Various avionics inconsistencies

[Tarres]

The limitations could be overcome with the "manual mode of the RSBN" and the NDB system IRL is in not way related with the RSBN or the PRMG systems. Systems that are differents.

 

I have no problems flying in Nevada or Georgia with the 39 with the RSBN in manual mode and the RKL-41 system.

 

The 21 had limitations IRL and I think that the way to enjoy a simulation is to known its weakness.

 

Maybe I'm too old.

[Teo]

Totally agree (getting old as well :-)), just trying to understand their design decision.

You can't make a precision approach in IMC with RSBN manual mode though? Still, I think it would be great to have the navaid stations placeable in the ME, to be able to create custom scenarios. I'm thinking road bases here...

[Frederf]

What should be done if more than the native radio navaids are needed that the system should be coded to use both the native stations and additionally internal ones as a secondary layer.

 

So the pushbuttons could be 301, 302, 303 kHz and there might be native NDBs for 301 and 302 kHz but for 303 kHz it is defined not in the terrain but in the MiG airplane coding or as a mission object.

 

In this way all native terrain-based navaids can be used but the airplane is not limited to only those.

 

Then with a realistic set of presets (PRMG, RSBN, NDB) the pilot can choose to change the airplane in ME/MP or at runtime so his limited presets are prepared for the mission as needed.

2.2.3 Principle of operation and types of work

A simplified block diagram of the radio compass is shown in Fig. 2.6

 

2.2.3.1 Types of work

 

Radio compass can operate in three modes:

- Bearing automatic - "KOMPAS";

- Bearing on the hearing - "FRAME";

- Non-directional reception - "ANTENNA".

 

1. Bearing Auto is the basic type of work. In this mode the radio signals are received by the traced loop antenna and omnidirectional. If the radio compass is tuned to the frequency of the radio station the traced, then the tip temperature indicator rate UGR-4UK is automatically set in the position corresponding to the angle of foreign currency radio.

 

2. Bearing at the hearing. In this mode the signal is received only by a loop antenna, and the antenna is omnidirectional disconnected from the system. When the azimuth at the hearing radio compass enables / by rotating the loop antenna via a switch "FRAME L-P," and at the same time listening to radio signals or indications tuning observation / determination of the minimum reception. Note course pointer UGR-4UK points / in this case / angle or the angle of the radio exchange rate, differing from it by 180 °.

 

In the case of joining intense electrical noise, this gown work can be used to modulated signals acceptance conditions for works and niemodulowaych in terms srednicfalowym / reception area code /.

 

3. Reception non-directional. In this mode, the signal is received only by the omnidirectional antenna, while the compass circuit is turned off from work. Radio compass is used as a superheterodyne receiver, working on medium wave, characterized by high sensitivity and interference resistance. This kind of work is used to signal acceptance conditions for works reconnaissance, command, etc.

 

Application of the second heterodyne the ARK-10 allows you to receive both auditory signals modulated and unmodulated / type of work ARK "FRAME" and "ANTENNA" /.

2.2.4 Description of the structure radio compass

2.2.4.2 loop antenna

2.2.4.3 Antenna Amplifier

 

 

2.2.4.4 Basic control panel

 

The control panel contains the following elements:

- The mode switch

- Switch keys (10 keys)

- Mechanism automatic tuning of the engine type "DK-1A", selector switches and lamellar

- Synchro - transmitter initial reading of "BS-1"

- Synchro - transmitter accurate reading of "BS-1"

- Graduation smooth frequency tuning and switch sub-ranges

- Switch turning loop antenna "FRAME L-P"

- Switch "TLF-TLG"

- Switch passband "WIDE - NARROW"

- Knob "Volume"

- Use the but- ton to switch desktops

 

The mechanism of the buttons is built in this way, with the inclusion of a button automatically disables any previously enabled.

 

Pitch frequency is spiral. The length of the pitch after the development is approximately 1 meter. Scale photographic process is carried out separately for each radio compass (individual pitch). On the side of the control panel placed multipin connector transition, to which the inside of the wires are soldered to the console. From the outside to the connector pin transition wires are two connecting cables with a length of 0.5 m, completed two connectors (19 and 30 pin).

 

2.2.4.5 Desktop additional

 

2.2.4.5 Desktop additional

 

Desktops radio compass is on the front panel only 9 buttons to turn the tuning set and the but- ton to switch desktops.

 

The panel does not have an additional mechanism to set their own fixed tuning, and the buttons of the panel are connected in parallel with the base panel buttons. In this way, pressing additional desktop will tune the radio compass frequency determined by the mechanism of the primary desktop for the button with the same designation. The switchable desktops on the additional panel is incorporated in such a system as the basic panel, with the proviso that when it is pressed, the voltage 27 V is being applied to the winding 6-4 and 2-8 P15-1 relay switch and desktops to short series right contacts of the switch.

 

The additional control panel does not have a switch: the type of work, passband and TLF-TLG.

 

2.2.4.9 Counter distance

 

Counter distance consists of the engine type DID-0.5, synchro-receiver type SEM-1, 3 drum counters and regulator.

 

Meter distance is a display unit. Indications distance, be read by the instrument's window with drums, on whose numbers are applied.

