Why is it important for pilots to monitor taxi operations?

Monitoring taxi operations is essential for pilots primarily to avoid collisions on the ground. During taxiing, aircraft operate in close proximity to other planes, vehicles, and personnel on the runway and taxiways. Pilots need to be vigilant to ensure safe maneuvering, as the risk of accidents increases in these congested areas. By being aware of their surroundings and the movements of other aircraft, pilots can make informed decisions that enhance safety and prevent incidents.

The other options do not relate to taxi operations specifically. For instance, ensuring proper takeoff speed and maintaining altitude pertain more to the phases of takeoff and flight rather than taxiing. Calculating fuel usage is an important aspect of flight planning and operational efficiency but is not directly influenced by taxi monitoring. Thus, the focus on avoiding ground collisions underscores the critical safety responsibilities of pilots during taxi operations.
