Under the photo it says: "City of Calgary" bound for Hong Kong as KL887 meets Air France 744F, F-GIUD, as AF6723 heading for Paris from Seoul".

You can see the KL 747 alright, but how can you know for certain it's KL's "City of Calgary"?. Same for AF: first: with the AF 747 you have to look very closely to see it's an AF plane, but second: how could you ever know the reg.number of the plane and where it's heading?

I was wondering the same thing. The fact that they're AF and KLM is quite clear, but the registrations are not! I guess one possibility is always that the photographer was listening with his scanner, heard their flight numbers, and then searched to see what registrations were flying those flights that day. Takes a while, but it can be done.


I guess that's what happens in the end, you start thinking about the beginning.

GSPSPOT and others

Yes there are plenty of websites dedicated to ACARS.

Google "acars".

Airband radio on 131.55 or 131.75 or whatever frequency, feed radio signal to a decoder on a computer, use software to sort it all out and display information.

It's basically a way for aircraft to automatically send out position information and to send/receive information from ops that doesn't necessarily need to go over the radio.

The AIRNAV systems sidebar on the right side of the screen is ACARS. You can buy the software and it'll display positional information on whatever aircraft are picked up. Visit the site.
