Show the answer and explanation

Correct answer: A. Usually 122.8, verified on the sectional chart or in the Chart Supplement U.S.

  • A — correct The guide says most non-towered airports have a UNICOM frequency, usually 122.8, but the remote pilot should always check the Chart Supplement U.S. or sectional chart for the correct frequency.
  • B — incorrect 122.9 is the MULTICOM frequency, used only when a non-towered airport has no FSS, UNICOM, or other frequency listed.
  • C — incorrect The guide states that these frequencies are found on the sectional chart by the airport or in the Chart Supplements publication from the FAA.

BACKGROUND

UNICOM is a nongovernment air/ground radio communication station that may provide airport information at public-use airports where there is no tower or flight service station (FSS). The study guide explains that most non-towered airports have a UNICOM frequency, which is usually 122.8. The frequency can vary when there are many non-towered airports in an area, so the remote pilot should always check the Chart Supplement U.S. or the sectional chart for the correct one. For non-towered airports with no UNICOM or any other frequency listed, the MULTICOM frequency of 122.9 is used instead.

STUDY TIP

Pair the two numbers: 122.8 is the usual UNICOM, 122.9 is MULTICOM for airports with no listed frequency. Always confirm on the chart or in the Chart Supplement U.S.

KEY POINTS

  • Most non-towered airports have a UNICOM frequency, usually 122.8.
  • The frequency can vary, so verify it on the sectional chart or Chart Supplement U.S.
  • UNICOM is a nongovernment air/ground station at airports with no tower or FSS.
