What do you need to do before you can monitor your progress with a GPS flight plan?

In order to effectively monitor your progress with a GPS flight plan, activating the flight plan is essential. Activating the plan ensures that the GPS system is aware of your intended route and that it can provide real-time navigation support as you fly. This step establishes the framework wherein all subsequent navigation data, including position updates and waypoint tracking, is generated and displayed on your GPS unit.

Without activation, the GPS may not provide accurate or relevant information concerning your flight path, making it difficult to effectively monitor your progress. Therefore, activating the flight plan is a crucial first step in ensuring that the system can provide the necessary updates and guidance throughout the flight. This step allows the pilot to receive critical alerts or deviations from the planned route, enhancing situational awareness and safety.
