What is the first action to take when a FLAPS CAS message is displayed?

• A. Check the circuit breaker
• B. Reset the electronic control unit
• C. Recycle the landing gear
• D. Contact ATC

Answer: (A)

A FLAPS CAS warning points to a fault in the flap control/electrical system, so the quickest, most effective first action is to check the flap circuit breaker. A tripped breaker is a very common cause of this alert, and resetting it (if it is found tripped) can restore normal flap operation if the fault was simply an electrical trip. This approach quickly determines whether the issue is a simple circuit problem or something more serious, without unnecessary manipulation of the system.

If the circuit breaker isn’t tripped or resetting doesn’t clear the alert, then follow the non-normal procedures outlined in the flight manual and handle the situation accordingly. Other actions like resetting the electronic control unit, cycling the landing gear, or contacting ATC don’t address the underlying electrical fault indicated by the CAS and aren’t the appropriate first step.
