What does Climbout Speed (Vco) signify?

• A. The speed needed for a stabilized climb
• B. The planned speed for single-engine climbout before an obstacle
• C. The speed for making a steep turn
• D. The minimum speed for descent

Answer: (B)

Climbout Speed (Vco) is critically important during a single-engine climbout, especially when faced with obstacles. This speed is specifically designed to ensure that the aircraft can safely and efficiently clear any potential obstacles while maintaining a proper climb rate. It accounts for factors like optimal engine performance and aircraft configuration necessary to handle the added aerodynamic and power demands in a single-engine scenario. In this context, Vco not only provides a safety buffer but also reflects the pilot's knowledge of the necessary speed to transition effectively from the ground to a climbing phase while ensuring the aircraft can respond adequately to engine failures or other potential emergencies. This speed is predetermined based on flight test data, performance charts, and aircraft limitations, ensuring that the aircraft performs as expected. The other choices do not accurately define Vco. For example, while stabilized climb speeds are important, Vco is specifically tailored for a single-engine climbout before obstacles, making option B the most accurate reflection of the term's significance.
