Part 107 Frequencies/Communications

(Refer to Figure 22, Area 2.) At Coer D'Alene, which frequency should be used as a Common Traffic AdvisoryFrequency (CTAF) to monitor airport traffic?

• 122.05 MHz.

• 135.075 MHz

• 122.8 MHz

Answer explanation

The CTAF is ued for carrying out airport advisory practices and/or postition reporting at an uncontrolled airport (Which may also occur during hours when a tower is closed). The CTAF may be a UNICOM, MULTICOM, FSS, or tower frequency and is identified in the appropriate aeronautical publications. On charts, CTAF is indicated by a solid dot with the letter "C" inside. When the control tower operates part time and a UNICOM frequency is provided, use the UNICOM frequency.

(Refer to Figure 52). On what frequency can you expect to monitor air traffic ina and around Lincoln airport?

• 118.5

• 122.95

• 124.0

Answer explanation

The communications section of the Chart Supplement U.S. for Lincoln Airport lists 118.5 as the tower freqency and the CTAF when the tower is closed. When operating in the vicinity of an airport, remote pilots are encouraged to monitor the tower frequency or CTAF.

(Refer to Figure 20, Area 3.) You need to operate your sUAS in close proximity of the Elizabeth City CGAS RGL (ECG) Airport. What frequency should be used to contact ATC?

• 122.95

• 124.375

• 120.50

Answer explanation

Accoeding to the chart, the ATC control tower frequency is 120.50.

(Refer to Figure 24, Area 1.) How close can teh Remote PIC fly their sUAS to the Majors airport (GVT) without having to contact ATC?

• 4NM

• 4SM

• Remote PICs must contact ATC whenever within the magenta shading on Section Charts.

Answer explanation

Contact with ATC must be made when operating within Class D airport, which is indicated by the blue airport and the blue dashed line surrounding it. The radius of Class D in this case is 4NM, whic is the common standard radius, although configuration of Class D is individually tailored for some airports.

Inbound to an airport with not tower, FSS, or UNICOM in operation, a pilot should self announce on on MULTICOM frequency:

• 123.0

• 122.9

• 122.7

Answer explanation

Where there is no tower or UNICOM station on the airport, use MULTICOM frequency 122.9 for self announce procedures.

Whaat is the best way for the remote PIC to minimize the risk of radio interference during sUAS operations?

• Never transmit on aviation frequency ranges during flight operations.

• Monitor frequency use with a spectral analyzer.

• Avoid use of cellphones in teh vicinity of the control station.

Answer explanation

Remote PICs should monitor the appropriate aviation frequency such as CTAF during flight operations and make announcements concerning sUAS operations as appropriate. Some sUAS require the use of cellphone or tablet computers for operation, therefore are acceptable for use in most cases. The best way to avoid frequency interference is to check local frequency spectrum use prior to flight and continue to monitor such use during flight by utilizing a frequency spectrum analyzer.

(Refer to Figure 20, Area 3.) What is the recommended communications procedure for a landing at Currituck County Airport?

• Transmit intentions on 122.9 MHz when 10 miles out and give position reports in the traffic pattern.

• Contact Elizabeth City FSS for airport advisory service.

• Contact New Bern FSS for area traffic information.

Answer explanation

Where there i no tower, Flight Service, or UNICOM station on the airport, use MULTICOM frequency 122.9 for self-announce procedures. Such airports will be identified in teh appropriate aeronautical information publications.

When should pilots state their position on the airport when calling the tower for takeoff?

• When visibility is less than 1 mile.

• When parallel runways are in use.

• When departing form a runway intersection.

Answer explanation

Pilots should state their position on the airport when calling the tower for takeoff from a runway intersection.

As standard operational practice, all inbound and local traffic approaching or near an airport without a control tower should continuously monitor the approaching facility form a distance of

• 25 miles

• 20 miles

• 10 miles

Answer explanation

Pilots of inbound traffic should monitor and communicate as appropriate on the designated CTAF from 10 miles to landing. Pilots of departing aircraft should monitor/communicate on the appropriate frequency from startup, during taxi and until 10 miles from the airport unless the regulations or local procedures require otherwise.

Absence of the sky condition and visibility on an ATIS broadcast indicates that

• weather conditions are at or above VFR

• the sky condition is clear and visibility is unrestricted.

• the ceiling is at least 5,000 feet and visibility is 5 miles or more.

Answer explanation

The absence of a sky conditin or ceiling and/or visibilty on ATIS indicates a ceiling of 5,000 feet or above and visibility of 5 milers of more.
