MONITOR:

Note: The phrase “GO AHEAD” has been deleted. In its place the use of the calling aeronautical station’s call sign
followed by the ansering aeronautical stations’s call sign followed by the ansering aeronautical stations’s call
sign shall be considered the invitation to proceed with transmission by the station calling.
 Phrase Meaning
“No” or “Permission not granted” or
NEGATIVE: “That is not correct” or “Not capable”.

NEGATIVE, I SAY AGAIN: If, in checking the correctness of a read back, an operator notices incorrect items, he shall
transmit the words “NEGATIVE I SAY AGAIN” at the conclusion of the read back followed by

 Read back and acknowledgement requirements

Read Back Requirements:

The flight crew shall read back to the air traffic controller saftery-related parts of the clearances and instructions which
are transmitted by voice. Information and items not included below may be acknowledged by Aircraft call sign or by an
abbreviated read back.

QNH is always read back. Following items shall always be read-back:

a) ATC route clearance;

b) Clearances and instructions to tneter, land on, take off on, hold short of, cross taxi
and back track on any runway; and
c) Runway-in-use, altimeter settings, SSR codes, level instructions, heading and speed
instructinos and, whether issued by the controller or contained in ATIS broadcast,
transition levels.
Transfer of Communication

An aircraft will normally be advised by the appropriate aeronautical station to change from noe radio frequency to another in
accordance with agreed procedures.In the absence of such advice, the aircraft shall notify the aeronautical station before such a
change takes place. Aircraft fluying in controlled airspace must obtain permission from the controlling authority before changing
frequency.

An aircraft may be instructed to standby on a frequency when it is intended that the ATSU will initiate communications, and to
monitor a frequency on which information is being broadcast.

Test procedures including readability scale :

All radio transmissions for test pruposes shall be of the minimum duration necessary for the test and shall not continue for more
than 10 seconds. The recurrence of such transmissions shall be kept to the minimum necessary for the test.

When the tests are made, the following readability scale should be used:

Scale Readability
1 Unreadable
2 Readable now and then
3 Readable but with difficulty
4 Readable
5 Perfectly Readable
