In emergency operations, how many actuators control the slats?

In emergency operations for the Dassault Falcon 2000LXS, the correct answer indicates that there is one actuator that is capable of extending the slats but not retracting them. This design provides a measure of safety and redundancy in situations where full functionality may be compromised.

Having a single actuator for extending the slats ensures that, even in the event of a failure, pilots can still deploy the slats to enhance lift during critical flight phases, such as takeoff or landing. However, the limitation that it cannot retract the slats under these conditions suggests a focus on maintaining the safety of the aircraft, allowing for a more controlled descent or approach even if the aircraft cannot return to a fully configured state.

The other options imply either additional functionality or non-operation, which may not align with the design parameters intended for emergency scenarios in this aircraft model. Therefore, understanding that one actuator operates in a limited capacity during emergencies provides insight into the aircraft's safety features and operational protocols.
