ATIS
Can anybody shed some light on what the frist number represents at the begining of an ATIS transmission, the number today for the Edinburgh transmission is an 8 which precedes 16 which is the date.
Just not sure what the eight is?, cant represent the number of hours because it is for 24 hours according to the times given in the transmission.
e.g forecast 8 16 time 12 hours to 8 17 time 12 hours 060/15
Any ideas anyone?
