A simple radar for a somewhat detailed cockpit. You can use it as a subassembly (just don't forget to copy all the variables from the dedicated tab), or you can build your cockpit around it. It is completely stock, except for some parts, which are scaled way down.

The radar itself turns on with an "ON" button (That's totally unexpected :) ). The dot will light up and you'll see a cross on the screen, referencing the aircraft location. At the top left corner you'll see the "SCAN" sign, indicating that the radar is currently showing your target on a flat 2D plane, with a 360° sector of view (Basically, up is in front of your airplane and down is behind your airplane). The second mode is "BORE", which can be activated by pressing the "Mode" button. In this mode you'll see a vertical line on the screen, referencing the center of your aircraft. The dot will show the position of your target just like you would see it from the cockpit. (Basically, it's a sight mode, to fire guns more accurately.) In this mode there will be another sign at the top right corner. "Wide" is the default, indicating that your sight field of view is wide(approximately 30°), and the "Narr" is a narrow field of view for even more accuracy. (I suggest using narrow mode only when the target is far enough, because of its sensitivity.) To change the field of view, press the Sc. Res (Screen Resolution) button.
The last thing is automated measurements, which provide information about distance "D=...." and heading "H=...." to your target. You can turn them on by pressing the "Calc. F" button. If no target is selected, the readings would say "Unavail".

P.S. I thought about building a complete plane with this radar, but eventually scrapped it. So, feel free to use this on your creations.
