captain_jeeves, well fair enough. So now we have agreed that a pilot does have a choice upon executing a go around. Why not to have a choice upon a take off? It wasn't possible while using the RTOW charts, I agree, but after introducing the performance software one is certainly capable of just punching in the required data and see if you can make it? If you have read the previous posts you might have noticed that the execution of special EOSID was a must regardless of performance data. In other words no matter whether the take off performance is met or not follow the special EOSID in case of engine failure and IMC. Apart from legal aspects its not always the safest solution like in CDG where one will face much bigger problems turning into active parallel RWY. It only makes sense of course if in advance the PIC has made sure that he can follow the SID in case of single engine. This capability is given throughout the new software tool but we aren't using it. Why? don't know? Unless the obstacle is temporarily man made its been there for while isn't it? In case of man made obstacle one has got to punch it in anyway, like i recall the case in LGW with protruding aircraft tails.
Cheers.
