PSA Airlines Canadair Regional Jet Systems (PSA-CRJ) Practice Exam

What must the pilot do after deploying the ADG to restore the AC ESS Bus?

1. Activate the APU

2. Stow the ADG Manual Deploy Handle and press the PWR TXFER OVERRIDE button

3. The pilot does nothing

4. Manually reset the bus on the control panel

The correct answer is: Stow the ADG Manual Deploy Handle and press the PWR TXFER OVERRIDE button

When the pilot deploys the Air Driven Generator (ADG), the primary goal is to restore electrical power, specifically to the AC ESS Bus, which is crucial for essential aircraft systems. Once the ADG is deployed and functioning correctly, the pilot must take specific steps to ensure that the power transfer is properly established and that the aircraft gains maximum efficiency from its power sources. The correct action involves stowing the ADG Manual Deploy Handle and pressing the PWR TXFER OVERRIDE button. This process is essential as it ensures that the ADG can properly transfer power to the AC ESS Bus after deployment. The stowing of the handle prevents any accidental re-deployment of the ADG, while the PWR TXFER OVERRIDE button is a critical component that allows the pilot to manage the power transfer effectively. By completing these actions, the pilot facilitates the integration of the ADG's power into the aircraft's electrical system, thus ensuring that the necessary bus receives power and operates effectively. This process is integral for maintaining the safety and functionality of onboard systems, especially when the aircraft is in a compromised electrical situation.
