Before entering a runway, which action should be taken?

• A. Contact Control Tower Or Other Airfield Control Authority To Gain Clearance
• B. Obtain A Runway Entry Permit
• C. Check Weather Conditions
• D. Ensure You Have A Ground Guide

Answer: (A)

Entering a runway requires explicit authorization from air traffic control. The control tower coordinates all movements on the airfield surface to prevent conflicts between aircraft and vehicles, especially as aircraft accelerate for takeoff or decelerate after landing. By contacting the control tower or the appropriate airfield control authority, you obtain the official clearance that confirms the runway is active for your movement, provides any taxi instructions, and ensures you’re aware of other traffic.

Checking weather conditions is important for safety, but it does not authorize entry onto a runway. A runway entry permit is not a standard credential used to grant access. Having a ground guide can assist with taxiing in some situations, but it does not replace the requirement for ATC clearance before entering a runway.
