@ #2: Most firetrainers (i.e. structures that are set on fire externally in order to train the fire brigade on how to extinguish it) are custom made of steel. Usually they are all-steel structures (i.e. no rubber, plastic or similar) having the full height of an aircraft but a much shorter fuselage. Fire is either produced by gas or by flammable liquids. Gas has the advantage that one can ingite it once again after it was extinguished (making life for the firefighters a bit more difficult and interesting).
On the contrary, actual airframes are often used for evacuation training (and I don´t mean those certification tests but ongoing training of any personnell). Stuttgart (STR
) has an disused Tu-154 for this purpose. Just search A.net´s database for "D-AFSG" as registration; there are 11 pic´s.
For firefighting training inside an aircraft, the fire brigade at FRA
has a portable, customized standard-container (whats the designation of those ? 30ft ?) with gas-hook-ups. This one can make the interior really hot !
It is also used by other airports; they just put it (including crew) onto a truck and transport it around (not too long ago it was in HAJ
