• B. Entrances to a runway or areas where aircraft are not allowed to enter
• C. Locations of emergency exits on the runway

Answer: (B)

Mandatory instruction signs serve a crucial function in airport operations, as they clearly indicate entrances to runways or areas where aircraft are not permitted to enter. These signs are typically red with white lettering, making them easily recognizable for pilots and ground personnel. Their primary goal is to prevent incursions into restricted zones, enhancing safety and preventing accidents. By effectively conveying essential information about runway and area access, mandatory instruction signs help ensure that aircraft follow the correct paths during taxiing and landings. The visibility and clarity of these signs play an important role in maintaining orderly traffic flow on the airfield and ensuring compliance with airport regulations.
