Powerplant–controls and indications, induction system, carburetor and fuel injection, turbocharging, cooling, mounting points, turbine wheels, compressors, deicing, anti-icing, and other related components.
Bottom line
The turbocharger is an exhaust-driven device that raises the pressure and density of the induction air delivered to the engine, and it does not take any horsepower from the engine to operate. Anti-icing equipment prevents ice from forming on certain protected surfaces, while deicing equipment removes ice that has already formed on protected surfaces. The presence of anti-icing and deicing equipment does not necessarily mean the airplane is approved for flight in icing conditions.
Key numbers
| Number | What it means |
|---|---|
| 29–30 "Hg maintained up to the critical altitude in altitude turbocharging (normalizing) | Sea level MAP |
| up to 45 "Hg takeoff manifold pressure in various ground-boosted airplanes | Ground boost |
| up to 40° deviation from windscreen anti-ice electrical current | Compass error |
| minimum 1,000 r.p.m. recommended by some manufacturers for adequate lubrication | Warmup rpm |
