FAA Ground School Practice Test

What time should an aircraft departing from an Eastern Daylight Time zone at 0945 EDT land in Coordinated Universal Time after a 2-hour flight?

1. 1445Z

2. 1545Z

3. 1645Z

4. 1745Z

The correct answer is: 1545Z

To find the correct landing time in Coordinated Universal Time (UTC), we first need to convert the departure time from Eastern Daylight Time (EDT) to UTC. During Daylight Saving Time, EDT is UTC minus 4 hours. Therefore, when departing at 0945 EDT, we add 4 hours to convert it to UTC. Starting with 0945 EDT: - 0945 + 0400 (to convert to UTC) = 1345 UTC Next, we account for the flight duration of 2 hours by adding this time to the adjusted departure time: - 1345 UTC + 0200 (duration of the flight) = 1545 UTC Thus, the aircraft will land at 1545Z in Coordinated Universal Time. This makes the selection of 1545Z the correct answer.
