Which airspeed should a pilot use to gain the most altitude in a given period of time after takeoff?

1. Vlo

2. Vx

3. Vy

4. Vs

The correct answer is: Vy

The airspeed that allows a pilot to gain the most altitude in a given period of time after takeoff is Vy, or the best rate of climb speed. This airspeed is specifically designed to achieve the maximum altitude in the shortest amount of time. When a pilot maintains Vy, the aircraft climbs efficiently, balancing the necessary lift with the drag produced, thereby ensuring optimal performance. Other airspeeds serve different purposes. Vlo is typically related to landing gear operations and is not relevant to climbing performance. Vx, while important for gaining the most altitude over the shortest distance, emphasizes horizontal distance more than time. Vs is the stall speed and is crucial for understanding the minimum control airspeed but is not conducive to effective climbing. Therefore, using Vy is the ideal choice when the objective is to maximize altitude gain in a limited timeframe after takeoff.
