Most of us are familiar with the concept of rebooting devices when things start to go badly, resetting your device, and allowing you hopefully be able to do whatever it was you wanted to do. It’s simple on your smartphone or computer, but an entirely different discussion when it’s something mission critical, like the software on an airplane. But the reality is that the technology on aircraft today is very much like the software on your personal devices, except a lot more robust and with a lot of additional redundancies, especially if that software is to be running on Boeing 737 Max.

More than a month after the second fatal crash of a Boeing 737 Max, the company is now one step closer to getting the Max back in service, when it completed the last test flight for updates to the flight control system that’s at the center of two crash investigations.

Boeing says that they have made the final adjustments to new 737s prior to delivery to airlines after they conducted 127 Max test flights over the last few weeks, accounting or 203 hours in the air.

Next on the list are certification flights, when Federal Aviation Administration crews will join Boeing pilots in the air to evaluate the new MCAS software and determine whether it addresses problems around the nose of the aircraft being forced down during flight.

FAA certification is necessary for the 737 Max to fly passengers again, and there’s no telling how long that could take. The agency itself is under scrutiny for a cozy relationship with Boeing when the Max was originally certified. So, the FAA has extra hurdles to leap before it can satisfy airlines and governments that the plane is safe.

I guess they remove the line in the aircraft emergency procedures checklist telling passengers that the crew is rebooting the autopilot.
