QUESTIONA remote pilot obtains a newly revised Chart Supplement U.S. Based on the revision cycle in the study guide, about how many weeks will pass before the next revised edition is issued?

  1. A8 weeks
  2. B4 weeks
  3. C26 weeks (about six months)
Show the answer and explanation

Correct answer: A. 8 weeks

  • A — correct The Chart Supplement U.S. is revised every 56 days, and 56 days divided by 7 days per week is 8 weeks.
  • B — incorrect 4 weeks is only 28 days, half of the 56-day revision cycle.
  • C — incorrect A six-month cycle is the semiannual revision schedule of sectional charts, not the Chart Supplement U.S.

BACKGROUND

The study guide states that the Chart Supplement U.S. is published in seven books organized by regions and is revised every 56 days. Converting that cycle to weeks gives 56 ÷ 7 = 8 weeks between editions. This is much shorter than the semiannual revision cycle of sectional charts, which is why the Chart Supplement carries more current airport details, although still not same-day changes, which appear in Notices to Airmen (NOTAMs). The publication covers airports, heliports, and seaplane bases open to the public and is also available digitally from the FAA.

STUDY TIP

Memorize 56 days and be ready to see it expressed as 8 weeks; the test may present the cycle in either unit.

KEY POINTS

  • The Chart Supplement U.S. is revised every 56 days.
  • 56 days equals 8 weeks.
  • Sectional charts are revised semiannually, a much longer cycle.
