I see many times A320 AOA sensor pointing to up position after landing.
Any one could explain me why. many thanks

I've never worked on the A320, but the AoA sensors that I've come across rely on airflow, so on the ground with the aircraft stationary, the AoA indicator just points to wherever the sensor is positioned.

If its a 'flying wing' design, then I suspect gravity is simply acting on the heaviest bit and making it point skywards...

Doubles up as a heavy landing indicator... sorry.:p

Most aoa vanes are free to move at all times with just a little friction so they go where the airflow takes them. It takes very little to move them with a gust of wind or good bump.
