If the receiving station requires the repetition of an entire message, the operator should use the words _____________.
“SAY AGAIN”
If repetition of only a portion of a message is required, the receiving station should use the following:
- SAY AGAIN ALL BEFORE … (first word satisfactorily received); or
- SAY AGAIN … (word before missing portion) TO … (word after missing portion), or
- SAY AGAIN ALL AFTER … (last word satisfactorily received).
e.g., VANCOUVER RADIO THIS IS STINSON FOXTROT ALFA BRAVO CHARLIE SAY AGAIN ALL BEFORE “HANGAR” OVER
When transmitting a message, the radio station operator should (3 steps):
- plan the content of the message before transmitting;
- listen briefly before transmitting to avoid interference with other transmissions;
- deliver the radio message clearly and concisely using standard phraseology whenever practical.
The message handling format generally consists of four parts:
- the call indicating the addressee and the originator;
- the addressee reply;
- the message;
- the acknowledgment or ending.
How do you do a radio/signal check?
- Call another aircraft or aeronautical ground station on any appropriate frequency that will not
interfere with the normal working of other aircraft or ground stations, and request a signal check. - The signal check consists of “SIGNAL (or RADIO) CHECK 1, 2, 3, 4, 5. HOW DO YOU READ
ME? OVER.” - Your station identification (call sign) should also be transmitted during such test transmissions.
- Signal checks should not last more than 10 seconds.
How do you reply to a signal/radio check?
When replying or receiving a reply to a signal check, the following readability scale should be used:
- Bad (unreadable)
- Poor (readable now and then)
- Fair (readable but with difficulty)
- Good (readable)
- Excellent (perfectly readable)
e.g., CESSNA FOXTROT ALFA BRAVO CHARLIE THIS IS WATSON LAKE RADIO READING YOU STRENGTH FIVE OVER
What type of communications check is made from an aircraft while airborne?
Signal Check
What type of communications check is made from an aircraft prior to departure?
Preflight Check
What type of communications check is made by ground maintenance?
Maintenance Check
The first transmission of a distress call or urgency signal and message by an aircraft should be made on __________________.
the air-ground frequency in use at the time
If the aircraft is unable to establish communications on the frequency in use, the distress call or urgency signal and message should be repeated on ______________________, or any other frequency available, in an effort to establish communications with any aeronautical ground station or other aircraft station.
the aeronautical emergency frequency (121.5 MHz)
the aeronautical emergency frequency
121.5 MHz
In radiotelephony, the spoken word for distress is __________, and it should be used at ______________ of the first distress communication.
“MAYDAY”, the commencement
All stations which hear a distress call shall _______________.
immediately cease any transmission capable of interfering with distress traffic and continue to listen on the frequency used for the distress call
The control of distress traffic is the responsibility of ________________________.
the aircraft in distress or of the station which relays the distress message
These stations may, however, delegate the control of distress traffic to another station, such as an aeronautical station, which normally has a very efficient interface with air traffic control (ATC) and all search and rescue (SAR) organizations.
Distress Calls should comprise:
- the distress signal “MAYDAY” spoken three times;
- the words “THIS IS”;
- the call sign of the aircraft in distress spoken three times.
E.g., MAYDAY, MAYDAY, MAYDAY THIS IS PIPER FOXTROT X-RAY CHARLIE CHARLIE PIPER FOXTROT X-RAY CHARLIE CHARLIE PIPER FOXTROT X-RAY CHARLIE CHARLIE
The distress call shall _________________________ and acknowledgment of receipt shall ____________________.
not be addressed to a particular station, not be given before the distress message is sent
The distress message should include as many as possible of the following elements spoken distinctly
and, if possible, in the following order:
- the distress signal “MAYDAY”;
- the call sign of the station in distress (once);
- the nature of the distress condition and kind of assistance required (i.e. what has happened);
- the intentions of the person in command;
- the particulars of its position (airspeed, altitude, heading);
- the number of persons on board and injuries (if applicable);
- any other information that may facilitate rescue;
- the call sign of the station in distress.
E.g., MAYDAY PIPER FOXTROT X-RAY QUEBEC QUEBEC STRUCK BY LIGHTNING DITCHING AIRCRAFT POSITION: 20 MILES EAST OF WINNIPEG ALTITUDE: 1500 FEET AIRSPEED: 125 KNOTS HEADING: 270 DEGREES ONE PERSON ON BOARD PIPER FOXTROT X-RAY QUEBEC QUEBEC
Any station that has heard an unacknowledged distress message, and is not in a position to render assistance, shall _____________.
take all possible steps to attract the attention of other stations that are in a position to assist
When a distress message is received and it is known that the aircraft is not in the immediate vicinity, _____________.
sufficient time should be allowed before the distress message is acknowledged. This will permit stations nearer to the station in distress to reply.
