System Description
Method 3
When the button with the OFF symbol is pressed for more than 8 seconds the system will
perform an unconditional shutdown. This method is recommended only in case that the
program hangs and it is not possible to shutdown with methods 1 or 2.
If you are using method 2 to switch off the system it is necessary to release the
button when you see the shutting down message. If you continue to press the off
button the main display unit may shut down by method 3.
If the request for OFF is made during flight the instrument will ask for confirmation so that
the system cannot be switched off by mistake.
It is important that the main display unit is switched off via software. Never
power down the system using the main power switch. The main display unit is
running the Linux operating system and sudden power loss may corrupt the file
system.
If main power is lost for a few seconds during flight the flight recorder will not
produce two flights. The most important flight parameter (altitude) will remain
which means that the final glide
calculations are not affected
