Agreed. Not for avionics, but I cannot overstate how much of an improvement the Gotek/Lotharek/various other Floppy Disk/scsi to SD solutions are over finding NOS/still working storage media from that era. Ive a couple of old samplers from Emu and Ensoniq that I can continue using and not worrying (as much) about data loss and storage.

It wouldn't necessarily be a certification issue because updates to avionics bundles already require a checksumming/validation step. At worst, if it doesn't work you'd have to try again. However, adding in the USB support on some of these older devices might be a hassle.

We really should be updating our planes from S3 and running the entire fleet on Kubernetes with Kafka to handle all the Airline tickets and Redis to make it all go fast.

There are data loaders in the avionics world that use emulators, including ones which emulate floppies to load off floppy images.
