Part 107 weather practice test

20 questions on the FAA testing supplement's weather reports · Updated October 6, 2026

Weather is 11–16% of the test. Most of it is reading coded reports: a METAR tells you what the weather is now, a TAF what it is forecast to be. The reports below are the ones printed in the FAA testing supplement you get on test day.

What this test covers

Decoding METARs (wind, visibility, weather, clouds, ceiling, temperature and altimeter), reading TAF change groups (FM, TEMPO, BECMG, PROB), and how density altitude affects your drone. New to the codes? Read how to read a METAR first; it has a decoder you can tap through.

Question 20 of 20 · Weather

What effect does high density altitude have on the efficiency of a small UA's propellers?

  1. APropeller efficiency increases
  2. BPropeller efficiency decreases
  3. CDensity altitude has no effect on propellers
Show answer

B. Propeller efficiency decreases

Thinner air gives the propellers less air to work with, so thrust, lift and overall performance decrease as density altitude rises.

The weather ideas people miss most

  • The ceiling is the lowest broken or overcast layer. Few and scattered clouds never form a ceiling, however low they are.
  • Cloud heights are above the ground. OVC007 is 700 feet AGL, not MSL.
  • Times are in UTC (Zulu). 1218/1324 means from 1800Z on the 12th to 2400Z on the 13th.
  • FM is a lasting change, TEMPO a temporary one. TEMPO conditions come and go for less than an hour at a time.
