A320 Keep flaps & slats deployed after landing
Just noticed on the A320 CBT it states " If the landing was made in icing conditions or if the runway was contaminated with slush or snow, do not retract the flaps or slats until the ground crew has inspected them for obstruction of snow or ice " . My question is, how does this affect procedures used to indicate hijacking etc. as I thought taxing with flaps lowered was one of several ways of communicating this to atc whilst on the ground.
