Which taxiways can be crossed in normal weather conditions?

The correct choice emphasizes the allowance to cross specific uncontrolled taxiways during normal weather conditions, which include taxiways Q and C. Uncontrolled taxiways typically have less stringent operational restrictions than controlled ones and are generally marked for access in a standard traffic situation. This means that trained operators can navigate these taxiways more freely without the need for explicit air traffic control guidance, provided they follow standard procedures and ensure safety.

Controlled taxiways, by contrast, require coordinated communication with air traffic control. This increases the complexity and might restrict crossings unless specifically authorized. By designating multiple uncontrolled taxiways available for crossing, the choice reflects a practical understanding of where operators can safely maneuver while minimizing unnecessary delays or interactions with control.

It is important to adhere to the regulations set forth by airport operators regarding which taxiways are permissible for crossing, especially in varying weather conditions to ensure safety and compliance with airside operations.
