Certified Flight Instructor - Flight Instructor Airplane Practice Exam

What is the indicated airspeed required to reach a point Y from point X on schedule given specific conditions?

1. 138 knots.

2. 143 knots.

3. 162 knots.

4. 150 knots.

The correct answer is: 143 knots.

To determine the indicated airspeed necessary to reach point Y from point X on schedule, it is essential to consider the flight conditions, including distance, weather, and wind factors. The indicated airspeed is calculated by taking into account the ground speed required to cover that distance within a specified time frame, factoring in any wind components that may affect the aircraft's performance. In this scenario, an airspeed of 143 knots may have been derived based on calculations that incorporated the specific conditions of the flight. This would involve determining the time needed to cover the distance while considering any headwinds or tailwinds that could affect the true airspeed required to maintain the schedule. The indicated airspeed is the speed shown on the aircraft's airspeed indicator, adjusted for altitude and temperature, which affects air density and, subsequently, true airspeed. Thus, achieving the indicated airspeed of 143 knots allows the aircraft to maintain the necessary trajectory and meet the scheduled arrival time while effectively compensating for the environmental conditions present during the flight.
