It's best to know ahead of time and be prepared because these moments will happen during a critical phase of flight where time is of the essence.
Situation: Initial altitude 5000 feet. Then, at 2000 feet, ATC clears you unrestricted to FL230.
Remember: Set the altitude, but do not pull for open climb until you are 'out of' SRS…but what if you forget and pull early?
Recovery: If you accidentally pull open climb while still in SRS….Select speed and roll back to V2 plus ‘a handful’. This will keep the nose up and protect you from busting your noise abatement procedure.
Situation: You’re being vectored into an intercept heading and the pilot monitoring accidentally deletes one too many points and you lose everything. You are looking at PPOS, route discontinuity and blank, blank, blank.
Recovery: Type in ABC over the route discontinuity. Select lateral revision (you can't make a lateral revision off a PPOS) Select New Destination. Insert approach, and delete ABC... and you’re good to go.
Situation: You forgot to activate the approach and selected managed speed on final, and your power surges forward.
Recovery: Fifi is just an airplane. Pull the thrust levers back and ask your partner to activate the approach, then reengage.
Situation: The airplane has already altitude acquired ALT* and you change your FCU altitude, she reverts to V/S.
Recovery: Pull open climb or descent so she continues to climb.
Guys... how to get out of trouble if you tell your wife or girlfriend the wrong thing... be prepared and have a recovery plan. Chocolate, Red Wine and and a good back rub is a good place to start.
Enjoy the Journey!
