But what to do in that first second just after you recognise that you have a problem?
On my last type, a factory pilot told me that the manufacturer designed it in such a way, that if you just put the N1 needles at 12 O'clock, you'll neither go too fast or too slow to get in trouble.
This was on an Embraer, but is there a similar 'rough guide' for the Boeing?
For a UAS, you would do the UAS memory items, which include a pitch attitude and an N1, as pointed out by Derfred in his post above.
