What is the Vmo speed limit for the aircraft?

The Vmo speed limit for the aircraft is indeed 240 knots. This limit is crucial as it represents the maximum operating limit speed above which the aircraft should not be flown. Exceeding Vmo can lead to structural failure or control difficulties because the aerodynamic forces on the aircraft change significantly at higher speeds. Each aircraft has specific limitations set by its manufacturer which are based on extensive testing, and these limitations ensure safe flight operations.

In this case, the choice indicating 240 knots aligns with the operational specifications necessary for maintaining structural integrity and safe maneuverability during all flight phases. Understanding Vmo is essential for pilots to effectively manage airspeed during ascent, cruise, and descent, ensuring adherence to safety protocols outlined in operational guidelines.
