON" (actually off).
12. Zulu Cobra needs its max IAS and RBS threshold raised. Most other helos need it slightly lowered, but for the meantime I’d probably leave the others where they are.
13. Taxi yawing in FM 2 is not working right, as there seems to be weird force moments occurring, possibly related to the suspension mod interacting with the ‘alternative’ FM coding mod.
14. Ensure wind is part of IAS calculations when there is a headwind or tailwind. Not sure if it is.
15. G-forces head movement is too slow to move, especially on returning back to center.
15.1. Also, if G-forces are monitored on the aircraft, this would be useful for better affecting the sound of the rotors and vibration currently, as some of the ebbing of the sound is reminiscent of the rotors unloading at the top or beginning downward portion of a parabolic ascent, but the timing currently seems somewhat off.
15.2. Crosscoupling is momentarily off when disengaging autopilot.
15.3. There's still a bug where rolling in a, especially a Comanche, will cause a freeze in 1.16.2 while you're inverted.
15.4. Engine power (or I suppose collective pitch or lift calculations themselves) needs to be exponential or log, such that at 30% torque you're getting the equivalent of about 50 or 60% torque that we're currently getting without increasing the maximum available power. It shouldn't take so much torque to taxi (30% torque should be enough) or lift off with the combination of IGE & ETL (more than 30% torque but less than currently), but obviously we don't want to increase total max available lift or power beyond what we're currently getting with dmrl at 0.9 to 1.1 and the global drag at 3.0.
15.5. Hover hold with no altitude hold (where you manually control altitude) is causing collective, torque, or lift calculation issues (or maybe it's only including one engine) compared to 'stable' hover hold with altitude hold that agrees with full manual hovering.
15.6. Translational lift is still too weak in FM 0 & 1, though other values like global air density will have to be changed from 3.0 when it is fixed. Something like a fully loaded Hind should not be able to lift off without ETL, but ETL is too weak currently to provide enough benefit to fully compensate. Obviously FM 2 has ETL and ground lift even weaker than FM 0 & 1.
15.7. While it's too easy to get into VRS right now without tweaks, it's also too simple to get out of. Going to 120% torque should not get you out of a VRS if you still haven't gotten lateral movement, and you shouldn't be able to regain all cyclic authority until either you've at least reduced collective a little or already gotten out of the VRS somehow (wind, moved the cyclic in the direction opposite of the pedal required to keep a heading when adding power, etc). Going to 120% torque briefly is not the solution to VRS, in fact it should make it worse if that's all you do.
15.8. FM 0 & 1 have broken crosscoupling OFF behavior.
15.9. Nose pitch currently changes when in a stable hover hold and you switch FLIR on and off.
15.91. RBS should shift lower below Vne with added weight and higher G-forces.
15.92. Like to have random oscillations and vibration when near and behind other aircraft, based on front aircraft's size (total weight as proxy).
15.93. At highest altitudes, low density, and/or high temperatures, the engine compressor stages should reach their limits before you overtorque. Compressor stage performance is the limiting factor of max cruise altitude, not torque. Obviously at lower altitudes and temperatures, the current method of over torquing first is appropriate.
15.94. The Kiowa may have its RBS happening slightly too soon but definitely has way too much power such that it's very easy to reach the never exceed speed. Some of its analog dials are also giving wrong quantities..
16. Later on we can figure out a way to add my GlovePIE scripts into EECH so people have to do less setup. I will work on having three control modes where you double tap the trimmer button to change to each with a voice telling you the mode. First will be the current default pitch and roll wings level mode with manual trimmer. Second mode will be same as first but with auto trimming of pitch. Third will be full dynamic auto trim like the above posted scripts.
17. As for FM stuff off the top of my head, the final step before a complete rewrite of the FM code of EECH would be simply to find a way to stop the continuous roll that occurs past a certain roll angle. That way you could roll inverted, stop applying X axis, and it will stay. Right now, past about 0.40/-0.40 on X, you get this continuous roll. So when you are finally inverted, you have to deflect a bit back in the opposite direction to hold the attitude rather than just release stick pressure. This appears to be part of this artificial wings leveling it’s doing.
Non-FM wish list stuff:
18. I would like a view mode that keeps the FPM in the center of the view as you maneuver.
19. Calling in artillery or air strikes don’t seem to be working. Not sure if that’s actually a bug or just a misperception on my part.
