This is the system for evasive manoeuvres in Target Locked On:
Evasive manoeuvring can also be used to avoid incoming missiles.
(this is separate from using chaff or flares, as there's a different system for that)
This type of manoeuvre may be carried out once a missile has been fired. A pilot skill check must be passed. If the skill check is failed the aircraft does not carry out any manoeuvre. If the check is passed the aircraft can carry out any manoeuvre type it wishes.
Once the manoeuvre has been carried out roll 1d6. The target score equals 3 plus the weapons EW characteristic. If the roll is successful the missile misses and causes no damage.
Note that this manoeuvre still has a fuel consumption and speed reduction effect; these are applied during the aircraft’s next activation.
I may try these ideas out and see if they work or are just unnecessary fiddles that aren't really worth bothering with?
