Boeing reverse detents?

[TotalBeginner]

Q. Do all Boeing aircraft have two reverse detents beyond rev idle, like the 737NG?

[Cough]

787 doesn't...

747, 744, 747-8 all just have the idle “detent”, though it is really not a detent that that the levers click into. Really the interlock position.

I remember the 744 (RR engines) having a reverse idle detent and a partial reverse detent as well as a full reverse stop.
The 737-300 and -400 just had the idle detent. We were told to select about 70% N1 as an SOP which required a bit of hunting but you soon got the knack and were able to select it with some accuracy.

I remember the 737 classic 70% N1 reverse too, and then they changed the SOP to the first detent - Made life sooo much easier! (wasn't quite full reverse..)

Can someone clarify what is meant by ‘second detent reverse’? Is it the 1st detent after REV IDLE (~75% N1} or is it the max position (~82% N1)?

My FCOM does not give specific numbers. It states that the the first detent is idle reverse and the second detent provides "adequate reverse thrust for normal operations." The second detent is NOT max reverse, but the reverse lever can be moved beyond the second detent if more reverse thrust is desired. To come out of reverse, return reverse levers to the first detent, let the engines spool down to near idle, and then stow the levers.

From the B737-800 technical manual. I believe it was the same on the CL range from memory.

Yes, it's the same on the CL.
