Hi,
there is hydraulic pressure.
in the attached trackfile it is the first startup with the MI-8. After that i use autostart
Is there the possibility that there is a problem bcause i do the startup from the third seat?

Thats the problem. You cannot control the helicopter from middle seat. You can move cyclic and collective only when you occupy left or right pilot seat.

Hi guys,
I got the Hind in the Autumn sale and have been enjoying it and the Hip since! However since the last patch yesterday I have noted that when in a cold or hot helicopter that autopilot stability won't stay on like it used to pre-patch.
I think it must be a generator thing, because the sight keeps going on and off, along with the fan. The AP stabilisation also goes on and off (or doesnt even turn on in autostart).
I am not doing anything different to before, and my control mapping hasn't changed. So I haven't a clue of this new feature is a bug or intentional change.
Thats usually the problem with handling the collective too roughly. Generators whent off when main rotor RPM goes under 87% and its shuts down the autopilot. You need to be more gentle with collective.

Unfortunately, it doesn't operate as intended. When reviewing the record, the right pilot's SPU is in the HF position (YaDRO-1A radio set), and pressing the left pilot trigger also activates the YaDRO-1A radio set, despite the left SPU-7 bib switch being set to (UHF) – R-863 UHF/VHF radio set. As a result, our logic is synchronized, but the visual display of the switches is not synchronized. And what about ARK-9 and ARK-UD? Where will the arrows on the right and left UGR-4UK point? Anyway there is a bug here ...

Yes, the behaviour when you jumping between seats and you keep transmiting on the old seat radio setted on right SPU7 is a bug. It doesent get to the new setting until you change radio or ICS/RADIO transmitting. Visuals are correct. Internal logic is not synced.
And what is the problem about ARK-9 and ARK-UD? For ARK-UD only the arrow on the left UGR-4UK can be switched to VHF source. The right one will keep showing the ARK-15 frequency

Since you asked to have the other thread moved to Mi-8 section I’ll reply here.
You said swashplate should have tilt by number of blades, 180 divided by 5 is 36 degrees.
And plus the pitch horn offset, equals the angle from which the blade pitch is angled from say, direct forward for a backwards pitch.
Now if I’m translating the technical document on the swashplate correctly, it says that the angle of the pitch lever horn to the horizontal flapping hinge is 72 degrees.
However, it also mentions that the tangent of this angle is the coefficient of the swing compensator. Is the swing compensator the angle we are looking for? In this case, the tangent would be about 172.3 degrees.
That is unless it means the opposite angle, 28 degrees, which would be
a tangent coefficient of about 30.4 degrees.
Not sure if any of these numbers help, or if your Mi-8/171 pilot gave you specific numbers
I cannot give @GumidekCZ specific numbers since I don't remember them because it is not important for me. All I know is gyroscopic precession is not compensated by swashplate because it is not needed. I need to compensate for gyroscopic precession only when I am entering too quickly to steep turn (45 degree turn). If I increase bank about 10deg/s, gyroscopic precession is too small to have any noticeable effect.
Please try to find the exact numbers If you have them somewhere

If this is intended, I’ll be shocked. It is physically impossible to see your pylons.
Maybe there is needed some trimming like you see only black or you will see some broken glass effect... But main goal of preventing you from using sight for missile guidance after you exceeded limitation is done. I believe there is not enough data( maybe I am wrong I just do not have them) for visualisation how it exactly looks like, when you exceed the sight limits.

I believe this is the simulation of damage caused to the sight when you exceeded gimbal limits

I experience the same thing.
What was noticed - in mission editor hot start Mi8 has working altitude hold channel
When cold started - channel doesn't turn on.
Double checked the procedure with cold start tutorial, after the start declared COMPLETE the altitude hold channel doesn't engage still.
it is on current open beta 43704I find a workaround. It seems that hot started helicopter is with collective brake pressed by default when you are hot in air or cold on ground. If you press the button Collective Clutch Lock/Release Button, it will release that button and Alt channel will start working. For cold helicopter you need a bit of playing and maybe pressing the Collective clutch lock button and AP button in same time to start working.

