i) the ceiling shall not be less than 450 m (1 500 ft);
ii) except as specified in (c)(4), the reduced flight visibility provisions specified in Table S5-1(a) and (b) shall not apply;
iii) in airspace classes B, C, D, E, F and G, at and below 900 m (3 000 ft) above MSL or 300 m (1 000 ft) above terrain, whichever is the higher, the pilot shall maintain continuous sight of the surface;
iv) for helicopters in airspace classes F and G, flight visibility shall not be less than 3 km, provided that the pilot maintains continuous sight of the surface and if manoeuvred at a speed that will give adequate opportunity to observe other traffic or obstacles in time to avoid collision; and
v) for mountainous terrain, higher VMC visibility and distance from cloud minima may be prescribed.

i) over high terrain or in mountainous areas, at a level which is at least 600 m (2 000 ft) above the highest obstacle located within 8 km of the estimated position of the aircraft;ii) elsewhere than as specified in (i), at a level which is at least 300 m (1 000 ft) above the highest obstacle located within 8 km of the estimated position of the aircraft.”

“f) Except when necessary for take-off or landing, or except by permission from the competent authority, a VFR flight shall not be flown:

1) over the congested areas of cities, towns or settlements or over an open-air assembly of persons at a height less than 300 m (1 000 ft) above the highest obstacle within a radius of 600 m from the aircraft;

2) elsewhere than as specified in (1), at a height less than 150 m (500 ft) above the ground or water, or 150 m (500 ft) above the highest obstacle within a radius of 150 m (500 ft) from the aircraft.”

i) ATC route clearances;
ii) clearances and instructions to enter, land on, take off from, hold short of, cross, taxi and backtrack on any runway; and
iii) runway-in-use, altimeter settings, SSR codes, newly assigned communication channels, level instructions, heading and speed instructions; and
iv) transition levels, whether issued by the controller or contained in ATIS broadcasts.

a) such flights may be conducted during day only, unless otherwise permitted by the competent authority;
b) by the pilot:
1) clear of cloud and with the surface in sight;
2) the flight visibility is not less than 1 500 m or, for helicopters, not less than 800 m;
3) at speed of 140 kts IAS or less to give adequate opportunity to observe other traffic and any obstacles in time to avoid a collision; and
c) an air traffic control unit shall not issue a Special VFR clearance to aircraft to take off or land at an aerodrome within a control zone, or enter the aerodrome traffic zone or aerodrome traffic circuit when the reported meteorological conditions at that aerodrome are below the following minima:
1) the ground visibility is not less than 1 500 m or, for helicopters, not less than 800 m;
2) the ceiling is not less than 180 m (600 ft).
