Ground Operations ? Heathrow

[reheat101]

Afternoon All,

I've been picking up a few mode s codes from London Heathrow, i'm guessing they are ground ops ?

Mode s codes
424A64 (ASD)
424A62 (ASD)

i must have more in the database, Does anyone have any databases on the ops ? Reg's etc.

Any help would be great,

Regards,

Lee.
