Final answer:
O/Cs are authorized to provide an instrument approach and limited traffic information at aerodromes within MF areas.
Step-by-step explanation:
The subject of this question is Aviation. An O/C (Obligation/Control) is authorized to provide an instrument approach.
O/Cs provide limited traffic information at aerodromes within MF (Mandatory Frequency) areas.
APRT RDO/CARS (Airport Radio/Canadian Aerodrome Reporting Service) are located at specific aerodromes within MF areas. O/Cs do not provide air traffic control services.
Pilots must communicate on the MF as per uncontrolled aerodrome procedures.
At aerodromes within controlled airspace served by APRT RDO/CARS, pilots must contact ATS (Air Traffic Services) via the RCO (Remote Communications Outlet), PAL (Pilot Activated Lighting), or telephone to obtain special VFR (Visual Flight Rules) authorization or IFR (Instrument Flight Rules) clearances.
