You get some good aim in your game and shoot where they would be seen, bullets must travel a distance before hitting the target.
It takes a while for the bullet to travel, so shoot a little bit ahead of the jet. In other words, aim for where the jet is going to be rather than where it was. Battlefield has a lot of intricate strategy like this, unlike the Call of Duty games there's quite a bit to learn.How to shoot down jets in battlefield 3?
You have to account for the travel time of the bullet or cannon shell.

So aim where the plane is going to be, not where it is. Put your reticle ahead of it.
You have to anticipate where the Jet is going to be if you shoot to late you cannot aim straight at the target.

you have to land on their run way i couldn't get them in the air so i tried it and it work it takes some time to get it right and u have to try after you land to hit a bush or a tree that will stop you and you move your way over to their planes slowly and shoot them when they get in it works trust me
