If you're descending on the ILS through say 2800 feet and the missed approach altitude is 2000 on the missed approach procedure and you have 2000 set on the FCU, if ATC orders you to go around and you push TOGA, what would the FMA read? In this case if you don't change the altitude selection on the FCU would SRS remain engaged (if you do nothing about it) as there is no altitude to capture?
In the above case, what's the best way to fly the missed approach procedure? Selecting TOGA seems necessary to engage the GA phase and sequence the missed approach procedure in the FMGS, but on the other hand TOGA thrust isn't quite necessary at that altitude for passenger comfort, etc.
Any advice?
