IFR Departure
Part of the Ops Spec Exemption states that you are able to depart an aerodrome where the visiblity is below the landing minima, but ABOVE the take-off minima, provided that you have a takeoff alternate.
So as stated above, you must meet either A.) The climb gradient at 1/2 vis or B.) Spec Vis at 1-1/2 miles. Hope this helps
Cars Reference:
723.30 Take-Off Minima
(1) Weather Below Landing Limits
The standard for authorization to conduct a take-off in IMC when weather conditions are above take-off, but below landing minima for the runway in use are:
(a) the helicopter is multi-engine;
(b) an alternate aerodrome is specified in the IFR flight plan; and
(c) that aerodrome is located within the distance which can be flown in 60 minutes at the normal cruising speed.
