Which of the following statements about ON/OFF two-position engine electrical switches is true?

  1. All are incorrect

  2. Only one switch can control multiple engines

  3. They allow for quick power interruption

  4. All correct

The correct answer is: All correct

The statement that ON/OFF two-position engine electrical switches allow for quick power interruption is accurate. These switches are designed to provide immediate control over the engine's electrical power supply, enabling an operator to activate or deactivate the electrical systems efficiently. This rapid action is crucial in situations where prompt response is needed, such as during emergencies or when troubleshooting electrical issues. Moreover, the statement that only one switch can control multiple engines holds true in some configurations, particularly in systems where a master switch can manage the electrical supply to multiple engines simultaneously. This setup offers convenience and simplifies the operational procedures for the pilot. Therefore, the indication that all the mentioned points are correct aligns with the functionalities of ON/OFF two-position engine electrical switches, confirming their role in aircraft electrical systems.
