Flight Management System Exercise DescriptionObjective: Design a class diagram for a flight management system that includes the following classes and relationships. Ensure that the diagram showcases aggregation, inheritance, and association.Classes: $1.$ AircraftProperties: model, capacity, airlineMethods: scheduleFlight$(),$ cancelFlight$()2.$ CommercialAircraft $($inherits from Aircraft$)$Properties: serviceClassTypes $($e$.$g$.,$ Economy, Business$)$ Methods: offerInFlightEntertainment$()3.$ CargoAircraft $($inherits from Aircraft$)$Properties: cargoCapacityMethods: loadCargo$(),$ unloadCargo$()4.$ FlightProperties: flightNumber, destination, origin, departureTimeMethods: delayFlight$(),$ advanceFlight$()5.$ CrewMemberProperties: name, role $($e$.$g$.,$ Pilot, Flight Attendant$)$ Methods: assignFlight$($Flight$),$ report$()6.$ PassengerProperties: name, age, ticketNumber Methods: checkIn$(),$ boardFlight$()$AirportProperties: name, locationMethods: listFlights $(),$ announce $()$FlightScheduleProperties: date, flights $($list of Flights$)$Methods: addFlight $($Flight$),$ removeFlight $($Flight$)$Relationships:Inheritance:CommercialAircraft and CargoAircraft inherit from Aircraft.Aggregation:FlightSchedule aggregates Flight.Airport aggregates Flight.Association:Flight is associated with Aircraft $($a flight uses a specific aircraft$).$CrewMember is associated with Flight $($crew members are assigned to flights$).$Passenger is associated with Flight $($passengers are booked on flights$).$Task:Create a class diagram using a UML tool or drawing software that includes the following:Show the inheritance between Aircraft and its subclasses.Illustrate the aggregation relationships involving Flightschedule and Airport.Detail the associations between Flight, CrewMember, Passenger, and other relevant classes.
