TL position when in reverse

[TURIN]

Separately, I remember on the 727, with the engines shut down, we would sometimes check the interlock. With the thrust levers(TL's) fully aft, the reverse levers(RL's) could be selected. When the TL's were moved only slightly forward from the closed position, the RL's were mechanically blocked from being selected. Likewise, if the RL's had been selected, the TL's could not be moved forward from the fully aft position. I suppose that is different than an engine staying in reverse by itself after deselection as happened in this incident.

I believe that this is all mechanically located in the Thrust Lever unit.

I thought that was standard on all types.

I could be wrong again though.

I thought that was standard on all types.

It is, at least on Boeing.

I am hesitant to just go ahead and try this on the CF-6 engine I am operating these days.

Not sure why you'd be worried about trying it prior to engine start. It's pretty routine to do a throttle sweep prior to engine start to check for free movement (I think it might even be part of the pre-engine run checklist on the Boeing flight line) - move the throttle forward and confirm you can't move the reverse lever...

Ok. Just didn't want to be moving the reverse levers with throttle closed. Paranoia I guess.
