Diehl GmbH supplies two types of heated floor panels
for Airbus aircraft:

Flight Deck Floor Heating Panels are an option on some Airbus models. They look like the regular metal floor panels where the pilot and copilot place their feet, but attached to the backside of the panels are a heating pad and a control unit
that's connected to the aircraft's regular AC
power supply.

The control unit has an attached temperature
sensor and contains a thermal circuit breaker,
a printed circuit board, and the power receptacle.
When the aircraft's power is on, the control unit
will keep the floor panel at 18-24°C (64-75°C).

We were going to show you a picture, but if you
were sitting in the cockpit of an A300, would you
be looking at the floor? Me neither. Believe us, they are color coordinated and nothing clashes in the interior design. Just make sure to wipe your feet first!
