Input needed: Over Berlin - Airplane Dogfighting Game

I thought that weather could be a continuous modifier, my idea was mainly wind, being that if you fly against the wind you move at half speed, as in if you were to turn against teh wind instead of turning and moving , you would turn adn stay in the same spot? maybe. I considered a rain mechanic to lower visibility, so instead of having the capability of shooting 3 spaces away, it'd be limited to two. My biggest concern is the same as yours, it might skew the time capabilties, i thought maybe i'd add it as an alternate rule set and have people if they want it use their own dice. I feel like with the gas tank mechanic and keeping the board small people will have a hard time "turtling" because the ammount of movement cards that are available to the player are definitely not enough for him to make it all the way around the board. The deck set-up i was thinking of is this, player gets 20 cards to their tank regardless of which plane they are, 10 of those cards are just straight movement cards that everyone has, it lets them move forward or forward right/left, but not make the sharp turns, the other 10 cards are divided between maneuvers (like barrel roll, that would place you on the next line over facing the same dirrection, loop that would move you backwards two spaces, 180 degree turn that would keep you on the same tile but reverse your direction, and sharp turn, that lets you move straight right or left), other then the maneuvers you can get weapons like (cluster bombs that lets you damage everything within a radius, like your target square plus everything adjacent, heat seekers that if you play em and keep your target in light of sight on your next turn as well they'll fire and you cant miss, and a couple of things like armor piercing ammo, flammable ammo {this gives me the idea of making certain weapons and maneuvers less effective in certain weather conditions} armor piercers could possibly hit through multiple enemies in line of sight) One thing i thought is doing a card value mechanic, so regular movement cards are worth 1, weapons and maneuvers are worth 2/3 depending on the effectiveness of it, and your "gas tank" could have up to 25 points, i think this would add a lot to the replayability of it. I thought about adding some sort of dice mechanic but i'm getting the feeling that random card drawing is enough, especially since players will have 3 cards and one needs to be played every turn. Keep these ideas coming, weather could be great. I think it'd be hard to incorporate, so maybe I'll hold it off as a possible future addition or maybe an expansion.
