Manual range wheel has functionality

[суховей]

It says here that the wheel is used to manually enter a range of 0 to 1200 meters in the "forecast-track" gun mode when there is no IRST lock.

The plan was to have it range like a circle to the targets wingspan apparently. But the plan never went through and you were stuck using target size dial with funnel. 
 

This is MiG-29B tech manual right?

Translation atempt (AI:

 

"...On the PSC-3I panel (and with data from COLS), the base value of the target B is entered. With the distance input (via a potentiometer), the range to the target is defined within a range up to about 1200 meters. If the system is moved from the stop of the potentiometer, a manual range input is produced, allowing the use of the input distance in the calculations of the range...."

Correct. 

I trust such documents.

Wheel on the throttle was supposed to be used for manual ranging like in WW2 gyro sight. 

The wingspan is entered on the PSR-31 console.

No, AI mistake. 

The original says that if there is no data from the sensors.

Where does this information come from?

Well ED said it was intended for an external base rangefinder, which basically is Soviet speak for moving a circle to match the wingspan. 
 

Thing is MiG-29B technical manual can be wierd. It gets HMS symbology wrong and few other things are “different.” I love it all the same, it’s chapter on coop mode is a one of a kind, but I would look for other sources personally that it was actually integrated in all production aircraft and MiG-29b tech isn’t just saying that because it was intended and dropped at the last moment. It’s almost like the MiG-29b tech writer is a technical genius who didn’t spend a lot of time around people flying it lol.

Ну, Эд сказал, что он предназначен для внешнего базового дальномера, что, по сути, на советском сленге означает перемещение круга в соответствии с размахом крыльев.

Yes, the end of the paragraph confirms this.

Спойлер

The computer should generate coordinates, vertical movement speed, and the radius of the aiming mark. Additionally, the fire line vectors (probably mean "the funnel) should be displayed.

Maybe ED is right and it was never implemented. I need to read more sources of information.

UPD. I read this manual to the end. There is nothing further about this wheel. There is nothing about manual range input in the description of FCR modes and HUD indications.

Pilot said wheel is set up as a fancy 2 position switch. Switches between gunnery vs locked target and funnel.

Does it duplicate the gun's trigger?

These are probably local upgrades by MiG users.

Trigger turns the gun mode, wheel switches between gun submodes.

Funny, target acquisition button switches between a different gun sub mode!!!!!!!!

It's a joke? 

Post was about undocumented functionality of range wheel on throttle, not the lockon button on throttle (If I understand the term "target aсquisition BUTTON" correctly) .

If you press the TDC slew rounded on the stick. If in gun mode it changes to alternate 12 degree lead (cs 6 degree led limit) mode

Ok, you mean  KU-31 depress (on stick) , not lockon button on throttle. KU-31 depress is documented function to change gun mode (напишу по русски - с режима синхронная стрельба, на прицеливание нуль методом) . 

Undocumented range wheel function - is switch between locked target ( режима синхронной стрельбы) and funnel. If I correct understand this posts :

It's post for all to end discussion. 

In Russian thread, real Mig-29 pilot confirm that range wheel has NO functionality. 

[Кош]

Wheel all the way back turns on funnel gunnery no matter what else is turned on and keeps in funnel mode. This was told by Fighter couple of posts back and it's also documented in aircraft's manual. Other than that it indeed has no other functions.

Если повернуть штурвал до упора назад, включится режим стрельбы из воронки, независимо от того, что ещё включено, и он останется в этом режиме. Об этом пару постов назад написал Fighter, и это также указано в руководстве по эксплуатации самолёта. Кроме этого, у него действительно нет других функций.

No. That's not what he said.

Sometimes, he contradicts himself.
