Why is best rate of climb speed generally preferred over best angle speed during initial climb?

Best rate of climb speed is generally preferred during initial climb because it allows an aircraft to gain the greatest altitude in the shortest period of time. This is particularly important in the early stages of flight when the aircraft needs to clear obstacles, such as buildings and terrain, as quickly as possible.

By flying at this speed, the aircraft can achieve the most efficient vertical ascent, making it advantageous for pilots to reach a safe altitude rapidly. This is crucial for safety and operational efficiency, especially in environments with potential obstacles.

Other aspects, such as maximizing fuel economy or ensuring safe maneuverability, play important roles at different phases of flight, but for initial climb specifically, the primary objective is effective altitude gain in the least time. Therefore, the correct choice highlights the necessity of speed for optimizing altitude acquisition during the crucial initial climb phase.
