Boeing 787s must be turned off and on every 51 days to prevent 'misleading
data' being shown to pilots

The US Federal Aviation Administration has ordered Boeing 787 operators to
switch their aircraft off and on every 51 days to prevent what it called "
several potentially catastrophic failure scenarios" – including the
crashing of onboard network switches.
The airworthiness directive, due to be enforced from later this month,
orders airlines to power-cycle their B787s before the aircraft reaches the
specified days of continuous power-on operation.
