We’re back and this time talking about Safe Operating Area also called Safe Area Operation (SAO) which is short for the combination of things that can conspire to ruin your design. We also talk about helicopters.
Why take all of this time to discuss SAO you might ask, and what is that business about helicopters? Depending on the design there may be quite a bit of tedious math involved and sometimes there is just no avoiding it. Alternatively if you can get a feel for when math is and is not critical (based on design choices), it should be easier to get your next project up and running while still obeying the rules of the road.
