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

What occurs when any thrust lever is advanced to TOGA?

1. The landing gear retracts.

2. The GLD devices retract and the system is rearms.

3. The engine starts to spool faster.

4. The hydraulic pressure increases.

The correct answer is: The GLD devices retract and the system is rearms.

When any thrust lever is advanced to TOGA (Takeoff/Go-Around), the engine starts to spool faster. This is the correct understanding of what occurs with the thrust lever position. Advancing the thrust lever to the TOGA position commands the engines to enter a higher thrust mode, which results in an increase in engine power output necessary for takeoff or initiating a go-around maneuver. In this context, the increasing engine thrust is crucial for providing the necessary lift and performance during critical phases of flight. Factors such as gear retraction, system rearms, and hydraulic pressure changes do not take precedence with this throttle input in the same instant as the engine response. Therefore, when you push the thrust lever to TOGA, the engines react by spooling up faster to deliver enhanced thrust. This is a fundamental operation in modern aircraft systems, especially during takeoff or go-around situations where additional power is required.
