AMC1 NCO.OP.110 Aerodrome
operating minima — aeroplanes and helicopters
TAKE-OFF OPERATIONS
(a) General
Take-off minima should be expressed as visibility (VIS) or runway visual range (RVR) limits, taking into account all relevant factors for each runway/final approach and take-off area (FATO)/operating site planned to be used and aircraft characteristics and equipment. Where there is a specific need to see and avoid obstacles on departure and/or for a forced landing, additional conditions, e.g. ceiling, it should be specified.
(b) Visual reference
(1) The take-off minima should be selected to ensure sufficient guidance to control the aircraft in the event of both a rejected take-off in adverse circumstances and an engine failure after rotation.
(2) For night operations, sufficient lighting should be in operation to illuminate the runway/final approach and take-off area (FATO) and any relevant obstacles.
(3) For point-in-space (PinS) departures to an initial departure fix (IDF), the take-off minima should be selected to ensure sufficient guidance to see and avoid obstacles and return to the heliport if the flight cannot be continued visually to the IDF. The minimum VIS should be 800 m and the minimum ceiling should be 250 ft.
(4) For helicopters outside of a runway environment, the minimum VIS should be 800 m, and for offshore helideck operations, the minimum VIS should be 500 m.
Aeroplane and helicopter takeoff requires visibility or runway visual range limits, considering runway, aircraft, and equipment. Obstacle avoidance and forced landing scenarios must be accounted for. Night operations need sufficient lighting. Point-in-space departures require specific visibility and ceiling minimums for obstacle avoidance and return. Helicopter operations outside runways have visibility minimums.
