FAA Ground School Practice Test

What indicated airspeed is needed to reach Point B on schedule given the cross-country flight time?

1. 117 knots

2. 137 knots

3. 150 knots

4. 125 knots

The correct answer is: 137 knots

To determine the indicated airspeed needed to reach Point B on schedule, it's critical to understand the relationship between groundspeed, indicated airspeed, wind conditions, and flight time. Given that the indicated airspeed is influenced by various factors, including altitude, temperature, and wind, the chosen option of 137 knots suggests that this speed is optimal for the specific flight plan and conditions. This indicated airspeed helps to ensure that the aircraft can compensate for any headwinds or maintain a desirable groundspeed while adhering to the scheduled time of arrival. Calculating the required airspeed typically involves considering the distance to be covered, the estimated time of arrival, and any expected environmental influences like wind. An indicated airspeed of 137 knots signifies that while the aircraft may face winds, this speed will enable it to maintain the necessary groundspeed to arrive at Point B as planned. Understanding this computation is crucial for flight planning, as it allows pilots to adjust their speed effectively based on conditions to meet time constraints.
