You have been appointed a project manager within an information systems organization. Your job is to build an application that is quite similar to others your team has built and is quite familiar to the kind of requirements that need to be implemented and with the tools and technologies required for the development of such type of applications, although this one is larger and more complex. Requirements have been thoroughly explained and documented by the customer and agreed upon.

Design and draw UML class diagram with attributes, behavior, and class relationships for

the following scenario. Model a system for an airline management system that manages

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 as a unique identifier. Each flight

has a pilot and a co-pilot, and it uses an aircraft of a certain type. A flight also has 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. In a 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 several pilots, with a different role

(e.g.: captain, co-pilot, navigator).
