-- After the V1.0, which was based in a simple script where, it takes SAMs and switched them off depending on the distances and couple of other factors, i made this V2.0 which is much more advanced and have many other factors.
--The script can be used with a player (A6 Prowler style) or with an Standoff Jamming with an AWACS or E2/E3 style... with the command "startEWjamm(jammer)"
-- Now it takes into account, distances, angles between Jammer and SAMs and Aircraft targeted by SAMs (hereinafter “Target”), jammer altitude, Jammer and Target altitude differences, banking, pitching, and few other factors such as the “dice”.
-- Now it takes into account distances, angles between Jammer and SAMs and Aircraft targeted by SAMs (hereinafter “Target”), jammer altitude, Jammer and Target altitude differences, banking, pitching, and few other factors such as the “dice”.
-- In this script I manage probabilities, and go/no go parameters. For instance, if the bank of the aircraft is too high, it takes into account, if the angle between the SAM and the Jammer... if it is not in the proper position, then, the jammer does not work. Others, such as distances, an altitudes, makes the probability of successful jamming to rise the lower the better... but if differences between Jammer and Target altitudes, the higher the differences, the lowest capacity of Jamming.
-- Now I ll explain all these factors so you can plan your successful mission taking into account what is best for your mission profile.
-- Another improvement is now, the radar does not Switch off. It just goes to Green Alarm state, it means, it does not fire, but is still working. Therefore, as in real life, you only know if the jamming is working if you are not being shot at!!!!!!.
