Ha, it is probably best if you don't fly at all since there are already many things in aviation that work just like this.

The most obvious example is the button to enable the anti-ice systems. If you don't push that button upon encountering icing conditions then you die. Of course you don't really die in either of these cases. At least not right away. Lots of other things have to go badly first.

This is why aviation relies on checklists. There are myriad things that must be turned on and off in each phase of flight, and checklists ensure that pilots don't forget.
