Hi all,
Think i just figured out the answer to my question
Vmco = Minumum climb out speed (Guaranteed obstacle clearance)
Vmca2 = Vmca for 2 engine out
Obviously it wants to get to Vmco so it can guarentee an obstacle clearance of 2.5% in the missed approach scenario.
Still the height loss that can be experienced at high operating weights in this aircraft will essentially put you on the ground from a CAT I ILS DH.
Cheers,
