[0002] With social progress and economic development, the civil aviation transport industry has flourished. In an airport, there may even be multiple aircraft on the runway at the same time within a short period of time. Airport taxiways are usually used for aircraft taxiing, taking off and landing. During the closure of an airport's runway, aircraft within the airport still need to use the taxiway to complete specific navigation tasks due to ground maintenance, emergencies or other factors. Traditionally, in order to ensure that aircraft safely cross the taxiway when the runway is closed, it is necessary to issue a corresponding navigation notice to remind the crew. However, the reminders in the text content of the navigation notice have limitations and are easily misunderstood or ignored by the crew. Summary of the invention
