@dash6 -
I'm not against using the TOGA switches if the situation calls for it. For low altitude G/A's it ** IS ** the correct procedure.
Is this case it should have been used but once the situation became less than ideal the basic option of cycling the FD's, establishing a known A/P mode(verified by FMA) and A/T or manual thrust configuration would have made this a minor event that the crew could have talked about afterwards.
Deselecting the FD's and reselecting them covers multiple situations after the A/P is in engaged in the approach mode. Especially if the approach clearance is cancelled or modified after LOC/GS capture.
Had to deselect and reselect the FD's sometime this summer. I forget the details but it takes approx. maybe 10 seconds to reestablish a desired, and known(just selected/verified mode), automation mode.
