They probably want to change their batteries every once in a while, as well.

It wouldn’t have been to the open internet but to the company’s intra-net.
PS: it’s up to maintenance to ensure of the upgrades. When we fire up the system it had better be the latest version; this is Airbus. I don’t know how Boeing does it.
“Ok it is Linux.”
So, you only heard of Linux so everything is Linux?? VxWorks is NOT linux.

Ah, ok. IMHO whatever it is, it needs to be secure with no access from the general internet, and there needs to be an orderly system in place so that others such as pilots and mechanics can work with some assurance about what they are working with.
That's a really good point. I'm sure it's costly in terms of time, at least.
Ok, thanks anyway, and I appreciate your thoughtful answer.
Agreed. Have to submit a change, maybe even go to CAB... bleh just to upgrade Cisco ios on a couple stacks.
You know why? It saves a couple of pennies per car not to use any flash memory for it. Same reason they don’t put spare fuses or fuse puller in cars anymore. Every design goes through reviews for cost not benefit.
I hated working automotive but it did teach me lots about cost trades.
Learn something new every day!
The windows ARE pretty cool on a 787. I only hope they don’t have to open and close them on a recycling period that lines up when I’m sitting next to them at 38,000 feet
I don’t have auto-updates turned on. I would imagine any updates are done manually, with someone updating the firmware on board.
Software updates are performed on Boeing and Airbus aircraft frequently. Navigation databases are updated to the flight control computers every 30 days. This is usually accomplished with a portable computer taken on board the aircraft and connected to a data port in the cockpit. 787’s and A350’s have the ability to receive software over wifi. That data is then downloaded by a mechanic from the inbox or repository to the destination hardware. This is done in the flight deck. A mechanic has to verify that the software is the latest and then install it to the particular destination. It cannot be accomplished remotely. Boeing isn’t the only aircraft that require power to be cycled on and off routinely. Airbus 330’s and 350’s do also.
My mistake, nav databases are loaded to the flight management computers, not flight control computers. As for cycling aircraft power, 20 minutes off before restarting is typical.

I did not want to go into details because I was not certain, but thanks for filling in those details. I would imagine that what you described is very secure.
How many pilots keep their 787 idling 51days?
It’s a big deal to completely shut down a modern aircraft and then power it all back up. And economically speaking, the airline wants that plane in the air carrying passengers as much as possible. So it’s not idling any more than necessary, and it’s not getting power cycled unless absolutely necessary.
