1.1.1 The general meteorological minima for visibility and distance from cloud for VFR flights are prescribed in CAR 91.301. These minima are summarised in Table 1.

1.1.2 The exceptions to the minima summarised in Table 1 are detailed in paragraphs 1.2, 1.3 and 1.4 ENR 1.2.1 below.

Table 1. Airspace VFR meteorological minima

	Class of Airspace	Distance from cloud	Flight visibility
	C and D	2km horizontally; 300m (1000ft) vertically outside a control zone; 150m (500ft) vertically within a control zone;	8km at or above 3000m (10000ft) AMSL;
G	Above 900m (3000ft) AMSL or 300m (1000ft) above terrain, whichever is the higher;	2km horizontally; 300m (1000ft) vertically;	5km below 3000m (10000ft) AMSL;
	At or below 900m (3000ft) AMSL or 300m (1000ft) above terrain, whichever is the higher;	Clear of clouds and in sight of the surface.	5km

1.1.3 Notwithstanding the meteorological minima detailed in Table 1, pilots performing air operations (an air transport operation or a commercial transport operation as defined in CAR-General terms and definitions) must comply with the meteorological conditions prescribed in CAR-121, CAR-125 or CAR-135 as appropriate.

1.2.1 Notwithstanding the VFR meteorological minima summarized in Table 1, a pilot of:

1. a helicopter may operate in Class G airspace with a visibility of less than 5km if operated at a speed that will give adequate opportunity to observe other traffic or any obstructions in order to avoid collisions;

2. an aircraft performing agricultural aircraft operations may operate in Class G airspace with a flight visibility of less than 5km but not less than 1500m; and

3. an aircraft performing flight instruction may operate within a low flying zone designated under CAR-71 with a flight visibility of less than 5km but not less than1500m.

1.3.1 Except for flight under Special VFR, a pilot is not permitted to take off or land an aircraft, or fly in the vicinity of an aerodrome under VFR when the flight visibility, or the cloud ceiling, is less than the minima summarised in Table 2 and 3:

Table 2. VFR MET minima at aerodromes within a control zone

		Ceiling	Visibility
All aircraft	Day and night	450m (1500ft)	5km

Table 3. VFR MET minima at aerodromes in uncontrolled airspace

		Ceiling	Visibility
All aircraft	Day	200m (600ft)	1500m

1.4.1 CAR-91.303 allows the pilot of an aircraft to perform a VFR operation within a control zone in weather conditions below those normally prescribed, provided that the operation is performed:

1. in compliance with an ATC clearance and ATC instructions;

2. by day only;

3. clear of clouds;

4. with the ceiling and visibility detailed in Table 4, except that helicopters may operate with lower minima, if the helicopter is operated at a speed thatwill give adequate opportunity to observe other traffic or any obstructions in order to avoid collisions; and

5. in an aircraft equipped with two-way radio capable of communicating with ATC on the appropriate frequency.

Table 4. Special VFR meteorological minima.

		Ceiling	Visibility
All aircraft	Day	200m (600ft)	1500m

1.4.2 Requests for authorisation to enter or transit a control zone as a Special VFR flight may be made by radio or telephone. Authorisation to operate as a Special VFR flight does not absolve the pilot from compliance with CAR-91.311 regarding minimum heights for VFR flight.
