Hello guys!
I'm listening to Atlanta Macey (Northeast Approach) ATC and viewing the radar map with aircrafts and flight data.... Next to the flight level of a few flight is located a 'C' ... for example:
DAL1819
FL207C 415 (415 is the speed, right?)
CLT ATL
MD80

Climbing?? FL 207 seems like the plane would be in a climb. Maybe there is a "D" for descending.

No, actually from my experience with Flight Explorer (another subscription flight tracking program), the C means that the aircraft is currently at a "Mode C" altitude. Unfortunately I don't know what a mode C altitude is, so I guess that really doesn't help you.

Mode C means that the transponder shows the altitude of the aircraft.
Altitude encoding.

No, it cannot be the 'climb' sign because next to the 'C' there is a arrow up or down - for climbing or descending.
Thanks for your 2nd reply!

No - I'm in Europe - Innsbruck (INN) Just go to http://www.atcbox.com and on the right side there must be a link to Atlanta Macey Arrival.
Press the link and you'll get to the ATC site - transmission will start automatically - To watch the screen - Press the SCREEN link beneath the radio. The map will reload every 40 seconds or something like this...
Oh, and ATL airport is in on the lower end of the map - located in the middle - it can be difficult to find the airport during rush hour with lots of planes...
