Hej Leif
Luftrummet er lettere at geare til store mængder skycar, end biltrafikken.
Det er der mange grunde til:
1) Vejnettet kan ikke håndtere bil myldretidstrafikken uden forsinkelse.
Det gælder i mange storbyer. Skycaren har 3D korridor-net tilrådighed i
op til ca. 10 km højde og har også brug for lette-korridor og
lande-korridor.
2) Der er ikke nok parkeringspladser. Det gælder også i mange storbyer.
Skycaren kan med fordel udgøre et globalt offentligt transportnet.
3) Det er lettere at automatisere lufttrafik end biltrafik, fordi det
faktisk er ret vanskeligt at navigere på veje - især i byområder. Der er
for mange forhindringer på landjorden. I luften er der kun fugle og hvis
radarsystemet ikke kan undgå fugl(ene) vil gitter som af
sikkerhedsmæssigt årsager er for nacelle indsugningen forhindre fugle og
mennesker i at komme i nærkontakt med de 4 propeller i nacellerne.
4) Lufttrafik behøver ikke snerydning og oplever ikke akvaplaning.
Skycar kan dog ikke klare orkanvejr og overisende vejr.
Flere argumenter er her:
Overview of Skycar
http://www.skyaid.org/Skycar/over1T.htm
Citat: "...
The satellite-based Global Positioning System with emergency
ground-based radio navigation will provide instant, accurate
navigation. An obstacle-avoidance radar looking forward and down can be
added for safety.

Comparison of Aircraft
...
The Skycar will be even safer when full electronic piloting is added.
When added, pilots will not be required to make split-second decisions
in difficult situations. The combination of electronic pilot backed up
by a ground controller will virtually eliminate errors made under
conditions of fatigue, drunkenness, poor visibility, or distraction.
In the highly unlikely event that several engines fail, two ballistic
parachutes on the airframe will prevent a fatal crash. The Skycar's
aerodynamic body provides a 9 to 1 glide slope for making an emergency
landing at an airport or open area with parachutes.
If a parachute landing is needed over water the Skycar will float,
enabling passengers to debark with life preservers. The proposed design
should be able to land and take off from water.
The Skycar will also be safer than an automobile because it is not
limited to a single dimension for maneuvering. It has no road edges,
guard rails or slippery roads to avoid, no dangerous traffic congestion,
and no mechanical failure or human error to contend with.
With the electronic pilot, the Skycar accident rate should be lower than
for other aircraft. The Skycar will react quickly, have more
maneuverability, will follow safe electronic flight rules, will have
radar observability for at least 5 miles ahead, and will have
communication with other vehicles as well as with the ground controller.

Der er selvfølgelig behov for et Skycar flyvning planlægningssystem. I
USA bliver der arbejdet på et, som kan anvendes til f.eks. et
Skycar-transportsystem.

Skycar har 8 motorer, hvoraf 2 kan gå istå i hver sin nacelle og det kan
den flyve videre med. Så den er ret sikker.
