First, free flight can be defined as "the concept of safe and efficient flight operation in IFR where pilots can freely choose their own course and speed" (Wells and Young, p. 168). On a free flight, the control of the air traffic control center is canceled and the pilot can decide which pass and speed is best for the flight. The development of this process includes the transition from air traffic control to air traffic control.
The first one is a free flight to the threshold. The second is ATSP control arrival. Free flights to thresholds require that the cockpit be responsible for route planning and departments arriving from the aircraft. The plane is flying freely at the center. It is responsible for releasing it from other traffic. Traffic flow control restrictions to the terminal area are available to the crew. The crewmemor sequentially corrected the terminal arrival plan
When the traffic volume is very small, it may be different. In this case, the free flight area can approach the airport as much as the meter. Arrival settings from the aircraft to the center, they call it "free piloting mode". The flight crew is in charge of that department and the scheduled traffic control restrictions are then transferred from the planner. This is done by using CTAS 's Traffic Management Consultant to determine the flight level, while the crew is expected to prepare a flight route to land at the closest possible time.
For flights that are over reserved, airlines usually ask you not to fly to volunteers. In addition to hotel accommodation and future flight accommodation, they can compensate using free flight coupons or actual cash. Normally you need to raise a fee from the first offer so that these volunteers will be displayed (for example, $ 200 to $ 400, or $ 1,000). In the absence of volunteers, airlines frequently choose passengers at random, ask them not to board an airplane and provide them with a level of compensation for their contract or applicable law. In this case, the ticket agreement is written to have the right to deny the airline company to provide services to passengers.
