What is the equivilent of floor heating in commercial aircraft.?

Question

I know there are a lot of ex-military retired commercial pilots out there, or in here. Military aircraft had floor heating. What is the civilian counterpart to that function?

Answer 1

The modern engineering concepts in aircraft design, especially commercial, cater for over all comfort of the passengers. This area of design is so carefully tailored that the cabin remains at the most comfortable conditions for long relaxed journeys. It is much like the 'climate control' in automobiles as compared to the standard AC. The inherent ambience is a result of routing the heated/cool air through a system of ducts and passages which precludes heating/cooling of any specific surfaces or areas. Further, with the advanced insulation techniques, the temperature is spread and maintained uniformly throughout the cabin.

A system of ducts and outlets below the passenger area and in the cargo hold also help in maintaining the floors at comfortable levels. This, perhaps, is the equivalent of your military aircraft floor heating.

Answer 2

Modern commercial aircraft have no such ability. Cabin heating is accomplished through engine bleed air routed through heat exchangers thus warming the cabin air. The closet thing to floor heating that I am aware of is on older 727 aircraft the cargo compartments had linings which were heated with insulated electric elements for the comfort of any live animals being shipped.
