If the "Speed" warning light activates, what action should be taken?

When the "Speed" warning light activates, it indicates that the aircraft is experiencing a situation that could lead to a stall or other aerodynamic problems due to low airspeed. In such a scenario, the immediate priority is to respond quickly to rectify the conditions that triggered the warning. Initiating corrective actions immediately is critical because it helps restore safe flying conditions by addressing the root cause of the warning. This could involve adjusting the aircraft's configuration, such as increasing speed through throttle adjustments or reducing drag, rather than waiting or taking less direct actions.

Taking earlier actions to correct the airspeed keeps control of the aircraft within safe limits. While other options like preparing for an emergency landing or reducing throttle could be relevant in different contexts, they may not directly address the immediate need to regain or maintain proper speed in the air. Thus, prompt action to correct the situation is the best approach when faced with this warning.
