The Basic Objective of Air Traffic Management

• Enable as many vehicles and vehicle types as
  possible to safely avoid
• Other traffic
• Hazardous weather/airspace
• Terrain and obstacles
• while taking the users most preferred route and
  schedule and by using the most cost-effective
  infrastructure necessary