 

2.2.4.10 Remote Switch waves

 

The remote switch is a separate waves. For this switch Each number buttons correspond to two positions marked rzymakimi numerals "I" and "II". According to the instructions operating instructions, further radios leading airport landing fixed odd desktops (1,3,5,7), while closer to leading radio - buttons (2,4,6,8). Switch waves PWD before the flight is set at a position corresponding number button, which is set closer to the radio station leading airport landing.

 

2.2.5 Start-up and control

 

Starting radio compass is based on the sleep self-AZS-15 labeled ARK in the first cabin on the right panel and set the mode switch in one of three positions "KOMPAS", "ANTENNA", "FRAME".

 

Control of radio compass is done with the control panels. It includes the following steps:

 

1. Inclusion of radio compass by setting a switch, the type of work in one of three positions "KOMPAS-ANTENNA-FRAME".

 

2. Tune to any frequency by adjusting the swivel "switch to" and knobs "TUNING AWARD" and "TUNING SMOOTH" (after you press marked with the letter "P") in the appropriate positions.

 

3. Tuning receiver defined and previously set frequency, by the push of a button. Radiola-tarniom closer corresponding buttons marked with even numbers (2,4,6,8) and "CONTINUE" - the odd-numbered (1,3,5,7,9).

 

4. Changing the passband of the receiver is achieved by setting a switch, "WIDE-narrow."

 

5. Switching terms of work radio compass is followed by the setting of a switch, "TLF-TLG."

 

6. Adjustments to strengthen the receiver under "ANTENNA" and "FRAME" and the volume control on the headphones at work in conditions of "COMPASS" is achieved by turning the "REG. Volume. "

 

Fig. 2.9 Control panel radio compass ARK-10 in the second cabin of the aircraft:

1- keys with which retunes to the frequency of the radio compass predetermined; 2 button to switch desktops; 3 indicator lights (red)

 

7. Pedestals control loop antenna under "FRAME" is achieved by a switch biasing labeled "FRAME L-P." Loop antenna rotates as long as the switch bias is pressed.

 

8. switching the control operation of the first radio compass from the cabin to the other by pressing the "switch desktops" on the control panel in the second cabin.

 

On the control panel in the second cabin (Fig. 2.9) is located the switching control panels and nine keys with which you can select one of the previously tuned frequency radio compass, and which fully correspond to the button main desktop control, in the cab of the first (even 2,4,6,8 keys are tuned to "closer" beacons, and the odd 1,4,5,7,9 - on beacons "NEXT").

 

In addition to a switch, automatic (UAP-1), which retunes radio compass with frequency "closer" beacon on the frequency of "EXTENDED" and vice versa, on the plane there are manual switch "closer-FORWARD" (emergency control system in case was damaged UAP-1 ).

 

Standoff switch wave (PWD) allows the top tune on the radio compass frequency beacons "closer." It is connected in parallel to the buttons even console.

 

On the desktop imitator damage IP-K is located potentiometer, which in Fig. 1.5 is marked with number 20.

 

Imitation damage radio compass ARK-10 the potentiometer knob, marked with the inscription "ARK" on the desktop imitator damage IP-K. In this case the two phases synchro - transmitter mounted in a block of directional antenna radio compass ARK-10, and synchro - receiver mounted in the UGR-pointers 4UK, are connected in series potenojometry of resistance of 500 ohms.

 

It seems that inner and outer beacons are placed preferably or necessarily on even pushbuttons for inner and odd pushbuttons for outer. This also matches the idea of the the remote wave switch choosing the inner beacon since it is is marked normally 2, 4, 6, 8.

HI Frederf,

 

Thanks again - that's thrashed that out!

 

Finally, just to confirm... you're saying the green inner beacon automatic tuner light (as per my OP) never comes on in the game?

 

 

 

Since you borrowed my screenshot, used in a previous thread asking about exactly this. Couldn't you have bothered to actually read the answers in the thread as well? :music_whistling:

It wasn't supposed to be rude or anything like that. As always it is never a good idea to be ironic or make jokes on a forum, escpecially if it isn't in your native language.

Neither did I notice that your post was edited.

Fair enough mate - thanks for the use of your image :)

[Tarres]

Frederf, the 21bis uses a "command console" a bit different but I think that the ARK-10 works in this way (based on the Flight manual and the equipment manual):

 

9 "presets": the pushbuttons. For the airdrome markers, they store the "OUTER" beacons, or NDB stations.

8 "bands" for the "Inner markers":

I. 120-280 kHz

II 280-440 kHz

III 420-580 kHz

IV 580-740 kHz

V 720-880 kHz

VI 880-1040 kHz

VII 1020-1180 kHz

VIII 1180-1340 kHz

 

With a outer beacon selected, pushbutton depressed, set the "rotary" to the proper band. The Outer/inner control switches from one to another.

 

 

Imagine that we have a proper ARK-10 system, modeled:

 

Example:

Anapa 215/443

 

in the ME, we set the 443 into a "presets box" (like the ark-22 of the KA-50), channel 1

 

In flight, we push the "1" button and the rotary in the "I" position (215 is the inner beacon frequency, so "I" is the correct subrange)

With the inner/outer selector we can change between them.

 

NDB beacons, like Dzhugba for example, are set in the "presets box" of the ARK-10 in the ME, in this case the "rotary" is not necessary.

Example: in a "presets box" we set "420" in the "2" and in flight we push the "2" button and we have indication to the Dzhugba NDB.

 

Sorry for my english.
