High thrust operation on A320
As a fuel saving measure on the A320 (and all other a/c...) you can shut down the engine #2 during taxi-in.
Normally a 3 minute cool down period is considered before shutting down the engine. Books say that 3 minutes need to be considered after "high thrust operation". What is that?
Do we need to take 3 minutes, only after a landing where full reverse was used?
Or also after a landing with idle reverse? In this case the highest thrust has been on the ILS, in normal conditions around 45% N1.
Any idea?
