2.18.2 
State the occasions when TIBA (traffic information broadcasts by aircraft) might 
be introduced.


Traffic Information Broadcast by Aircraft (TIBA)

ICAO Annex 11 states that Traffic Information Broadcasts by Aircraft “are intended to permit reports and relevant supplementary information of an advisory nature to be transmitted by pilots on a designated VHF radiotelephone (RTF) frequency for the information of pilots of other aircraft in the vicinity” in the absence of ATC It notes that TIBAs “should be made only when necessary and only as a temporary measure.
TIBA will be introduced if there is a significant disruption to ATC or related service. 

If a known disruption is expected or experienced, NOTAMs action will be used to advise pilots

If TIBA is promulgated through NOTAM the frequency will be included in the advice

If more than one frequency is promulgated for that airspace use the primary frequency (found in the COM section of AIPNZ Vol 4)

AIP VOL 4 TIBA

Maintain a listening watch on the appropriate frequency for 10 minutes prior to entering a given airspace until leaving the airspace.
If leaving an aerodrome within the limits of designated airspace a listening watch should be started as soon as possible after take off.

Time Of Broadcasts

Make broadcasts 
– 10 minutes prior to entry into designated airspace
– As soon as possible before or after take off
– 10 minutes prior to crossing a reporting point
– 2-5 minutes prior to changing altitude , at the time of changing altitude and on reaching the given altitude
– At any time the pilot considers it necessary

2.16.2 Describe the checks that should be followed when becoming aware of an aircraft communication system failure


Look for  “finger trouble”

           – Electric master switch and avionics switch are On

           – VHF – COM set is ON

           – Squelch function and level

           – Circuit breakers and fuses working

           – Correct frequency selected

           – Microphone and other leads plugged in correctly

           – Surrounding terrain ( might need to fly higher)

2.14.4 Explain the procedures and phraseology involved in transmitt

2.14.4 
Explain the procedures and phraseology involved in transmitting a MAYDAY and 
PAN call with emphasis on: 
(a) Radio frequencies; 
(b) Station(s) to call; 
(c) Contents of the call; 
(d) Enforcing radio silence.

MAYDAY and PANPAN Radio Frequencies

The pilot of an aircraft in distress must transmit on the air-ground frequency in use at the time of the distress the 
distress signal MAYDAY (preferably spoken three times), followed by the distress message.
If on an unattended frequency and it is considered that better assistance can be provided by transferring 
to another frequency the pilot should do so, after broadcasting this intention on the original frequency.

Content of MAYDAY Message

The distress message should consist of as many of the following elements as possible in 

the following order:

(a) Name of station addressed (time and circumstances permitting);
(b) Identification of the aircraft;
(c) Nature of the distress condition;
(d) Intention of the pilot; and
(e) Present position, level (FL or altitude), and heading.

The transmission of an accurate aircraft position may be critical to any subsequent search and/or rescue action.

Transponder

In addition to transmitting a distress call and message, the pilot should immediately select the emergency code 7700 on the aircraft transponder. This will allow radar controllers to instantly see the aircraft’s position and altitude on a radar screen.  

Content of PAN PAN Message

This message should consist of as many of the following elements as 
possible in this order:
(a) Name of station addressed;
(b) Identification of the aircraft;
(c) Nature of the urgency condition;
(d) Intention of the pilot;
(e) Present position, level (FL or altitude), and heading; and
(f) Any other useful information.

RADIO SILENCE

After a Mayday call has been made other aircraft should impose radio silence on the frequency
unless there is no response from a ATC ground station than a pilot can try to relay the message. 

Aircraft Not involved with distress  traffic may resume making transmissions once 

The distress is cancelled or Distress traffic is terminated 
distress traffic has been moved  to a different frequency
ATS has given permission 
you required assistance yourself  ie PAN or MAYDAY   

 

Controlled Sections of most Radio Calls

They are still ….

  1. Address To
  2. Sender From
  3. Current Location
  4. Intentions (Where are you going?)
  5. Other helpful information

Now the controller will talk back to you. 

The key object is to get his or her permission the fly in their airspace.

and basic 5 part of a radio works well to help you get the permission you seek.

Unattended Sections of most Radio Calls

They are….

  2. Sender From
  3. Current Location
  4. Intentions (Where are you going?)
  5. Other helpful information

Radio call list this are only  the mandatory call.

We do a extra call as part of good airmanship…

  • Taxiing
  • Finals

2.10.2 Demonstrate proficiency in transmitting and receiving spoken

2.10.2 
Demonstrate proficiency in transmitting and receiving spoken messages 
competently and in accordance with prescribed procedures, including 
(a) language to be used; 
(b) word spelling; 
(c) transmission of numerals; 
(d) procedure words and phrases; 
(e) time system; 
(f) establishment of communications; 
(g) frequencies to be used; 
(h) identification of service; 
(i) radiotelephony aircraft callsigns; 
(j) procedures for exchange of messages; 
(k) corrections and repetition tests; 
(l) listening out; 
(m) readability scale.
When transmitting over the radio, pilots must ensure that they all use the same phraseology and terminology as well as the correct grammar laid out by ICAO. This ensures all pilots and ATC can understand each other, know what and where each other are and to ensure everyone knows each other’s intentions. 
It is important to have a sound understanding of the accepted procedures and words because they have been designed to provide clarity and efficient use of the radio.

Transceivers

The transceiver is a device onboard the aircraft which is tuned into a frequency, and used to transmit and receive radio messages on the selected frequency.

The transceiver is operated by turning the device on using the avionics switch used to power the radio, and in most aircraft the Master Switch must also be ON.

Protect your radio from voltage fluctuations on engine start up by switching it on after the engine is running.
Switch the radio off prior to engine shutdown.
