[ACARS] Alphanumeric Callsigns

Fri, 17 Oct 2003 14:13:22 +0300

Hi
and OK. For a moment I thought that they would not have been flight numbers.
I know that in Finland Finnair is regularly using Alphanumeric call signs 
where the last "digit" is a letter.
Like "Finnair 834 P".
Finnair also use them in ACARS and it makes it more challenging to keep the 
routing record up to date: As soon as you have added another entry, say 
834P, then after a couple of days they use 834X and a new entry is needed...

I have been wondering that what is the logic behind these additional "letter 
digits" but maybe there is no other logic but the one you, Barry, stated 
below.
