Final answer:
Juliet needs to review her insurance policy or consult her insurance provider to determine if business use of her airplane is covered, as standard policies typically only cover recreational use. She may need additional coverage for business trips.
Step-by-step explanation:
If Juliet has an insurance policy covering her airplane for pleasure flying, and she begins to use the aircraft for business trips, she may not be covered unless her insurance policy explicitly includes coverage for business use. Insurance policies often have specific exclusions and conditions that define what purposes or uses are covered. Therefore, to ascertain whether business trips are covered, Juliet should review her policy thoroughly or contact her insurance provider to confirm. If her current policy does not cover business trips, she may need to modify her policy or obtain additional coverage for business use to ensure she is fully protected during those flights.
