What type of information should be included in the data box for the Primary Navigation stage?

In the Primary Navigation stage, the data box should include essential navigational information that directly aids the pilot in maintaining the intended course to their destination. The inclusion of magnetic course is critical as it provides the pilot with the direction they need to fly, measured in degrees relative to magnetic North. This is fundamental for ensuring accurate navigation, especially when making adjustments due to wind drift or when executing turns.

While fuel burn rate, aircraft weight, and flight altitude are important parameters in the overall management of the flight, they do not play a central role in the navigation task at this specific stage. Fuel burn rate pertains primarily to operational efficiency and fuel management, while aircraft weight affects performance and efficiency but is not necessary for establishing course direction. Flight altitude is also vital for safe operation but serves a different purpose in navigation, focusing on vertical separation rather than lateral course tracking. Thus, magnetic course remains the most relevant piece of information for effective primary navigation.
