What is the purpose of larger grid maps in aircraft operations?

Larger grid maps play a critical role in aircraft operations, particularly in identifying incident locations. These maps provide detailed spatial information about the airport layout, including runways, taxiways, terminals, and other relevant facilities. When an incident occurs, being able to effectively pinpoint the exact location is crucial for coordinating a rapid response by rescue and firefighting teams. Utilizing grid maps helps ensure that these teams can reach the incident site quickly and effectively, potentially saving lives and minimizing damages.

The other options focus on aspects that, while important in the broader context of airport operations, do not directly pertain to the specific function of larger grid maps. Emergency contact information and passenger boarding procedures relate more to operational communications and logistics. Aircraft scheduling is also an operational concern, but it does not involve the need for detailed spatial awareness provided by grid maps.
