What drives the real price?
Airframe and engine time, maintenance history, damage history, avionics, equipment, geography and tax treatment can move a real transaction well outside a model-level estimate. A cheaper example with deferred maintenance can be the more expensive aircraft after the first annual inspection.
What is included?
PlaneFit combines an annual fixed-cost base with a direct hourly estimate. The result is intended for comparing aircraft and testing utilisation scenarios. It is not a maintenance programme quote, insurance quote or pre-buy assessment.
The DHC-6 Series 300 Twin Otter combines 12-seat turboprop capability with about 527 NM reported range and about 175 kt reported cruise, while payload, runway and operating-cost figures remain indicative and should be verified for the specific aircraft before making a decision.
