Actually that raises an interesting question. If you use the reverse thrust levers to actuate the speed brakes during an abort, does the speed brake lever snap back on the first movement of the reverse lever before the interlocks are released (and reverse is available) - or is it only after you get past the interlock gates.
Just to run that question again - will (say) a tiny itsy bitsy movement of the reverse levers en route to the interlocks position cause the speed brake lever to up?
Which leads on to the next part. Boeing recommend that when landing, the PNF call "Speed brakes up" or "Speed brakes not up" as appropriate.
If the captain is PF and failed to notice the speed brake lever was still down, he would presumably react on hearing the call "speed brakes not up" and pull the speed brake lever up. But would it not be quicker for the PNF to reach across and select the speed brake lever up - rather than make the "speed brake not up" bleat and hope that the captain would do something about it? At 200 feet per second of landing run, every second counts to get the weight on the wheels.
A case happened where the first officer called three times that the speed brake was not up, and after no reaction from the captain , the first officer leant across and pulled the speed brake up. This was just what the doctor ordered.
Only problem was the captain went right up him for carrying out an item out of his area of responsibility - even though it was the idiot captain that had stuffed up. There are some weirdos in the LH seat sometimes.
