The blue and red bar underneath of the left hand MFD is your ECM gear. The more red you see, the bigger your radar cross-section, and the more likely you are to be detected. The bars that show up occasionally are enemy radar pulses in the area; the longer the bars, the more powerful the radar. If one of the bars touches the red section of the display, you will a beep and the EMV (Electro Magnetic Visibility) warning light will come on. Take one of the following steps immediately to reduce your radar cross-section:
- Reduce your throttle; 60 to 80 percent should be good. Be careful not to stall!
- If you are in a steep turn, ease it a little, or level out com- pletely
- If your bay doors are open, shut them (press 8). You will know the doors are open if the BAY light is flashing
- If your radar jammer is on, turn it off (press 4). You will know the jammer is on if the green RAD light is on
The ECM warning system
If none of these things work, then when you hear the second or third beep, press 5 to deploy a decoy. With luck, the enemy radar will track the decoy in- stead of you. Without luck, the enemy won't buy it, and the TRAK light will start to flash. Now you're in big, BIG, trouble.
This brings us to the subject of missile evasion
