So T/C are similar to turbochargers ? Using hot compressed bleed air from the engine to compress fresh air for the cabin ?
What is the benefit from doing so, and not using the bleed air directly ? Cabin air contamination ? Why don´t we have T/C any more ?
What air do you use for deeicing on such airplanes ? Direct bleed air ? Precooled bleed air ? Exhaust bleed air comming from the turbine of the T/C ?