Admittedly, I am far better at how it works in real life than in-game. But I don't think you understood what I was saying. Leaving the altitude channel completely out of the equation, I'm saying that in order to move the collective, you should press the friction release button on the collective, then move the collective, then release the friction release button. I am fully aware that pressing the friction release button turns off the altitude channel. I was referring to what the AI is doing. The AI appears to be holding the friction release button down the entire time, preventing you, as the player, from engaging the altitude channel.
Yes. I didnt fully understand that you referring the AI. Anyway this behaviour of AP is definitly not correct.

It seems like it's treating the collective friction clutch release button as a toggle. It should act like the trimmer button on the cyclic. In other words, it's only pressed when the collective is being moved, in order to remove the friction that holds it in place. Also, you should always be able to engage it on the ground.
That not how it suppose to work. Collective friction clutch release button disengates the altitude hold of the autopilot and only way to reengage it is to press the altitude channel button on control box.

The DCS NS430 can be switched between True and Magnetic - however it's bugged on the Caucasus map and so you should use True bearings in the NS430's default "Magnetic" setting.
Note - although the NS430 can draw an OBS course line as required (on a North Up map), OBS lateral/cross track guidance is broken and guides a "Direct To" path to the selected navigation point (rather than to the OBS course line).
Unfortunately the DCS NS430 is both limited in features and buggy - so you are not making mistakes - rather you are finding/learning workarounds.
While the NS430 looks "pretty", for practical purposes - you should focus on learning how to make best use of the accurately modelled flight instruments (wherever possible) in DCS's full fidelity modules and use the NS430 for cross checks and situational awareness.
If you use true heading you will get nonsense heading with added variation to true heading. Thats why he reporting it.
In other words. When NS430 calls it magnetic heading it is true and when it calls it true it is totaly off number.

You didn't understand my problem, i can not use the heading AP to fly straight at all.
My pedals do not go back to center, they look like this when configured for helos.
null
I can only use the heading AP when the pedals are centered, moving them to a desired position and trimming does not disengage the microswitches.
My stick also has no centering force, i only need the trimmer switch to interact with the autopilot really.
The game needs a logic to have force trim release set a new autopilot center for the stick and pedals.
I understand your problem. It is caused by lacking the possibility to resetting the heading AP by some quicker way like it is in RL with microswitches on pedals. I will make the request... Best way will be probably few options like pedal microswitch keybind or reseting heading channel

I got a dead stick cyclic, and rudder pedals with a hydraulic damper, which stay in place after being released.
I selected "Joystick without springs or FFB" as my trimmer mode, and turned off rudder trim in the special options, similar to what i have set in the Mi-24.
The Mi-24s cyclic trim with these modes selected serves only as an autopilot pause/update function, but in the Mi-8 it looks like it has no function at all.
This leads to the yaw autopilot entering pause mode, since the rudder won't see the new center. Yaw autopilot only works this way, if the pedals are in the center position.
I should be able to have i.e. 20% right pedal, press the trim button, and have the yaw autopilot reengage, since force trim has virtually set a new center, right?
Yaw channel of autopilot when it is on on AP panel in Mi-8 is disengaged as soon as you have foot on rudder pedals because there are microswitch in each pedal. Then the AP heading index goes to the middle position and the AP do not hold the heading. When both (ok all four with MC in mind) microswitches are released, the AP will start to hold heading.
Microswitches in pedals are not simulated in Mi-8 yet, so I suggest you to do not use heading channel of autopilot unless you want to fly straight.

Pretty sure Mi-8 is sane. Since it’s same team, I’m not surprised
On Mi-8 when you press fire button, safety cover is automatically opened.

