737NG RX-xx Point
Hi folks,
A new FO was asking me recently if it is possible to make a user defined waypoint based off an RX-xx point to aid descent planning during a visual approach. e.g. making a base leg to the RX-xx point.
I tried but was unable to do this. The best I could manage was to make a waypoint 4NM back from the RW-xx point followed by a base leg.
Is there actually any way of making user defined waypoints from a RX-xx point and if not why would this be the case?
It seems logical to me that this function should be available and our company SOP is to use the RX function for visual approaches when no FMC approach procedure is available.

Not sure if this is what you are asking. Aplogies if its not
Select Rwy and and suitable Rwy extension (say 3.1Nm) and 3 degree path.
Execute.
Join the dots.
Then Input a new point inside the Rwy ext (say Rwy Ext/ - 0.1)
New point is created.
Execute
Now you can delete/overwrite the original Rwy ext (it has done its job).
The new point at 3.0 nm is now a lot more friendler and can be used to build a base leg off.
Full circuits can be 'built' but its a lot more fun to **** it up yourself.

Firstly, thanks for taking enough of an interest in your FO's development to come here and ask.
Might I suggest though, that instead of providing him/her with a crutch to use, you allow the person to do it visually. It can be challenging, as sims aren't really good at visual manoeuvrers, but I think in the long term, your FO will look back and thank Captain JT8D for teaching him how to do a visual approach. It's ok to mess it up a few times, too. We debrief and have another go next sector.

Thanks everyone for the replies.
Basically anytime we tried to use the RX point to make a point based off it we got the INVALID ENTRY message on the scratchpad. The best we could manage was use the RW-xx point itself and make a point 4nm back from the runway(RW-xx/-4.0).
I really would love to do this but unfortunately this is forbidden in my company hence why I personally do not bother with visuals anymore. This also explains my associated lack of knowledge of the RX point! SOP is full use of AFDS on visuals down to MUH if desired.

Just to confirm that you do not build anything off the runway extension point.
The 3.1 Nm Runway extension is merely to define the track emanting from the runway.
Once the new point is created at 3.0 Nm (on the defined track from the runway) then the Runway Extension at 3.1 is deleted/overwritten.
Then the new user defined point (3.0Nm) can then be 'built' off.
Our mob tends to frown on them as well but knowing how to manipulate the FMC is valuable.
Let me know if you have problems as I can send you a couple of screen shots.
