Frequency Read back reqs in Spain
 

There seems to be conflicting info between my Spanish text book and English textbook over the read back requirements of 3 decimal radio frequencies.

English text book says all 3 decimals must be pronounced.

Spanish says only first 2 decimals must be pronounced if using a VHF channel separated by 25kHz.

Where in the AIP would I find this information ?

with many thanks

Many thanks for your help, but I am a bit confused!

" In airspace where all VHF voice communications channels are separated by 25 kHz or more and the use of six digits as in 5.2.1.7.3.4.3 is not substantiated by the operational requirement determined by the appropriate authorities, the first five digits of the numerical designator should be used"

does this mean that Spain does not substantiate the use of 6 digits?

Does anybody know categorically whether or not all three decimals must be pronounced in Spain ?

Could be the Spanish text book is out of date.

really appreciate your help. :ok:

all the best
