Which control is used to reengage the backup SAS after disconnection?

• A. The Big button next to reset
• B. The 4-Way toggle
• C. The SAS Activation lever
• D. The AFCS engage switch

Answer: (C)

Reengaging a disconnected stabilization augmentation system is done with the control specifically labeled to restart that system. The SAS Activation lever is the control designed to turn the Stabilization Augmentation System back on after a disconnection. Moving it to the activate or on position reinitializes the SAS, restoring its stabilizing commands to the flight controls and helping you regain the intended handling characteristics.

The other controls aren’t for this particular action. The big button next to reset is not used to reenable SAS; it’s typically a reset function for a fault or memory. The 4-Way toggle isn’t the SAS reengage control either; it serves a different input or mode purpose. The AFCS engage switch relates to the Automatic Flight Control System as a whole (like autopilot), not the SAS by itself, so it wouldn’t selectively reengage the backup SAS.
