Final answer:
The question deals with the advisory services provided by FICs and FSS to ensure safety on maneuvering areas at uncontrolled aerodromes, including advisories on vehicle and pedestrian movement, weather conditions, and potential hazards like SAM sites and military aircraft activities.
Step-by-step explanation:
The subject of the question pertains to the operating procedures and safety measures in place concerning the movement of vehicles, equipment, and pedestrians on the maneuvering areas at designated uncontrolled aerodromes. This information and advisory service is provided by Flight Information Centres (FICs) and Flight Service Stations (FSS) to ensure the safety of all aerodrome users in the absence of air traffic control. The advisory services typically include information on other traffic such as aircraft and service vehicles, weather conditions, and potentially hazardous situations like a confirmed surface-to-air missile (SAM) site, a possible SAM site, or activities at an airfield with MIG aircraft.
