Aircraft and glider transponder codes - FAA gotcha.
I have not yet received my glider registration from the FAA (any day now, lol!), but they have assigned a transponder code for the N-number I have reserved. (see first screenshot)
To configure my avionics, I need to load this transponder code into the device.
FLARM wants it as a 24-bit hexadecimal value. (Each hexadecimal value is 4 bits in binary...so it's going to be a six-character code...but my code is not six characters.)
Hmmmm, that number the FAA gave me just doesn't seem correct.
I then called up a known, long-registered aircraft to compare their transponder code. (2nd screenshot)
Surprise! The transponder code I was given was in octal, but not labeled as such. OK, convert to hexadecimal and now everything makes sense.
Onward!