Action by Other Stations Hearing a Distress Message
- Continue to monitor the frequency on which the distress message was received and, if possible, establish a continuous watch on appropriate distress and emergency frequencies.
- Notify any station with direction-finding or radar facilities and request assistance, unless it is known that this action has been, or will be, taken by the station acknowledging receipt of the distress message.
- Cease all transmissions that may interfere with the distress traffic.
In distress traffic, the distress signal __________, spoken once, shall precede all transmissions.
“MAYDAY”
This procedure is intended to alert stations not aware of the initial distress call and now monitoring the
distress channel that traffic heard relates to a distress situation.
The acknowledgment of receipt of a distress message shall be given in the following form:
- the distress signal “MAYDAY”;
- the call sign of the station in distress (spoken three times);
- the words “THIS IS”;
- the call sign of the station acknowledging receipt (spoken three times);
- the words “RECEIVED MAYDAY”.
e.g., MAYDAY PIPER FOXTROT X-RAY QUEBEC QUEBEC PIPER FOXTROT X-RAY QUEBEC QUEBEC PIPER FOXTROT X-RAY QUEBEC QUEBEC THIS IS WINNIPEG TOWER WINNIPEG TOWER WINNIPEG TOWER RECEIVED MAYDAY
A distress message repeated by a station other than the station in distress shall transmit a signal
comprising:

- the words “THIS IS”;
- the call sign of the station relaying the message (spoken three times);
- the distress signal “MAYDAY” (once);
- the particulars of the station in distress such as its location, nature of distress, number of persons on
board, etc.
E.g., MAYDAY RELAY, MAYDAY RELAY, MAYDAY RELAY THIS IS CESSNA NOVEMBER JULIETT INDIA CESSNA NOVEMBER JULIETT INDIA CESSNA NOVEMBER JULIETT INDIA MAYDAY PIPER FOXTROT X-RAY QUEBEC QUEBEC STRUCK BY LIGHTNING DITCHING AIRCRAFT POSITION: 20 MILES EAST OF WINNIPEG ALTITUDE: 1500 FEET AIRSPEED: 125 KNOTS HEADING: 270 DEGREES ONE PERSON ON BOARD PIPER FOXTROT X-RAY QUEBEC QUEBEC
Imposition of Silence
The station in distress, or the station in control, shall use the expression _______________.

Imposition of Silence
If it is believed to be essential, other stations near the station in distress may also impose silence during a
distress situation by use the international expression ______________.
If it is believed to be essential, other stations near the station in distress may also impose silence during a
distress situation by use the international expression “SEELONCE DISTRESS”.
When a station is no longer in distress, or when it is no longer necessary to observe radio silence (i.e. the
rescue operation has concluded), the station that controlled the distress traffic shall transmit a message
addressed to “ALL STATIONS” on the distress frequency(ies) used, advising that normal working may
resume. The proper procedure for cancelling a distress message is:
- the distress signal “MAYDAY” (once);
- the words “HELLO ALL STATIONS” (three times);
- the words “THIS IS”;
- the call sign of the station transmitting the message;
- the filing time of the message;
- the call sign of the station in distress (once);
- the words “SEELONCE FEENEE”;
e.g., MAYDAY HELLO ALL STATIONS, HELLO ALL STATIONS, HELLO ALL STATIONS THIS IS WINNIPEG TOWER TIME 1630 ZULU PIPER FOXTROT X-RAY QUEBEC QUEBEC SEELONCE FEENEE OUT
The urgency signal is ____________ spoken three times. It should be used at the beginning of the first
urgency communication.
“PAN PAN”
Stations that hear the urgency signal shall continue to listen for __________ on the frequency which the signal was heard.
at least three minutes
After that, if no urgency message has been heard, an aeronautical ground station should, if possible, be notified of the receipt of the urgency signal and normal working may be resumed.
The urgency message should contain as many of the following elements as required, spoken distinctly
and, if possible, in the following order:
- the urgency signal “PAN PAN” (three times);
- the name of the station addressed or the words “ALL STATIONS” (three times);
