'J Tulla' that's the biggest issue with any twin that can't out-climb the terrain on two donks never lone one during climb to LSALT. I've always believed that you fly the plane to suit the environment. A dept in CAVOK means you just get on with it but in IMC/NGT make sure you have an 'out' from the time you push up the throttles even if it means staying within gliding distance of the dept AD whilst getting to LSALT.
As for risks colliding with another A/C on say a reverse DGA..........well some good airman-ship & common sense is yr best defense, both not always exhibited sadly.
