What should be monitored during taxi to ensure safety?

Monitoring wingtip clearance during taxi is crucial for ensuring safety because it helps prevent potential collisions with nearby structures, other aircraft, or ground vehicles. As the aircraft moves on the ground, maintaining a safe distance from obstacles such as buildings, terminal gates, or other parked aircraft is essential. This vigilance is especially important in taxi environments, which can often be crowded and busy with various activities.

While visibility in the cockpit is vital for understanding the environment and situational awareness, it does not specifically relate to the aircraft's spatial movement and immediate clearance. Fuel levels and air pressure in tires are important for overall safety and operational readiness, but they are typically monitored more reliably during pre-flight checks and not specifically during taxiing. The focus during taxi is primarily on maneuvering the aircraft safely and maintaining the necessary clearance margins, making wingtip clearance a key aspect of taxi safety.
