Imagine, you need toga during your... initial climb for whatever reason, and the thing switching to go-around modes...("GO TRK ..."). Not nice engineers thought.
Not nice but it does happen.
If you set TOGA during the initial climb after take-off (still with some flap out) (OPEN CLIMB) it will give you the go around mode, as I discovered by surprise once, however the FMGS was still in the CLIMB phase
Why does setting TOGA during the "initial climb" phase give you the Go Around if you are still in the "CLIMB phase". You might say you get the Go Around mode because you meet all the preconditions for engagement (as listed above), but why would you ever want the Go Around mode during the Climb phase, if its all to do with phase ?
Why would the FMGS ever be designed so that it will go into the GO AROUND mode during the CLIMB phase ?
Why would you ever need the GO AROUND mode ever during the CLIMB phase ?
If its all to with the phase of flight, then shouldn't the Go Around mode only be available only during the APPROACH (and DESCENT) phase (which sounds logical), and not during the CLIMB phase as well.
If GO AROUND mode is not available during the takeoff phase, then it should not also be available during the climb phase as well, but it is.
