A Very Light Jet (VLJ) is a small jet aircraft approved for single-pilot operation. With a maximum take-off weight of under 10,000 lb (4,540 kg), they are lighter than corporate aircraft and seat between three and six passengers.
A number of designs are currently in development, and will feature advanced avionics with glass cockpit technology. VLJs are intended to have lower operating costs than conventional jets, and will be able to operate from runways as short as 3,000 feet (900 m). NASA and the FAA encourage the development of these light jets and foresee their widespread use in point-to-point air taxi service. This Small Aircraft Transportation System would provide air service to areas ignored by airlines.
Eclipse Aviation expects its E500s to be used as air taxis or flying limosines for corporate travelers.
