As a Civvy - never done a towering IF departure in a relatively 'modern' aircraft with an excellent ap.
As a Mil pilot, did quite a few in a dinosaur aircraft with non-existent auto-pilot.
We all know that the accepted/approved/trained procedure for PC2DLE is 250m RVR, clear of obstructions etc etc, no reject option as you ain't landing back on the deck.
Done many VMC departures using the IF/Visual scan in pitch black with no discernible horizon.............but the fudge is definitely 250m RVR.
Which is laughable - on one departure I swear it was more like 240m but we vowed not to tell anyone.
I remember one shag suggesting they ask the rescue vessel to station at 250m until someone highlighted the 'obstruction-like' qualities of such a vessel, right where you would not want him.
This is old hat - fudge will continue until Mr Tesla and Mr Solar Panel save the world from our addiction to carbon fuels or the OEMs provide a suitable aircraft which the energy companies are mandated to use.
