Final answer:
The requirement for an SFOC under CAR 903.01 is not solely based on flight visibility conditions such as Day VFR, Night VFR, or IFR but on the nature of the operation being conducted. It is important to assess the specifics of the proposed operation to determine if an SFOC is required.
Step-by-step explanation:
The types of flight conditions requiring a Special Flight Operations Certificate (SFOC) under Canadian Aviation Regulations (CAR) Section 903.01 are specific to the type of aerial work being conducted. The CAR 903 doesn't necessarily differentiate between types of VFR or IFR for the requirement of an SFOC; rather, it is the nature of the operation that will determine the requirement. Generally, an SFOC is required for activities that are outside the norm of standard flight operations, such as aerial fire-fighting, banner towing, or aerobatic performances, among others.
Day VFR (Visual Flight Rules) and Night VFR conditions are typically standard flight operation conditions, and an SFOC would not be defined solely by these conditions but instead by the specifics of the operation in question. For some operations, an SFOC may be required regardless of whether it is day or night. Meanwhile, IFR (Instrument Flight Rules) operations tend to pertain to the ability to fly in conditions where visual cues are limited or unavailable, and an SFOC would apply to specific operations rather than to IFR conditions universally.
To determine if an SFOC is needed, you must look at the specific operation being proposed and see if it falls under the types of operations enumerated by the regulations that require an SFOC, not just the flight rules in use at the time.
