Also worth mentioning are the gotchas on engine failure on departure vaguely related to this..
1) Lets say you have entered the Climb phase on the FMGS, thrust is back at climb, aircraft accelerating towards characteristic speed ready for flap retraction. At this point the engine fails. You select TOGA. Flap is still out. The aircraft will now be in MAN TOGA SRS GA TRACK!!! Selecting MCT only will prevent this
2) Flap 3 departure, airfield with close in terrain. You are accelerating after take off, past F speed, Flap selected 1. Engine now fails.
You select a heading to take you away from terrain, however because you are below characteristic speed (in this case 'S') your auto pilot AOB limit is 15 degrees! Any turn will be very wide unless you manually fly it.
We covered this in the last sim session, I found it a very interesting and thought provoking topic.
