  1. Today is a very special day over here - it's #Gracie's 6th Gotcha Day

    On this day in 2020, we brought this beautiful grrrl home from Benson animal shelter and she changed our lives in all the best possible ways.

  8. 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!
