There's a good photo of them here; https://theaircurrent.com/aviation-safety/ai171-investigatio...

You can do them both with one hand.

Are you completely sure you can considering that they are spring loaded and they are like 7-10cm apart judging by the size of other controls?

  • I don't understand your question. I have done this myself, am I completely sure?

    • Did you mean to say you can activate the switches with one hand simultaneously? That is probably what the above commenter assumed you meant. Since lifting and twisting two switches simultaneously with one hand seems challenging.

I wonder if they could theoretically rest on top of the notch, not fully locked into either position and flip accidentally. No idea how the switches behave when not all the way up or down, but the notch looks pretty long and flat so it could be possible.

  • Something like this could maybe happen to one switch, it's unlikely but possible. But two independent switches at the same time?

Those switches are the size of a thumb. No one is moving those - separately, mind you - and not realize what is going on.

If you do them both with one hand, would they not be moved at the same instant rather than 1 second apart?
