i.e. in go-around situation, reverser started to deploy, pilot choses to go-around
the A320 FCOM/FCTM is pretty clear about that
- After the flight crew selects reverse thrust, they must perform a full stop landing. (FCOM/PRO/NOR/SOP/Landing/LANDING)
- In any case, if reverse thrust has been applied, a full stop landing must be completed. (FCTM/NO/NO 180-GO AROUND/REJECTED LANDING)
there is also an article about that topic available in issue 14 of Airbus' Safety First magazine
