Had a pilot (unaware of whether engineers were working on the aircraft) move the ground test switch from enable back to normal.
There were engineers working on the aircraft but his response afterwards was that there would have been no problem anyway as the flying controls would have been locked out to prevent any unwanted control surface movement.
Anyone have any info on What tests is that switch used for, is he right that there is no chance of someone potentially getting hurt?
Not unsafe at all. Annoying at most if there were software tests running at the time.
If it was safety critical, it would be tagged.
