2. 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 user’s most preferred route and schedule and by using the most cost-effective infrastructure necessary
