“That’s why you take the American Eagle flight in from Tyler.”
Yep, just like taking the American Eagle flight from Burbank instead of LAX.
Wait for FAA NEXTGEN it’s optimized for point to point airtaxi type flights from small regional or small general aviation airports. With STOL coming to market very small STOL strips become viable under 100 yards long and 30 feet wide, no need for thick concrete , grass works so does gravel or basic squirt top asphalt. The aircraft have less wheel loading than a car so really any road could be used that’s at least 100 yards straight and no trees or power lines over it.
MEXTGEN is electronic flight plan filing, VFR and IFR, it also does ADS-B out&in , TCAS traffic avoidance, MODE-S, and UAT it’s fully automated for aircraft separations, clearances and vectors.
Having a STOL or gyrodyne you would Efile a flight plan for takeoff from a field or helo LZ then when you get the electronic clearance takeoff and fly the vectors out of controlled airspace which in nearly every city extends to the ground for big portions of the area due to proximity to existing airports. Once outside of class B,C,D you are either in VFR and free to fly class E on your own or if it’s IMC then you are flying IFR on your already filed flight plan to your primary airport,STOL port or Helo LZ all of which would have instrument procedures to be your primary in IMC.
No need to deal with large airports when EVTOL(aka uberair) , STOL or gyrodynes are in the market.
