FMC & SLOP
In my experince when I was flying I would enter 0 and that would return me back to track.
That being said it is like golf 100 yards to the green a wedge or a 9 iron.

Generally speaking, when an offset is deleted, the FMS navigation guidance should command an appropriate heading to re-intercept the original course at 45 degrees.
Consult your various FMCS User Guide for more accurate information.

Who cares, big picture stuff really.
It doesn't really matter what the parameters are you should be in control and watching what it does.......if you don't like what you see then go selected.....

My Boeing turns to re-intercept the original route "at up to 45°".

My company actually doesn't want us to go out of LNAV if you're doing oceanic nav.

Thanks for all the informative replies...
As many of you know, I design RNP procedures. What I am looking at is a single RNP track, but with offset approaches for wake turbulence separation. The standard would be to have completely separate procedures, but then ATC has to track many more waypoints, so I am working up this concept...
While I did find significant verbiage on engaging the offset, there was little in the way of parameters when removing the offset. Horizontal return is somewhat detailed, but in actual operation, 'up to' can be very different.
In addition, and to be more specific, if the AC is on descent, will the FMC allow the removal of the offset while on auto?
Thanks in advance.

The Honeywell FMS as fitted to Ejets does not allow the use of offset when on published procedures. It will cancel any when approaching the first waypont of the procedure so to include the use of automatic offset in a procedure may prove troublesome ;-)

I believe on the 737, the offset will end at the FAF unless you specify an earlier waypoint. You can also cancel the offset or just go direct to the next waypoint, which cancels any subsequent offset.
