Which instrument panel lights indicate maximum acceleration under various flight conditions?

Which instrument panel lights indicate maximum acceleration under various flight conditions?

• A. G-LIMIT LIGHTS
• B. ACCEL LIMIT LIGHTS
• C. LIMIT LOAD LIGHTS
• D. SPEED LIMIT LIGHTS

Answer: (C)

Limit load lights indicate when the airframe is approaching its maximum structural load, which corresponds to the highest acceleration (load factor) the helicopter can safely experience under the current configuration and flight conditions. As you maneuver, gusts, weight, and center of gravity change the load factor, and these lights warn you to ease or adjust to stay within safe limits across the whole flight envelope. G-limit lights would signal a specific g-value exceedance, which is a related but separate concept. Speed limit lights pertain to airspeed restrictions, not acceleration. An accel limit light isn’t the standard designation for this helicopter’s panel.
