Callsigns
Quick question.
How are callsigns determined?
For example in an airport the flights will have a particular code e.g. BA906, AA30 etc, but at ATCC's the callsigns are different e.g. BA906 might be BAW16MP or AA30 could be AAL6. Just wondering whether these callsigns are random or whether they are allocated depending on things such as destination perhaps...
Thanks,
