VFR flights between sunset and sunrise, or such other period between sunset and sunrise as may be prescribed by the appropriate ATS authority, shall be operated in accordance with the conditions prescribed by such authority. VFR Flight RulesĮxcept when operating as a special VFR flight, VFR flights shall be conducted so that the aircraft is flown in conditions of visibility and distance from clouds equal to or greater than those specified in the table above.Įxcept when a clearance is obtained from an air traffic control unit, VFR flights shall not takeoff or land at an aerodrome within a control zone, or enter the aerodrome traffic zone or traffic pattern:Ī) when the ceiling is less than 450 m (1500 ft) orī) when the ground visibility is less than 5 km. in areas of low volume traffic and for aerial work at low levels.ī) Helicopters may be permitted to operate in less than 1500 m flight visibility, if manoeuvred at speeds that will give adequate opportunity to observe other traffic or any obstacles in time to avoid collision. ** When so prescribed by the appropriate ATS authority:Ī) flight visibilities reduced to not less than 1500 m may be permitted for flights operating:ġ) at speeds that, in the prevailing visibility, will give adequate opportunity to observe other traffic or any obstacles in time to avoid collision orĢ) in circumstances in which the probability of encounters with other traffic would normally be low, e.g. * The VMC minima in Class A airspace are included for guidance to pilots and do not imply acceptance of VFR flights in Class A airspace.
