Jet aircraft are not fuel-efficient for short
trips
- jets consume about 12 gallons per passenger for a 300 mile trip when all seats are
filled, which is about 15 gallons per passenger at the typical 80% seat occupancy rate.
The fuel efficiency is thus about 20 passenger miles per
gallon for jets with 80% seat occupancy.
The fuel efficiency for 6 seat Skycar flying 300
mile trips with 60% occupancy
is calculated to be 42 passenger miles per gallon,
which is similar to fuel-efficiency of turboprops*.
