What happens if an aircraft deviates from its flight plan?

When an aircraft deviates from its flight plan, it's important for the pilot to maintain communication with air traffic control (ATC). Reporting their position allows ATC to understand the aircraft's current location and intentions. This information is crucial for maintaining safe separation from other flights and effectively managing air traffic in the area.

Maintaining situational awareness is key in aviation, and by providing position reports, pilots help ensure that both they and ATC can make informed decisions based on the current flight situation. This practice supports the overall safety and efficiency of air traffic management.
