Once the instructor indicates they are ready to close class, what command does the Flight Leader give?

The appropriate response when an instructor indicates they are ready to close class is to convey a sense of organization and readiness for dismissal. By giving the command "Flight, prepare for dismissal," the Flight Leader establishes a clear transition from the class setting to a more informal environment. This command not only signals to the Flight members that the class is concluding but also prepares them to follow any further instructions or to exit the class in an orderly manner.

The other options do not capture the necessary organizational tone and readiness. For instance, saying "Class is dismissed" may be overly abrupt and lacks the preparation aspect needed for a smooth transition. "Attention, class" is more suitable for gaining focus and does not pertain to ending the session. "Stand down" is typically used to relax a formation or to end a more formal action, but in this context related to class conclusion, it may not effectively communicate the needed preparatory commands.
