When nearing a military airfield, what action should pilots take regarding their flight plans?

When approaching a military airfield, it is crucial for pilots to modify their flight plans to avoid military operations. This action is necessary to ensure safety and compliance with military airspace management procedures. Military operations may include training missions, exercises, or other activities that could pose risks to civilian aircraft if they enter the airspace without coordination.

By modifying the flight plan, pilots can avoid potential conflicts, adhere to any specific instructions issued by air traffic control, and ensure they do not inadvertently interfere with military operations. This responsiveness not only reflects good airmanship but also demonstrates a commitment to safety and operational protocol in shared airspace.

Maintaining the existing flight plan or proceeding without changes may lead to safety hazards if the flight inadvertently enters an area of active military operations. Turning off all communication equipment would eliminate vital contact with air traffic control, further increasing the risk of miscommunication and operational conflicts. Therefore, modifying the flight plan is the optimal response to ensure safe and coordinated operation near military airfields.
