Final answer:
Class F airspace designated as CYA with a (P) suffix is 'Controlled VFR airspace,' while a (M) suffix indicates a 'Controlled IFR airspace' where communication on a specified frequency is mandatory.
Step-by-step explanation:
If it is a Class F airspace and is said to be: CYA 113(P) or CYA 125(M), we need to understand what those designations mean to determine its controlled status. The "CYA" generally stands for "Advisory Area" and is unique to Canada's aviation system.
In Canada, Class F airspace may be designated as CYA followed by a number, with an additional suffix that describes its use. The suffixes are as follows: (P) for Prohibited, (R) for Restricted, (D) for Danger, (M) for Mandatory Frequency Area, and (A) for Advisory. A "Prohibited" airspace (P) is a form of controlled airspace where no aircraft are allowed without special permission, whereas a "Mandatory Frequency Area" (M) is an area where it is mandatory to communicate on a specified frequency for air traffic services.
Given these definitions:
- Class F airspace with a (P) designation would be considered controlled VFR airspace.
- Class F airspace with a (M) designation, while requiring communication, does not necessarily imply that it is controlled airspace. But it is specific in that pilots are required to use a specific frequency for air traffic services and is thus a form of controlled IFR airspace when operating under IFR (Instrument Flight Rules).
In conclusion, the answer to the student's question would be a) Controlled VFR airspace for CYA 113(P) and c) Controlled IFR airspace for CYA 125(M).
