RL77CHC - the technique you describe is exactly how I, as an ex-mil pilot, would have done it but what is the legality of flying the aircraft manually (even if you are following the blue lines on the FD) below VminI?
If you were using the GA/TU of the later phases of software then fine but you are trying to fly an IMC profile below VminI.
I'm not saying it is difficult, because it isn't if you have been trained for it and checked on it, just asking why it doesn't form part of the IR.
The reports about the pilot not being happy to fly the aircraft due to engine issues could lead to distraction during a tricky departure when you are already under pressure.
