Maximum speed at sea level is what?

Maximum speed at sea level is what?

• A. 100 knots
• B. 120 knots
• C. 110 knots
• D. 115 knots

Answer: (C)

Aircraft speed limits are set to protect the airframe from flutter and structural stress, and they’re published as the maximum operating speed. At lower altitudes, this limit is given in knots of indicated airspeed. For sea level, the published value represents the highest IAS you can safely fly before reaching the airframe’s limit. In this case, the sea‑level limit is 110 knots, so you should not exceed 110 knots indicated airspeed when near the surface. As you climb, the limit typically changes—often decreasing or switching to a Mach limit—so always check the flight manual for the exact values at different altitudes.
