Study Notes

Radiotelephony Alphabet & Numbers

"Hotel Bravo Juliett India Kilo" is the correct way to spell out "HB-JYC" in a radio message.
"One three thousand five hundred" is the correct way to transmit the number 13,500 to indicate an altitude or cloud height.

Radio Communication Phrases

"ROGER" means "I have received all of your last transmission."
"NEGATIVE" means "Permission not granted."
"CORRECT" means "That is correct."
"WILCO" means "I have received your message, understood it, and will comply."
"DISREGARD" means "An error has been made in this transmission."
"REQUEST" is used to indicate "I would like to know" or "I wish to obtain".

Radio Communication Procedures

Pilots shall include the word "HEAVY" immediately after their call sign in the initial call to the aerodrome control tower and the approach control unit when flying an aircraft in the heavy wake turbulence category.
A pilot can omit the ground station call sign suffix or name after satisfactory communications have been established and it is assured there will be no confusion.
An aircraft experiencing communications failure during an IFR flight in VMC should continue to fly in VMC, land at the nearest suitable aerodrome, and report its arrival.
Pilots should report "RUNWAY VACATED" to the ATC controller to indicate they are no longer occupying the active runway.

Distress & Urgency Calls

"MAYDAY" is used to signal distress.
"PAN PAN" is used to signal an urgency call.
Aircraft squawking 7700 indicates they are in distress.
The distress frequency is 121.5 kHz.
When transmitting a MAYDAY call, the frequency currently in use should be used.

Communication Procedures & Messages

Radio silence can be imposed by an aeronautical station in case of distress traffic.
Aerodrome control service is identified with the radiotelephony call sign suffix "TOWER".
Clearance delivery is identified with the radiotelephony call sign suffix "DELIVERY."
"SQUAWK 1234" means the pilot has selected code 1234 on the SSR transponder.
Flight safety messages concern the safety of an aircraft but do not require immediate assistance.
An urgency message shall be preceded by the radiotelephony urgency signal "PAN PAN" spoken three times.

Frequencies & Bands

The VHF band is from 118.0 to 136.975 MHz and has higher frequency, lower range, and higher readability than HF communications.
The minimum frequency separation between consecutive frequencies used in the VHF band is 8.33 kHz.

Other Important Terms

"CAVOK" can be used in place of visibility, weather, and cloud when:
- visibility is 10 km or more
- there is no cloud below 5000 ft AAL
- no significant weather phenomena
"SSR" stands for Secondary Surveillance Radar.
"QDM" is the Q-code for Magnetic heading to the station (no wind).
"QTE" is the Q-code for True bearing from the station.
"QUJ" is the Q-code for True heading to the station ( no wind ).
A "FRICTION COEFFICIENT 20" in a runway report means the braking action is poor.
