Remember to set your clocks forward one hour this weekend. The time changes to daylight-saving time Sunday morning at 2 a.m. local. You might lose an hour of sleep, but you'll gain more daylight during the evening, and that means more time for relaxing flights after work.
You'll also need to adjust your local-to-Zulu time conversion formula. The FAA uses Coordinated Universal Time (UTC) or Zulu time for many operations, including air traffic control, flight plans, and weather reports. Print this handy chart to help you remember which conversion formula to use.
If you live in the Eastern Time Zone portion of Indiana, Arizona, or Hawaii, you won't need to change the time. The Eastern portion of Indiana does not change time and "falls back" into the Central Time Zone, Zulu minus 5. Arizona "shifts" to Pacific Daylight Time, or Zulu minus 7 hours. Hawaii remains Zulu minus 10 hours.
