List your primary destinations and the distance to each, how many people you will routinely carry, typical weight of passengers and luggage carried, if any destinations will be high altitude airports, if you anticipate flying over mountainous terrain, need an IFR certified or pressurized aircraft, will require de-ice capability, or will carry any passengers with mobility issues.
Are hangars available that will accommodate the size of aircraft you are considering? What is the length of the longest runway? Are instrument approaches available? Please elaborate.
Which ones peak your interest? Why? Have you received specific aircraft recommendations from others?
Feel free to clarify any of your previous responses here.
