Radio Communication Flashcards
How are altitudes stated?
Say separate digits of thousands, then digits of hundreds. For example, 14,500 is stated “One four thousand five hundred”. For 18,000 feet and higher, 1 flight level equals 100 feet. So, 27,500 is stated “flight level two seven five”.
How are bearings, courses, headings, and wind direction stated?
These are always stated in a 3-digit format. For example, 50° is stated “zero five zero”.
How are radio frequencies stated?
Say each individual number, including the decimal point stated as “point”. 128.25 is stated: “one two eight point two five”.
How are altimeter settings stated?
Say each individual number, excluding the decimal point. For example, 29.96 is stated: “two niner niner six”.
How are location identifiers stated?
Say each number and/or phonetic alphabet word separately. For example, W29 is stated: “whiskey two niner”.
How are transponder codes stated?
Say each digit separately.
How do you verify that you have landing clearance?
Say “Verify clearance for Cessna 201TH”.
How often are AFDs updated?
Every 56 days.
On sectional charts, what color is used for frequencies at controlled airports? Non-controlled?
Blue for controlled airports, magenta for non-controlled.
On sectional charts, where are frequencies for Flight Service Stations?
Above the heavy- or thin-lined communications box for each VOR shown on the chart.
What does the “R” next to a FSS frequency on a sectional chart mean?
It means that FSS will receive transmissions on that frequency. They will transmit over the VOR frequency. If there is no “R”, the frequency can be used for both transmitting and receiving.
What frequency is used as the CTAF at airports without a tower, a FSS station, or a UNICOM?
The MULTICOM frequency: 122.9.
How is the CTAF frequency indicated on a sectional chart?
By a white “C” within a magenta or blue circle, in the airport data block.
What’s the difference between CTAF and UNICOM?
CTAF is for air-to-air communications. UNICOM is a privately-operated air-to-ground frequency that can be used to request ground services.
Where are UNICOM frequencies listed on sectional charts?
In bold type, after the elevation and runway length entries.
How often are AWOS and ASOS reports updated?
Every minute.
Where can AWOS and ASOS reports be received?
At or above 3,000 AGL, or within 25 nautical miles of an airport.
Where are control tower frequencies located on sectional charts?
In the airport data block, following the letters “CT”.
What frequencies are ground frequencies generally between?
121.6 and 121.9.
