Draw a class diagram to model a system for management of flights and pilots.
An airline operates flights. Each airline has an ID.
Each flight has an ID a departure airport and an arrival airport: an airport has a unique identifier. Each flight has a pilot and a co-pilot, and it uses an aircraft of a certain type; a flight has also a departure time and an arrival time.
An airline owns a set of aircrafts of different types.
An aircraft can be in a working state or it can be under repair, and in a particular moment an aircraft can be landed or airborne.
A company has a set of pilots: each pilot has an experience level: 1 is minimum, 3 is maximum.
A type of aircraft may need a particular number of pilots, with a different role (Ex. captain, co-pilot, and navigator): there must be at least one captain and one co-pilot, and a captain must have a level 3.
