Lab 1
Directions:
This is a three part assignment. The goal is to become comfortable reading raw METARs and TAFs. You will look at the METARs and TAFs for each day and answer the corresponding questions.
If you already know how to read a METAR and a TAF, this assignment will be a cakewalk for you. If you've relied on ForeFlight to decode them, what are you going to do when you get into an airplane with XM weather or ADS-B in that does not decode the weather? You'll look back fondly on this assignment!

1. METAR time (Translate this to local time.) 02:53 P.M
2. METAR winds
3. METAR visibility
4. Prevailing Weather (Any precipitation or weather phenomena)
5. METAR clouds (Include what this means. For example, if the METAR says BKN006 you should include what portion of the sky is covered and whether the height given is AGL or MSL.)
6. METAR temperature and dewpoint. (Include units)
7. METAR altimeter setting (Include units)

9. Is there anything in the RMK section of the METAR that concerns you? What could be the potential outcome?
10. Are the METAR conditions LIFR, IFR, MVFR, or VFR?
11. TAF issuance date/time (Convert to local time)
12. TAF valid period. (Convert to local time)
13. You are planning to fly a Cirrus SR20 at 1430Z. According to the TAF, what are the prevailing winds?
14. Is the TAF for your time of flight (14:30Z) LIFR, IFR, MVFR, or VFR?
15. Compare the METAR with the line in the TAF that is supposed to be current at 14:30Z. Are there parts of the forecast that are correct? Are there some incorrect? Be specific.
16. You opt to push your flight back to 2100Z. What is the prevailing weather?

9. Are the METAR conditions LIFR, IFR, MVFR, or VFR?
10. TAF issuance date/time (Convert to local time)
11. TAF valid period. (Convert to local time)
12. Given the rapid change from good conditions to poor conditions at 2200Z in the TAF and the fact that the forecast is for April in Michigan, what type of front do you think moved in during this forecasted period?
13. If said front moved into the area would you expect the weather in Grand Rapids, MI (37NM North) to be vastly different than that in Battle Creek?

10. Given the remarks section in the METAR, would you expect these conditions to exist for much longer? Why or why not?
