I summarize :
Speed vs AA gun/mg (without radar ?)
EW vs IR/Radar missiles
Game code does not care about alttitude but we can "lure" it by the ordonnace carried by aircrafts :
- HD weapons, gun pod, rockets, napalm, light ATGM are typical weapons used for low altitude strike.
- cluster/air burst, heavy bombs need some altitude to have the intended effect or to avoid self destruction
- guided bomb need also some altitude
For example an A-10 carrying Snakeyes and maverick could have better EW (make him harder to lock/detect) than another with Mk82. On the other hand the Mk82's A-10 will flight at higher speed/altitude and make it harder to hit for AA gun's so the SF will be greater.
don't no if i am realy clear
