Has anyone reported this problem to LXV, and if so what was their response
please? There seems to be an opportunity for a firmware fix to this
problem, not requiring any additional hardware.

In the specification for Flight Recorders, a new IGC file is not started if
power has been interrupted for less than one minute. This is to allow a
change of battery, breaker reset or change a fuse. Exactly the problem we
are discussing.

If the LX firmware were enhanced to inhibit re-calculating QNH where power
has been lost for less than n seconds, this problem goes away.

Discuss.


The LXNav manual says that the internal logger will continue to operate 'for a short time' if power is lost. The manual also says that the proper shutdown procedure should always be used, eg when changing batteries, since if power is suddenly cut the operating system may be scrambled.
