Baker BeachNote that most destinations on the above map of San Francisco lie within just 1 mileof a potential pocket airport and virtually no point lies more than 3 miles from apotential pocket airport.Converting communities to pocket airports will in itself be powerfully Green. Eliminatingnearly 2 hours and 60 miles of surface travel to metro airports, often involving fuelwastinggridlock, could spare the need for more lanes on highways. It has been reportedthat in one year, Americans wasted 2.9 Billion gallons of gasoline while stuck ingridlock 13 , much of it in metro areas near large hub airports. The value of the time wastedin traffic is incalculable but enormous. Pocket airports could greatly reduce such waste.
30 High energy efficiency and emission-free or bio-fueled aircraft will reduce carbonemissions. Distributed air travel, i.e., flying ‘as the crow flies’, shaves about 10% off ofthe trip miles a car or mass transit would entail. 15 These aspects of Greenness areindependent of the actual MPG of the aircraft and might justify allowing SAVs to achieveless than the 200 pMPG demanded by GFC I.Pocket airports offer a redundancy for airborne disaster relief and a more distributedsystem for Med-evac air ambulance. They are an ideal fit with Peter Calthorpe’s 11 NewUrbanism and its “transit-oriented development”. The future of transportation is not moresingle file surface byways. It is not more cars or more lanes on the freeway.GREEN FIELD AIRPORTSAnother iteration of Green Aviation is the “Green Field Airport”, as conceived by GreenFlight Challenge Team PC-Aero’s Calin Gologan. This is a self-contained, small ruralairport that is capable of producing the energy necessary for its aircraft using solar panelson the roof of its hangars. Its main purpose would be as a site for flight training, sport andrecreational flying and as an access portal to remote areas. It could also serve as a relieverairport for the air traffic from pocket airports. An artist’s conception of such an airport isgiven below:
