How is software installed on a new A320?

[Marc Stanford]

How is the avionics/system software installed? do they install it in the avionics bay using CDs or floppy disks?

[Christoph Sebek]

Windows Update.

Probably via data uplink I could imagine. But definitely interesting to know.

Floppies  

[Sabine Meier]

Or a usb stick on modern aircraft.

- Floopy disks on older aircrafts.

- CD and floopy on actual aircrafts via a PC connected to a dedicated plug.

[Fabrice Paulin]

I think the good old floppy disks, cd are used to update the navdata at each airac

I don’t know how the fms and other onboard software are updated: I guess they change an electronic card in the avionic bay ??

We use USB sticks for honeywell and steam machines  for universal( well the last time I did anyway)! 

[Fabrice Paulin]

you mean you use usb stick to update which software of the a320?

[Oliver Brandt]

In the AHD Helicopters we use SD Cards for mostly everything, sometimes ARINC datalink for configurations or stuff like that. Could imagine that they use similar things on the modern airliners
