What is the primary difference between a flight plan and a flight itinerary?

The primary distinction between a flight plan and a flight itinerary lies in their intended purposes and the audiences they serve. A flight plan is a formal document filed with aviation authorities that outlines the details of an intended flight, including the route, altitude, and estimated times of departure and arrival. This is crucial for air traffic control and search and rescue operations, as it helps ensure safety and facilitates tracking of the flight within controlled airspace.

On the other hand, a flight itinerary is designed for passengers; it is typically issued by airlines or travel agents and provides an overview of the travel arrangements, including flight details, layover information, and reservation numbers. It serves as a guide for passengers to understand their travel schedule, but it does not hold the same official authority or safety controls as a flight plan.

Understanding this difference is essential for private pilots when preparing for flights, as it forms a key part of ensuring compliance with regulations and conducting safe operations in the airspace system.
