Steer mode set in Flight plan not consistent with steer mode on attributes page

[skypickle]

On CDU, go into FPM, enter a flight plan. hit a right line select key of any waypoint.

Here you can set the steer mode : To-From, To-To, Direct 

Change it so that it reads To-To.

 

Now go to nav page, attributes subpage.

The steer mode still says To-From.

 

This is even apparent in an old, but prob the best nav video for the A10 here:

Does To-From on the Attributes page mean something different from the WPT info in FPM?

I think I know what you're asking, but correct me if I'm wrong.  Are you asking why the NAV--> ATTRIBUTES page still says TO FROM even though the STEER PT knob on the AAP is set to FLT PLAN?

AFAIK, the NAV-->ATTRIBUTES page allows you to set the default waypoint attributes when you create a new waypoint.  The fact that is says TO FROM simply means that if you create a new waypoint, it will create the next new waypoint with the enroute steering attribute set to TO FROM.

To see or change the actual steering attribute for an existing waypoint, you have to look at the existing waypoint, like in the WP MENU-->WAYPT page.

However, when you turn the STEER PT knob to FLT PLAN, the HSI automatically goes into TO TO steering mode and overrides the existing waypoint's attributes (without changing them), so if you look at the WAYPT page, it will still show its existing attributes (TO FROM, in the case of the video above)

TL;DR -- When you turn the STEER PT knob to FLT PLAN, it is always in TO TO mode and any existing steering attributes are ignored.

There are three attributes in the A-10: default, waypoint, and flight plan waypoint. 

Default determines what attributes are for the next created. A waypoint's attributes can be different in a flight plan as not. E.g. MSNO02 can be three ways: when not in flight plan, a different way when used the first time in a flight plan, and a third way if used again in the same flight plan.

Here's a track demonstrating the independence of the attribute settings. P.S. flight plan is not limited to TO-TO or anything.

Ooof, you are correct, I forgot you can change the FP waypoint attributes in the FP menu itself

Don't listen to me, listen to @Frederf
