It's clearly marketed for remote communities with little to no connecting infrastructure. Think Alaskan wilderness or Hawaiian island hopping. This isn't for getting from LA to Denver for skiing.
More likely, this replaces the turboprop or commuter jet from Colorado Springs to Denver to catch the connecting fright to any other major airport.
A piston or turbine powered aircraft can run all day.
Odd added benefit: the potential ability to jettison a huge part of the weight in extreme emergencies to increase flying time by the backup ICE system.
