FAA Ground School Practice Test

What is the estimated time en route from the Gila Bend VORTAC to Buckeye VOR with a specified TAS and wind conditions?

1. 10 minutes

2. 13 minutes

3. 15 minutes

4. 20 minutes

The correct answer is: 13 minutes

To determine the estimated time en route from the Gila Bend VORTAC to Buckeye VOR, it's crucial to understand that time en route calculations are based on the distance between the two navigation aids, true airspeed (TAS), and the wind conditions affecting the flight path. Assuming that the distance from Gila Bend VORTAC to Buckeye VOR is known, the time en route can be calculated using the formula: \[ \text{Time} = \frac{\text{Distance}}{\text{Ground Speed}} \] Ground speed is influenced by the true airspeed and the wind. For example, if there is a headwind, the ground speed will be reduced, leading to a longer estimated time to reach the destination, while a tailwind would increase the ground speed, decreasing the time. If the answer given, which is 13 minutes, accurately reflects the calculated time considering both the TAS and the wind direction and speed, it indicates that this value represents a realistic estimation based on typical flight computations. It suggests that all variables have been considered for this situation, leading to a well-rounded answer that helps in planning the flight efficiently while adhering to FAA flight standards. In aviation, pilots constantly perform such calculations to
