Getting a Badge Candidate set up with barograph is a task no one seems
eager to undertake. *Then there are the periodic calibrations required
and the interpretation of the trace. *The width of the line seems
important some times. *Does anyone know if the LXNAV Nano will require
periodic calibrations for badge use?

yes all flight recorders require calibration. Barographs must be
calibrated within the preceding year, Electronic Flight Recorders must
be calibrated within the preceding 2 years. If a badge leg is claimed
with either type of recorder out of calibration you have one month to
get it calibrated and submit the data.

there is still setup required for the flight recorder. for the
barograph the OO has to fix the paper to the drum, mark the paper, put
the drum in the barograph and probably scribe a baseline and maybe
make a timing mark. then of course wind the barograph and turn it on.

for the flight recorder they'll have to connect it to their computer,
make sure the pilots name, glider, glider N number and whatever else
is required for the electronic declaration. Since you'll be using
this for renters this will have to be done basically before each
flight. One benefit us private owners have is we can usually set up
the device when we get it and if we always fly the same glider never
worry about it. Having the wrong info in the electronic declaration
risks invalidating the flight, unless a paper declaration is made
after the electronic one. I am paranoid enough about the electronic
flight recorder that I always make a paper declaration just to be
safe.
