Continued….Acceptable in flight wing aerodynamics while able to
retract , fold or detached and stow the wing for road travel.
Need to rotate on take off.To find engine/transmission which could meet the
conflicting demand of ground and air.Dual mode control systems.Stability and performance requirements in both modes of
travel.

Design conceptsGlenn Curtiss in 1917 exhibited his design of flying
automobile in Pan- American Aeronautic exposition in New York.
Waldo waterman was the first person to be granted a patent on roadable aircraft “Arrowbile” in 1937.

Conclusion The flying car concepts will require some more time to
be in reality.
Roadable aircrafts design and development are feasible.
Cost of roadable aircrafts play a vital role in their success.
The success of roadable aircrafts will end uncertain
weather, rising costs, and ground transportation hassles on
each end of the flight.
