Navigation Rules: For a flawless flight

The navigation rules help determine the best route for a flight, taking into account various airspace constraints, such as restricted areas, altitude restrictions, or necessary course changes to avoid obstacles.

They are used to plot an accurate route on an aviation chart, whether it’s for visual flight rules (VFR) or instrument flight rules (IFR). This helps to establish a clear path to follow, with a precise heading, and to calculate the distances between various waypoints. For more information, please consult our article on how to prepare for a VFR navigation.

They are equipped with markers, scales, and reports, which allow pilots to easily measure the distance between two points on a chart. Additionally, they are used to measure heading angles, particularly when it’s necessary to know the angle at which an aircraft must fly to reach a specific destination. This ability to accurately measure distances and angles is crucial to ensure the flight follows the correct route, especially under variable weather conditions.

They are also used to estimate the average speed of a flight and to calculate the time needed to cover a given distance, based on the aircraft’s speed. This allows pilots to plan their flight more precisely, accounting for necessary stops, fuel consumption, and external factors like winds.

In flight, they are also useful for adjusting the aircraft’s trajectory in real-time. If a pilot needs to make a deviation due to unforeseen weather conditions or changes in airspace, they can use the rule to quickly recalculate the new route to follow. This helps maintain safety margins while optimizing the route according to the circumstances.

BAYO offers a wide range of tools and accessories for pilots. Among the flagship products, there are essential navigation rules for flight planning and execution, such as the IFR Route Rule PV-5, designed for instrument flight conditions (IFR). It allows pilots to trace precise routes using suitable scales. It is particularly useful for pilots flying in controlled airspace.

Also available is the SIA Route Rule which is tailored to the needs of pilots flying in France. It simplifies route plotting using the aeronautical charts from the Aeronautical Information Service (SIA).

Other products are also available, such as the navigation rule 1: 500,000 and 1: 1,000,000, the PJ1 Route Rule with Protractor... Also, check out our flight logs which allow you to record all your flights.

In short, navigation rules allow pilots to plan their routes, measure distances and angles, and adjust their trajectory in real-time. These tools ensure safety and competence, offering pilots reliable navigation, whether they are flying visually or by instruments. Mastering these rules means flying with confidence and peace of mind!
