IFF how does it work in real life on M2000C

[sunski34]

Hi,

 

on some french video on YouTube, people said that IFF used two instrument parts in the cockpit :

 

• One, just behind the joystick, which is used to program the onboard IFF (transponder)
  
• One, on the left side, which is used to select only the IFF scan, the four digits display the current IFF (or transponder) of the locked target. So thoses digits cannot be changed by the pilot. Actually, this part is used to program and select IFF on board
  

 

So what is the real implementation in M2000C ? and why the part behind the joystick isn't implemented ?

Thanks you for your answer.

Hi,

 

So what is the real implementation in M2000C ?

The one you described. A transponder and an interrogator.

 

and why the part behind the joystick isn't implemented ?

Because DCS doesn't emulates transponders. IFF queries are replied to depending on the coalition of the aircraft.

Thanks Azrayen ;)

 

So actual implementation in this module is good, that is correct ?

 

As I understand, IFF works with mode 4 in DCS (liked to coalitions). When playing, we set the digits to 9000 ... If you know how it's work, can you explain a little bit the process or give me a link ?

In DCS the only thing to do to make it work is to turn it on, no need to input any digits.

When playing, we set the digits to 9000 ...

The digits are for modes 1 and 3. No use with mode 4.

And you shouldn't be able to have a 9 figure. IFF use 0-7 for each digit.
