What is the purpose of an airspeed margin indicator?

• A. To show current fuel consumption
• B. To indicate weather changes
• C. To show the relationship between current airspeed and stall speed
• D. To display GPS coordinates

Answer: (C)

The purpose of an airspeed margin indicator is to show the relationship between current airspeed and stall speed. This indicator provides critical information regarding the safety of the flight by displaying how close the aircraft is to its stall speed, which is the speed at which the aircraft can no longer maintain level flight. By monitoring this relationship, pilots can adjust their flying conditions—such as altitude and maneuvers—to ensure they remain safely above stall speed, reducing the risk of an aerodynamic stall. Understanding the airspeed margins helps pilots make informed decisions, especially during critical phases of flight like takeoff and landing, where maintaining adequate airspeed is essential for safe operations. The airspeed margin indicator is an important tool in enhancing situational awareness and operational safety.
