for this kind of aircraft. Hot temperature, full load = long take off roll. A twin Otter (twin engine turboprop) would be more appropriate for this kind of operation but is way more expensive to buy and run(more fuel etc, maintenance). Fortunately engine failures are a fairly rare occurrence but they can happen. You just hope with a single engine a/c that u have warning of an impending engine failure in the early part of the takeoff roll! If the pilot complied with the operating manual, maybe half the passengers would be left behind!
