What is the primary factor for Flight Planning during Visual Navigation sorties?

The primary factor for Flight Planning during Visual Navigation sorties is weather conditions. When navigating visually, pilots must have a clear understanding of the current and forecasted weather, as it significantly affects visibility, flight safety, and route selection. Adverse weather can obscure landmarks or create challenging flying conditions, necessitating careful planning to ensure safe and efficient navigation.

Relying on weather data allows pilots to plan routes that avoid storms, turbulence, and low visibility areas, making it crucial in visual navigation where pilots depend on sight rather than instruments. While airspeed, routing, and fuel management are important considerations in flight planning, they are secondary to the immediate effects that weather has on visual navigation capabilities. The pilot's ability to make informed decisions based on weather forecasts enhances safety and effectiveness during the flight.
