The real trick is your angle of approach
Firstly you can scout where the enemy will be from a safe height, your fast they are slow odds are they be in a similar spot when you come back
Second attack runs should be from either the side or behind where you forces are attacking, for the simple reason they unless somone gets a radar ping they rarely if ever look left/right or behind them to check the skies, this includes AA most of the time they look ahead so they can snipe mechs while waiting for a soft aero to pop in.
And lastly radar , active radar gets you killed , period , passive radar gives you a 50/50 chance

as reommended above dumbfire weapons are best since you need never turn on your radar
if you want to use the 80LRM boat look for stationary target and fire in passive mode without lock, they won't get a missle warning so chances are they won't move if they're already standing still.
and ONE volley per run, don't get cute and try for 2 it'll have you in close enough that thier active radar will see you even though your passive and your dead.
And lastly, if they are spamming AA units don't get pissed and slam your head against a wall, grab the biggest mech you can buy with a high dmg alpha, passive radar and walk behind enemy lines and smack those AA units right in the face , and keep doing that until they get tried of it and swap back to mechs, in which case you then go back to air hehehe
