Flight planning is the process of preparing for a flight by determining the best route, altitude, and fuel needs. Pilots consider various factors such as weather conditions, air traffic, and the aircraft's performance. This careful planning helps ensure a safe and efficient journey from the departure airport to the destination. During flight planning, pilots also create a flight plan, which is a detailed document that outlines the intended route and any alternate airports. This plan is filed with air traffic control, allowing them to monitor the flight and provide assistance if needed. Proper flight planning is essential for both safety and compliance with aviation regulations.