20. AI helos landing on top of helos.
21. Carriers don’t seem to be protected by CAPs or the rest of their group ships very well.
22. The game’s low-level foot of its contrast curve or gamma seems off, like you’d need a pro-quality CRT or an OLED to see any detail in shadows. I don’t mean just at night, which by the way I turn down to 0.3 darkness usually in the ini to make the NVG necessary. The gamma just seems oddly skewed. I can sort of adjust for this with my monitor or with NVidia settings, but it might be worth checking out.
23. The ability to change the amount of dust or have the dust change depending on environment. Deserts should have the most, obviously, and are fine where they are, but most other environments have too much dustout effect. Maybe use the same flag as clouds not being in deserts to have them get the full dust out and everywhere else get 50% of that amount.
24. Add jettison stores. Ctrl + J. Useful for increasing lift after engine failure.
25. Previous/next target both cycling in the same direction bug is also present in 1.16.1, so might be quite old.
26. Escorts are being assigned way too late.
27. Recon mission transmission allowance needs to be much further away from X. For that matter, any helo should be able to transmit recon data whenever you want to update the campaign map.
28. Jumping into a landed helo at a FARP to start a mission that you have to activate the rotor and its gear is retracted with ongoing multi systems failures.
29. Swap the payload menu Hellfire L and R designations back from their technical designations to the original designations (L for laser, R for radar) the game used that are still used on the HMD and MFDs.
30. New issue in 1.16.2 where the sound stops working until restarting EECH.
31. In some campaigns you irreparably become immortal, with infinite weapons and fuel, and must restart the campaign.
32. The horizon is too bright at night when it's not just before dawn or just after dusk.
33. Wingmen need to employ weapons using their longest-range weapon at standoff range when told to hold position and then are ordered to attack a target.
34. FLIR targets need to be saved.
35. All detected targets should be shared between your flight as if there is an automatic data link, at the very least for the heads-down situational display, which should be able to be utilized for at least targeting Hellfires and aiming an aircraft's own FLIR.
36. SAM engagement envelope should decrease probability of acquisition at very low altitudes and/or at low altitudes when you're directly in front of a hill or objects. Currently you can get shot down by radars meant for airborne targets even when you're landed and even when you're landed right in front of a building. The only radars that should be capable of discriminating such a landed target is a radar meant for ground targets.
37. Ground and object temperature values for FLIR and IR missile homing. Include burning objects and sun angle in IR homing.
38. Vikhrs sometimes just fire into the ground repeatedly even though a target is properly lased.
39. Comanche can damage its tail on ground contact too easily.
40. Besides the Zulu Cobra 'Viper' needing higher top speed, its gun should only be holding 750 rounds, not 1345.
source code for Comanche, SupCobra, SeaCobra, and Viper: #define NUM_CANNON_ROUNDS (1345)
41. Comanche radar mast is too short.
42. The same message should not be sent by one AI unit more than once in a row. If it's the same message that unit previously said, that comms should not be sent again, such as "Python 1 seeking firing position" over and over.
43. Flight path marker and horizon line on HMD does not adjust with changing HMD pitch.
44. Allow us to choose NVG color (green, orange, original different ones for sides, or grayscale) and IR mode.
45. Hind vertical speed needle disappearing.
46. Be nice to have a marker on the situational display of where your EO/FLIR system is currently locked.
47. Turn to target with H in EO display and target locked should work even when there is no target locked, even when not in hover, and needs more yaw authority.
48. Damaged hydraulics could gradually degrade based on how much change occurs in the flight controls, from one extreme of that axis to another as the above added vibration characteristics would be tracking. More gradual and slight control changes, such as slower banks, would cause less reduction of hydraulic pressure over time. A hydraulics page could show pressure. As pressure decreases there could be more control delay. As controls are moved, pressure gradually reduces. Damaged hydraulics can cause a tendency for the pilot to try to overcompensate which can cause pressure to drop even faster. When hydraulics are damaged, it is essential to be gentle with the controls and patient with the response of the aircraft to preserve control authority until RTB and landing.
49. A pilot roster and search & rescue operations.
50. Smarter overall AI with AI pilot skill that improves over time with experience.
51. Be nice if AI didn't fly through trees, even though they are invulnerable to them.
52. EO system keeps randomly unlocking targets, also seems low-capability on some helos.
53. Ground stabilization doesn't seem to be working well even when set to 1 in the ini.
54. SAMs have an infinite magazine. That's a problem.
