What is one of the rules regarding aerodrome traffic to avoid collisions?

Observing aerodrome traffic is fundamental for ensuring safety and preventing collisions in busy airspaces. This means that pilots and ground personnel must be vigilant in monitoring the movements of other aircraft and vehicles around the aerodrome. By doing so, they can anticipate potential conflicts and take appropriate actions, such as adjusting speed, altitude, or route, to maintain safe distances from other aircraft.

Being aware of surrounding traffic also involves good communication and coordination, particularly when taxiing on the ground or while preparing for takeoff and landing. This situational awareness is crucial in preventing accidents and ensuring a smooth flow of operations at the aerodrome, especially in environments where various aircraft and ground vehicles are in close proximity.

The other choices do not adequately align with safety practices concerning aerodrome traffic. For instance, flying at high altitudes may not be relevant in the context of ground operations where collisions with other aircraft or vehicles are a risk. Ignoring other aircraft is contrary to best safety practices, as this poses a significant risk of collision. Similarly, relying solely on visual communication without other means can lead to misunderstandings in busy airspace, making it vital to observe and communicate comprehensively.
