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 concept
More freedom in selecting rules
No longer restricted to airways
Direct route but airborne separation
Free flight concept under IFR conditions
Free 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
In 1991 the International Civil Aviation
Organization created the Future Air Navigation
In 1995 David Hinson plans to implement free
HUMAN FACTORS OF FREE
Free flight would represent more
Little guidance from ATC
Flexibility to fly for pilots
Complicated in bad weather
ATC will have to assist the pilots and guide
The freedom of the pilot has been restricted
Slightly restricted however pilots retain some
flexibility to exercise free flight.
APPROACHES OF FREE FLIGHT
Free flight is operational in Alaska and
Hawaii, and part of the Pacific Ocean
Using about 2,000 aircraft
Full implementation is projected to take 20
NEXT GENERATION AIR
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
What on-board equipment is needed to avoid
Will the pilots be able to cope with the extra
Is it safe? Will pilots feel safe?
What happens in extremely busy traffic
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.
