Some additional real world numbers for turbines is the average flight hours
per takeoff/landing.  Looking at the used turbine market, both turboprop and
jet(including Hawkers, Falcons, Gulfstreams, 737 bizjet, etc) shows that the
average ranges from 1.1 to 1.5 flight hours/takeoff-landing.  In reality, we
don't even come close to those long flights which we dream about.  While
some do make long commuting business flights, from my experience and
listening to other pilots most of us probably do average around 1 to 2 hours
of flight time per flight plan. Other considerations will therefore dictate
the choice of engines/fuel.
