What indicated airspeed at 3,000 feet would result in the greatest increase in altitude for a given distance?

• A. 80 KIAS
• B. 94 KIAS
• C. 100 KIAS
• D. 90 KIAS

Answer: (B)

The indicated airspeed that results in the greatest increase in altitude for a given distance is typically known as the "best rate of climb speed," or Vy. This speed is specifically designed to maximize altitude gain over time, which translates to the most efficient climb over horizontal distance.

In this case, a speed of 94 KIAS is the speed that achieves this optimal balance. At this airspeed, the aircraft generates sufficient lift to climb effectively while minimizing drag. Climbing at this optimal speed means that for every unit of distance traveled forward, the aircraft will gain the most altitude compared to other speeds.

While the other speeds may allow for climbing as well, they may result in less efficient climb performance either due to higher drag (as with speeds that are either too high) or insufficient lift (as with speeds that are too low). Therefore, 94 KIAS is identified as the best option for achieving the greatest altitude increase over a specified distance.
