Final answer:
A certified or registered aerodrome defines an aerodrome with a Canadian aviation document in force, ensuring compliance with Transport Canada's safety standards.
Step-by-step explanation:
The term that defines an aerodrome in respect of which a Canadian aviation document, issued pursuant to the Aeronautics Act, is in force is known as a ‘certified aerodrome’ or ‘registered aerodrome’. This term refers to aerodromes that have met the regulatory requirements established by Transport Canada and have been granted a certificate under the Canadian Aviation Regulations (CARs). It is important for an aerodrome to be certified as it ensures it complies with safety standards for airport operations. Options such as ‘Apron’, ‘Airside Area’, ‘Air Traffic Control (ATC)’, and ‘Controlled Taxiway’ do not correspond to the definition of an aerodrome with a Canadian aviation document in force. These terms refer to specific areas or services within an aerodrome’s operations.
