Helicopter IFR Takeoff Minimums[PDF]
IFR Take-off minima calculation for helicopters depends on several factors and is usually overlooked by pilots.
Aerodrome/Heliport Operationg Minima
Depending whether you are taking of from an aerodrome or heliport, pilots have to comply with the specified Aerodrome operating minima or heliport operating minima.
Some national regulations require helicopters to operate above a specified minimum.
Some aerodrome/heliport operating minimas or departure procedures require helicopters to achieve specific climb performance in VMC conditions. Some national regulations also require helicopters to gain Vmini before entering IMC conditions.
Approach Minima Of Departure Aerodrome/Heliport
The approach minima of a departure aerodrome/heliport give the answer to the question "Can I turn back to and land at my departure aerodrome/heliport if something happens after take-off which requires an immediate landing?"
If there is no take-off alternate and landing minima at the departure aerodrome/heliport is below take-off minima, the current ceiling and visibility of the departure aerodrome/heliport should be higher than the landing minima.
Take-off Alternate Aerodrome
The answer to the question "Where to land after take-off if something happens which requires an immediate landing and departure aerodrome/heliport ceiling and visibility is below the approach minima?" is the take-off alternate.
When the ceiling and visibility of the departure aerodrome/heliport is below the approach minima, a take-off alternate should be selected.
