FAA Powerplant Written Practice Test

Which statement is true concerning inlet icing of turbine engines?

1. Most turboprop engines rely on electrical anti-icing.

2. All turbine engines are unaffected by cold weather.

3. Inlet icing only occurs during takeoff.

4. Turbine engines never experience icing issues.

The correct answer is: Most turboprop engines rely on electrical anti-icing.

The statement regarding inlet icing of turbine engines that is accurate is that most turboprop engines rely on electrical anti-icing. This is true because turboprop engines, which typically operate in environments where icing can occur, use electrical heating elements to prevent ice from forming on the engine's inlet and critical components. Inlet icing can be a significant concern for turbine engines, particularly when operating in moist, cold air. The electrical anti-icing systems are designed to provide heat to the engine's inlet to ensure proper airflow and maintain performance even in icy conditions. While some other systems may exist, various turbine engines depend on active measures such as this to mitigate the risks associated with icing. It's important to recognize that turbine engines can be affected by icing during various phases of flight, not just during takeoff, and that many turbine engines do have procedures and equipment in place to address icing issues effectively.
