Ok. Thanks.

Regarding the sync problems: Cold start: operator HSI not sync, remains at 0º, Hot start: work as intended ARK-15 maybe WiP or as intended, (Hot start and Cold Start), when copilot takes control, ADF in PIlot´s HSI comes to 0º, operator ADF in HSI works as intended. Same when pilot takes control of ARK-15. Tracks attached.mi-24 pilot cold start synch problem.trk Sorry for the helo crash at the end... copilot not synch.trk

Yes. but I´m talking about the "Menory Mode" of the control set. Some documents talk about set the selector in the "MEMORY" position in other to perform a great circle navigation.

Is this navigational mode (Memory mode) implemented? If it´s implemented, is there any guide about how to set the required parameters?

Solved. Thanks a lot. Now EWR can do their job!

Seems related with the "assume control" trigger. Need more testing with the "assume control: equally respnsable".

Maybe user related. Yesterday, I tried a multicrew flight with a friend from a cold start. After doing the procedures, the following problem was observed: The HSI only worked for the "player in control", the other player´s HSI was fixed at 0º, and the needle "1" that mark the NDB direction was also fixed at 0º. When the control was assumed by the other pilot, the HSI starts to work and the former "pilot with control" notes that his HSI is set to 0º. Anyone with the same problem?

I was to post the same. HSI stands in magnetic when powered up and press the sync button.

Some ideas, unfortunately not being able to confirm this. It seems that the Greben (or similar) is/was fitted in helos/airframes that have some kind of "autopilots" (course selectors/ route mode) like the KA-32 civilian models, Mi-26, Mi-17 (before they got western avionics). Helos and airplanes without "autopilots route mode/course selectors" were fitted with GMK-1 or similar. Maybe with "Autopilot", or "course selectors in the former USSR", the Gerben or similar is compulsory? Something like: Set MagVar in the KM-2 (or similar), set the Greben in "tune" mode, set the latitude in the Greben, push the synch button to synch the KM-2 value, set the Greben in oper. mode. Select the operating mode. And we´ve got 3 operating modes, two of them like in the Mi-8, gyro, and mag, and a third one, the HDG (ZK) mode. But with the system WiP it´s a bit difficult to say something,

I think that it´s WiP. If the guard receiver switch is set to on, the receiving emergency signal indicator is turned on regardless there is an emergency signal or not. In the attached file there is no unit emitting in the 121.5Mhz (emergency frequency) and the indicator is turned on when you switch on the reception. Emerg receiver light.trk

Arggggg!!!!!! The gyro 1-2 selector!!!!!! You are right.

I think it´s more like in the MI-8MTV system, independent power on for each ADI.

I´ve had the same problems. It seems that the Gerben-1/KM-2 systens are WiP.

Copilot ADI is on even with the FDI switch is off. Seems that the FDI switch in the copilot cockpit is not tied to the "element copilot ADI" and is commanded only using the pilot cockpit switches. Attached screenshot. Thnaks in advance.

Nevermind it’s only the need of knowledge…. I always try to understand these systems to fly it as IRL.

The mi-24D or 35 flight manuals and ka-32 civilian that uses the same system. I’m struggling with the Zk/HDG position. We need an updated manual….

Thanks. So the Greben is used in this way: Copilot set Magvar in the KM-2. Pilot set the Greben in tune position, set latitude and synch the gyros with the latitude amd magvar settings. PIlot set the Greben in Oper positon and select the mode: Gyro as primary mode, MK as magnetic if needed.

Yes, maybe it’s not functional. It’s in the Greben-1, 3 position switch HDG/Gyro/mag. Above the Oper/set switch to synch the gyroscopes with the Magvar that it’s set in the copilot cockpit, the KM-2. We need an updated manual…

Solved in 10/20/21 update Please close and mark as solved.

I´ve found some information but I don´t know if it´s correct for the 24P. 2-36.2 Course Control Mode Operation To engage the course control mode, stabilize the helicopter on the desired course, set the course on the course selector, located above the hover-course control panel and make sure the autopilot roll channel, the Doppler system, and the GREBEN-1 flight director system are engaged and working properly. Set the flight director system to course control mode (ZK), then press the COURSE lampbutton on the hover-course control panel. The Doppler system generates a course deviation signal using the course setting on the course selector, the current drift angle, and the current heading signal from the flight director system. The course deviation signal is sent to the AFCS flight computer. The computer converts the signal to a roll correction signal and sends it to the autopilot ROLL channel for execution. The correction signal is limited to a maximum value of 15° as a safety measure in the event of failure of the Doppler system. To disengage the course control mode, press the red OFF lamp-button on the hover-course control panel. But I´m unsure until we´ve got an updated manual.

Is the "Gerben mode selector" needed to be in the left (ZK/HDG) position in order to be able to use the ROUTE mode? The ZK position it´s for the "Course control Mode" I think, so maybe it´s necessary for the Route mode operation.

Maybe WiP. It is not possible to adjust the magvar using the KM-2. Due to this, there is a small discrepancy in the HDG show by the HSI. Track attached: free flight caucasus. km2 bug.trk

In single player, call to the IA menu maybe could be done using the Intercom command instead of a separete call. Having the same list of communication options in the intercom menu that in the radio seems a bit odd because there is no use for them. Same applies to the other multicrew modules.

I don´t know if it´s a WIP feature or correct. Select R-863 in the pilot position, you can listen/talk using the R-863. Switching to the copilot position and selecting R-828 from the SPU-8, comms are done with the R-828. Back to the pilot position with the SPU-8 in the R-863 (pilot cockpit), the comms menu are displayed for the R-828. The last position selected by the last "active position" (copilot). I don´t see a "take control" as in the ARK-15 to take over control, so I suspect that in every cockpit pilot and copìlot can use a diferent radio source. P.S. if it´s a bug, same applies to the Mi-8MTV2 module mi24com1.trk

Yes. If the cockpit seal is presurized, you can´t open the canopy (or close it if you open the cockpit valve first). As IRL since the beginning.
