Absolutely! The Airbus term for this mod is SETWA. Single Engine Taxi Without APU.
During the Emergency Evacuation drill, pre-mod aircraft will only have only one squib light illuminated once all Fire p/b's are pushed.
SETWA aircraft will have both squib lights on.
This is an interesting gotcha for us, as all our aircraft are modified, but our Sims aren't! Pet question from our TRIs!
