Best route in my opinion would be to go hard left from the FOB and up the valley, hug the left side of the map and shield themselves with the mountains.

Area around the main is completely open so it's super easy for the Pilot to spot if the area is full of little moving dots when coming in. From what I can tell, the bots seem to be only interested in NE / E side of the base and don't go other ways, giving the pilot a perfect little mountain corridor from NW side to use for rapid take offs / landings. The idea is for the pilot to take- and fly off as quickly as possible. Going directly towards West means that he would have to climb the mountains over there and If he is to remain to gain altitude over the main, then there's a high chance that he'll get shot down since AI has around 99,9% accuracy against choppers that are less than 200m off the ground.

At the beginning of the deployment we do not have the time / luxury to have defensive squad set up prior to take off. Deployment of Hater's and Double's squads must be done quickly and without any delay.

Since there aren't any other vehicles on our team, we can use the AI mechanics to our advantace, meaning that the pilot has around 4-5 seconds to land / take off before any of the RPG guys become a threat. After the initial deployment, it is up to the Pilot to keep the bird safe using whatever means are neccecary. 

There are many loopholes that are done / left on purpose in the plan to keep the map interesting. If we wanted to have a boring easy-win round then all we would have to do is to deploy everyone in the main, poke the guns out of the bunkers and pew-pew-pew for the next hour or so. My main idea was to set up different checkpoints and FOBs on / around other flags and then, depending on the situation, maybe simulate the evacuation of the FOB base so the bots can take it and progress on to other flags.

Sorry TEDF I didn't mean to say turn left into the mountain but was looking at the valley corridor to the NW off the FOB, which is the same one your path uses on your map, the only difference is that I would be hugging the left side of the map once I got through that valley. So yes I agree the first few minutes should be safe but I was looking at the return journey and subsequent flights in and out of the FOB. Depending on how many bots are attacking the base at any time, it would be pertinent to keep the communications up as to whether it was safe enough to land. As  you say its going to be critical for Double and Hater to establish FOBS, and not lose the Chinook early. Looking forward to those maps, at least you have a battle plan which is excellent!
