FAA Ground School Practice Test

For an aircraft departing from the Pacific Standard Time zone at 0600 PST and traveling for 4 hours to the Mountain Standard Time zone, what local landing time will be?

1. 1000MST

2. 1100MST

3. 1200MST

4. 0900MST

The correct answer is: 1000MST

To determine the local landing time for an aircraft departing from the Pacific Standard Time (PST) zone at 0600 and traveling for 4 hours to the Mountain Standard Time (MST) zone, we must account for the time difference between these two time zones and the duration of the flight. Pacific Standard Time (UTC-8) is one hour behind Mountain Standard Time (UTC-7). When the aircraft departs at 0600 PST, this time is converted to MST by adding one hour, making it 0700 MST at the moment of departure. Then, by adding the flight duration of 4 hours to the departure time in MST, we calculate the landing time: - 0700 MST (departure time in MST) + 4 hours = 1100 MST. Therefore, the aircraft will land at 1100 MST. This aligns with the correct answer. Understanding the relationship between the time zones and accurately performing the addition of flight time to the adjusted departure time is essential for arriving at the correct local landing time.