One other facet: I am 90% certain that, if you hold down the "Left", "Right", "Fwd", or "Aft" buttons, the motion should stop automatically on reaching 0 KM, and resume if you press the button again, based on the manuals for similar but older equipment in other aircraft. So, if you reach a waypoint showing 1.2 KM deviation to the right of track, if you press and hold "Left", and move your attention elsewhere, when you look back at the DISS-15 you'll see deviation steady at 0KM. Pressing "Left" again would resume the motion of the digits and show an increasing deviation to the left of track.
DISS-15 counters don't stop on 0 deviations. It just continues up to 999km where it suppose to stop( I've never tested it because it took pretty long to get there).
Moreover the heading counter drum goes roughly frrom 995 to 365 degrees.
I hope you will have DISS-15 in almost all its crappiness soon

The track is not usable sadly. Was sitting on the ground cold and dark for more than an hour going through my controls. That 15 minutes flight was just after that. I'll post one if it happens again.
People really should. I wish there were more general failures due to wrong handling in DCS. Like engine fire in the C-101EB when you do not obey engine limits. Birds bring at least some unpredicability.
Do birdstrikes appear in the debrief as an event? Would be helpful to analyse this issue.
Just share a track please. It can be still usable

two pages,
zero tracks.
Because it is random and it is problem to get usable track. I was lucky the day before yesterday, while testing weapons in simple mission I've encountered this bug and finally get usable track.
The fire is caused by not resolvet warning about vibration and one of the engines (in my case right) significantly decreases RPM. After a wile affected engine catches fire.
Bug has been already reported.
But if you wisht to investigate here one in simple empty mission where it occurs.-

Do you have random failures enabled?
As you can read in previous post no. I do not have random failures enabled. In other words. I have random failures disabled. As well as birds set to 0.

I can confirm this failure IS random. I have empty mission only with Mi-24 and truck. Payload: Full fuel, S-8OFP2 on outer pylons. I am flying way below max power, no icing. I have no birds and no random failures checked.
It is a bug...

Pitot heat is not anti ice.
I don’t know what Toten is talking about, but it is IMPOSSIBLE to overstress the Mi-24 engines, Mi-8, or Ka-50. The engine governor will automatically cut fuel flow at max temperature. The manual says to only have the engine at take off power for 5 minutes to reduce maintenance over the life of the engine. PilotMi-8 former head of Belsimtek who made this module and is former Army pilot of Mi-8 said you could run engine at full power for consecutive flights and not notice anything until many flights later.
What happened to you sounds like icing. You said you turned on pitot heat but when you get the “ICING” warning you need to turn on “Anti-Ice” by the generator panel by your right elbow. You need turn on anti ice from auto to manual; then flip engine/dust protection anti ice from off to on for both left and right engine. All three switches need to be up for anti icing to work. It’s a good idea to turn on pitot heat at the same time.
Another person said they got engine problems at caucuses. If you go high the temperature decreases. You don’t have to get that high on a usually colder map like Caucuses to experience 0 degrees Celsius and icing.
Be aware that anti icing will cause about a 20% decrease In power. If you need to hover with anti icing your hover weight needs to be 900 kg lower then without anti ice.
Credit for photo is chucks guide, which I heartily recommend
Yesterday I encoutered similar scenario but without Icing. During NOE approach to farp, speed about 120km/h I noticed natasha Say something about left engine. Look on Fire panel no fire or extinguished bottle there. So I doesent care. After a minute I get fire warning and heard bang of extinguisher bottle without any shooting at me.

I wouldn’t say vast majority, it is hard to tell how many Mi-35M had been made. It and the Mi-35P operated by Cyprus/Serbia should be the only ones with fixed gear. I think 1,500 Mi-24V were made and over 600 24P. I believe anything outside the Warsaw Pact was given the 35 designation?
That could be true. Czech republic had plenty of Mi-24D/DU and they get anoter bunch of Mi-24V designated as Mi-35 in 2005.
Russian designation system is pure chaoss but interesting to study.

Strange, and I have Mi-24 pilot saying exactly the opposite thing
Ok it was just chat at lunch. Maybe his meaning of function and mine thinking about it was different. What your sources say?

I asked Mi-24 pilots and damper function is horribly modelled in DCS it should damp the sudden change of pedal movement to softer to prevent dutch roll, no retrimming logical axis when it hits the autopilot heading hold limit.
Speed Hold
in Bugs and Problems
Posted · Edited by DeMonteur
As far as I know speed hold is not installed on this version of Mi-8. It is sepparate switch left of the AP indicator. At least on Mi-171Sh from Ulan-ude. I never heard or read that altitude hold is connected to speed hold also
