On other occasions there will be some good indication the crew could work with. Applying TOGA+15 indiscriminately and reactively, without trying to assess the situation first and trying to make sense of it, is actually plain wrong. And the book confirms that in writing. Problem with TOGA + 15 is the performance, ATC liaison and altitude control. Not to sidetrack too much, we all know that dual engine GA are an identified weak spot of pilot performance worldwide - the reasons and effects are of the same ilk here, in my opinion. Also, simulator experience shows that
When close to ground when your FD could be wrong is not a situation that affects flight path? UAS is May Day. We are not going round where there's large flight path and thrust change, we are airborne and climbing may be with TOGA, we just want to ensure that without the possible misguidense by FD. Keeping FLEX is not a problem but following FD could be dangerous.
