AIR TRAFFIC MANAGEMENT
FREE FLIGHT CONCEPT
PRESENTING BY: AMNA HAFEEZ
FREE FLIGHT CONCEPT
Free flight is a new concept being developed to take the place of the current air traffic management methods through the use of technology. True free flight eliminates the need for Air Traffic Control (ATC) operators by giving the responsibility to the pilot in command.
What is free flight?
Air Traffic Management conceptMore freedom in selecting rulesNo longer restricted to airwaysDirect route but airborne separationFree flight concept under IFR conditions
HISTORYFree flight began as an effort to become less dependent on the human factor and more dependent on the growing technology of its day.
Free flight were identified in 1971 by United Airlines systems manager William Cotton
In the 1970's the GPS satellite navigation system
In 1991 the International Civil Aviation Organization created the Future Air Navigation System Panel
In 1995 David Hinson plans to implement free flight

UNRESTRICTED
Little guidance from ATCFlexibility to fly for pilotsComplicated in bad weatherATC will have to assist the pilots and guide
RESTRICTEDThe freedom of the pilot has been restricted
significantly.TRANSITIONSlightly restricted however pilots retain some
flexibility to exercise free flight.

EXAMPLES
Free flight is operational in Alaska and Hawaii, and part of the Pacific Ocean
Using about 2,000 aircraftFull implementation is projected to take 20
years
NEXT GENERATION AIR TRANSPORTATION SYSTEM
The Next Generation Air Transportation System (Next Gen) proposes to transform air traffic control system from an aging ground-based system to a satellite-based system. GPS technology will be used to shorten routes, save time and fuel, reduce traffic delays, increase capacity.
QUESTIONS ARISES
What on-board equipment is needed to avoid traffic?
Will the pilots be able to cope with the extra task?
Is it safe? Will pilots feel safe? What happens in extremely busy traffic
situations?
CONCLUSION
In conclusion, many new technologies and operational concepts are being examined for the future air traffic control system. Making intelligent choices will depend on finding systems and concepts that allow both pilots and controllers to maintain situation awareness.
