Feature request title:
Snow Plows and Snow Effect on Runway
Description:
Snow will have more effects in game. Player airport requires snow plows to plow the snow out of runway during winter times. Plowing taxiways would cause more trouble to gameplay so this suggestion should be stay within runways only.
- Like how it is on annual temperature, latitude of your airport has effect on amount of snowy days player gets. On equator, you get zero snowy days.
- During gameplay, snow piles up on runway and after a point runway becomes unusable (like how runway repair works)
- User could select to plow a runway before piled up snow reaches to the critical point.
- Snow plows park on vehicle parking lot or vehicle depot. During plowing operation they drive to runway via service road or taxiway.
- Small runway requires 3, medium requires 5 and large requires 7 snow plow vehicles. They plow the runway right next to each other.
- During snow plow, runway is unusable. So other flights have to use other runways or have to hold.
- After snow plow, vehicles park at their parking lot or vehicle depot to wait the next plow operation.
Side note: This development can be used for other features such as;
- Runway check: Service vehicle goes to runway via service road or taxiways > close down runway for some amounth of time > service vehicle drives along whole runway > at the end vehicle exits runway and drives back to the parking lot.
- Runway repair (which is currently a mouse click): Same as runway check but with heavy equipment and longer closure time. Maybe construction vehicles such as concrete mixer, asphalt truck and some dump trucks could be brought from outside world (like garbage trucks). When their job is done they leave airport area (like garbage trucks)
