Leading edge slats deployed while on stand?
Hello - a bit of a nerdy question if I may.
Yesterday while waiting for the BA665 at Larnaca I noticed the aircraft (an A320) was parked on its stand with its lead-edge slats (if that is the term) in the 'out' position (i.e. the position they are put in during take off and landing). I thought it was normal practice for these to be retracted after landing, and then deployed again before take off.
At least one of the other aircraft parked on stand was also in this configuration.
Might there be a reason for this?
