Since it's an 'enroute' ifr you cannot do ifr take offs or approaches.
True, but VMC for
helicopters (in austria) in
airspace G means
- less than 1500m flight visibility when speed is low enough to avoid collisions.
Therefore helicopters in airspace G might be in a type of VMC whose parameters render it IMC for airplanes. E.g. only helicopters among themselves.
So for helicopters in 'G' the enroute IMC could reach down to as low as 500ft AGL, with a much higher probability for "helicopter VMC", of which a small patch right above the airfield would suffice.
In the current definition enroute-IR ist of much more use to helicopters than aeroplanes, as the latter are constraint to >1500m flight visibility at both the departure and arrival airfield.
