The core of this library is to process position information from aircraft in order to determine basic information about the flight. The PositionUpdate object contains the position information we’re talking about here.

A PositionUpdate contains the following information:

• Latitude
• Longitude
• Altitude
• Speed
• Heading
• Timestamp

This information is the basis on which both the FlightContext and FlightContextFactory work to process flight information.

A PositionUpdate instance is immutable and can be initialized by using the constructor.

public PositionUpdate(string aircraft, DateTime timeStamp, double latitude, double longitude, double altitude, double speed, double heading)
