|184.108.40.206.1 Transmission of numbers
|220.127.116.11.1.1 All numbers, except as prescribed in 18.104.22.168.1.2, shall be transmitted by pronouncing each digit separately.Note.
The following examples illustrate the application of this procedure (see 22.214.171.124.3.1 for pronunciation).
|aircraft call signs
|Air China two three eight
|Olympic two four two
|flight level one eight zero
|flight level two zero zero
|heading one zero zero
|heading zero eight zero
|wind direction and speed
|200 degrees 70 knots
|wind two zero zero degrees seven zero knots
|160 degrees 18 knots gusting 30 knots
|wind one six zero degrees one eight knots gusting three zero knots
|squawk two four zero zero
|squawk four two zero three
|runway two seven
|runway three zero
|QNH one zero one zero
|QNH one zero zero zero
|126.96.36.199.1.2 All numbers used in the transmission of altitude, cloud height, visibility and runway visual range (RVR) information, which contain whole hundreds and whole thousands, shall be transmitted by pronouncing each digit in the number of hundreds or thousands followed by the word HUNDRED or THOUSAND as appropriate. Combinations of thousands and whole hundreds shall be transmitted by pronouncing each digit in the number of thousands followed by the word THOUSAND followed by the number of hundreds followed by the word HUNDRED.Note.
The following examples illustrate the application of this procedure. See
188.8.131.52.3.1 (Pronunciation of numbers)
|three thousand four hundred
|one two thousand
|two thousand two hundred
|four thousand three hundred
|visibility one thousand
|visibility seven hundred
|runway visual range
|RVR six hundred
|RVR one thousand
|184.108.40.206.1.3 Numbers containing a decimal point shall be transmitted as prescribed in 220.127.116.11.1.1 with the decimal point in appropriate sequence being indicated by the word DECIMAL.Note 1.
The following examples illustrate the application of this procedure:
|ONE ZERO ZERO DECIMAL THREE
|THREE EIGHT ONE FOUR THREE DECIMAL NINE
For identification of VHF frequencies the number of digits used after the decimal point are determined on the basis of the channel spacing (
refers to frequencies separated by 25 kHz,
refers to frequencies separated by 8.33 kHz).
The channelling/frequency pairing relationship for 8.33 kHz and 25 kHz is found in Table 4-1 (bis), Volume V.
|18.104.22.168.1.4 PANS. When transmitting time, only the minutes of the hour should normally be required. Each digit should be pronounced separately. However, the hour should be included when any possibility of confusion is likely to result.Note.
The following example illustrates the application of this procedure when applying the provisions of 22.214.171.124.2:
|0920 (9:20 A.M.)
|TOO ZE-RO or
ZE-RO NIN-er TOO ZE-RO
|1643 (4:43 P.M.)
|FOW-er TREE or
WUN SIX FOW-er TREE
