What ground frequency should you use to determine position on the surface?

To determine the position on the surface, using the chart to identify the appropriate ground frequency is essential. Airport diagrams and charts provide accurate and relevant information informing pilots of the specific ground control frequencies they need to use for effective communication when taxiing and moving around the airport.

Consulting the chart ensures that pilots are referencing the most current and applicable information for that specific airport, which can vary between locations. Different airports might have distinct frequencies, and the chart will specify these details according to the operational requirements.

Using information from the flight plan or solely based on the aircraft type does not guarantee accurate positioning because frequencies may differ from one airport to another, and a flight plan might not include up-to-date or correct frequency information. Additionally, having a uniform approach across all airports does not apply since each location can have varying operational needs and protocols, necessitating the use of charts for proper guidance.
