During RVOP operations, which signs are activated by ASOs and Wildlife?

The correct answer is related to the activation of specific signs by Airport Safety Officers (ASOs) and Wildlife Management during Runway Visual Observation Procedures (RVOP). Critical Area Signs are designed to indicate areas that are crucial for the safety and management of aircraft operations, especially where wildlife may pose a hazard.

In the context of RVOP, when wildlife is present on the runway or surrounding areas, ASOs have the responsibility to activate Critical Area Signs to alert ground personnel and pilots of potential dangers. These signs serve as critical alerts that help manage risk and enhance safety by ensuring that all personnel are aware of wildlife activity that could interfere with flight operations.

The other types of signs mentioned—such as Closed Area Signs, Runway Boundary Signs, and Taxiway Information Signs—serve different purposes relating to airport operations but are not specifically activated by wildlife presence through actions of ASOs in the context described. Thus, the emphasis on Critical Area Signs in this scenario is crucial for maintaining safety and operational efficiency on the airside of the airport.
