GM1 SERA.14035(a)(6) Transmission of numbers in radiotelephony

Q: What is a caution to consider when transmitting VHF radiotelephony channels with six digits in 25 kHz separated airspace?

Caution must be exercised when using all six digits because aircraft installations with a channel separation capability of 25 kHz or more may only allow selection of the first five digits on the radio management panel.

ED Decision 2016/023/R

TRANSMISSION OF NUMBERS FOR RADIOTELEPHONY CHANNEL FREQUENCIES

(a) The following examples illustrate the application of the procedure.

Channel	Transmitted as
118.000	ONE ONE EIGHT DECIMAL ZERO
118.005	ONE ONE EIGHT DECIMAL ZERO ZERO FIVE
118.010	ONE ONE EIGHT DECIMAL ZERO ONE ZERO
118.025	ONE ONE EIGHT DECIMAL ZERO TWO FIVE
118.050	ONE ONE EIGHT DECIMAL ZERO FIVE ZERO
118.100	ONE ONE EIGHT DECIMAL ONE

(b) Caution must be exercised with respect to the indication of transmitting channels in VHF radiotelephony communications when all six digits of the numerical designator are used in airspace where communication channels are separated by 25 kHz, because on aircraft installations with a channel separation capability of 25 kHz or more, it is only possible to select the first five digits of the numerical designator on the radio management panel.
