Thank you for the replies.
The 48 Degrees PL is not in my QRH (dated 2009?/2010?)
(29 Degrees to simulate feathered engine on 72)
I've tried not feathering the engine with engine cut at V1. Struggled just to reach 400ft (ISA +15, Max TO weight, Sea level) but it did climb.
Full rudder with bank on live engine just to keep it straight.
The practical side of it is understood.
What's buggering me is this part:
No action will be taken (apart from depressing MC/MW pushbutton):
-until flight path is stabilized.
-under 400 ft above runway, except propeller feathering after engine failure during approach at reduced power if go around is considered
If there is no uptrim on the live engine, the memory item calls to push the power up.
But is silent on feathering the dead engine until ABOVE 400ft.
