   Your local time is UTC minus 7 hours. It is 09:00 local time. What time is it in UTC?

   • A1500 UTC
   • B0200 UTC
   • C1600 UTC
   • D0900 UTC

   答案: C. 1600 UTC

   To go from local time to UTC, do the opposite of the UTC-to-local step: add 7 hours, so 09:00 becomes 1600 UTC. Subtracting 7 (0200) goes the wrong way.

    Which set lists the sky condition terms used in Canadian aviation weather?

    • ANIL, SOME, MANY, MOST, ALL
    • BCLR, LOW, MID, HIGH, FULL
    • CSKC, FEW, SCT, BKN, OVC
    • DVFR, MVFR, IFR, LIFR, VLIFR
    显示答案

    答案: C. SKC, FEW, SCT, BKN, OVC

    The sky condition terms are SKC, FEW, SCT, BKN and OVC.

    Your local time is UTC minus 6 hours. A METAR is issued at 1800 UTC. What is the local time?

    • A00:00
    • B12:00
    • C18:00
    • D06:00
    显示答案

    答案: B. 12:00

    Subtract 6 hours from 1800 UTC: 18 minus 6 is 12, so it is 12:00 local time. Adding 6 would go the wrong way.
