Final answer:
Flight Information Regions (FIRs) identify which country controls the airspace and determine which procedures are to be used.
Step-by-step explanation:
A. True
Flight Information Regions (FIRs) are designated regions of airspace in which a specific country or authority provides air traffic services. These regions are established based on geographical and administrative boundaries. FIRs help in organizing and controlling airspace, facilitating the management of air traffic, and ensuring safety and efficiency in aviation operations.
Each FIR is managed and controlled by the responsible country or authority, which dictates the rules, regulations, and procedures to be followed within that specific airspace. Aircraft flying through FIRs are subject to the rules and procedures set by the controlling authority of that FIR. Therefore, FIRs play a crucial role in identifying the country that controls the airspace and determining the procedures to be used within those regions, making the statement true.
