For each of the following events, indicate whether the event would cause you to consider its effect on your current aircraft insurance policy and explain why:

• You have spent several thousand dollars to upgrade the aircraft's avionics.
• You are going to allow another pilot to fly your aircraft.
• You've been using the aircraft only for your own recreational, proficiency, and business travel, but have earned your flight instructor certificate and now want to also use the aircraft to start a flight instruction business.
• You've been flying your aircraft only within the contiguous ("lower 48") U.S. but are now planning to fly it on a trip to Alaska.
• You've paid off the loan you took out to purchase the aircraft.
