| The flight control leading edges on modern large aircraft have what type of anti-icing system? | Thermal pneumatic |
| Propellers have what type of de-icing system? | Both A and B are correct=> Chemical and Electric boots |
| The AOA and Pitot tubes use what type of anti-icing system? | Electrical |
| The leading edges on transport aircraft use air provided by | Engine bleed air |
| Which airplane components are protected from ice formations? | Propellers, air data sensors, engine inlet, water and waste lines and flight deck windshield |
| What part of the turbine engine supplies bleed air for thermal pneumatic WAI systems? | engine compressor |
