correct as is Cannot fully delete or zero-out steerpoint

[SFJackBauer]

Somehow it is not possible to fully delete a steerpoint once its entered.

Steps to reproduce:

- Enter the F-16 on the "Ready on Ramp" mission

- Enter the STPT page (ICP 4) and scroll to the next blank steerpoint (in this case steerpoint 7)

- Enter the coordinate to Sochi (i.e. N 43.26.661 E 039.56.464 elevation 98ft)

- Note on the HSD that the steerpoint line extends correctly to the location.

- Now back to STPT page and waypoint 7, zero all the fields (i.e. set to N 00.00.000 E 000.00.000 elevation 0)

- Note on the HSD that the line now extends infinitely to some location outside of the map.

The workaround is to overwrite that ghost steerpoint with the location of the previous one, but that is obviously not an optimal solution.

Hello @SFJackBauer

I'm sorry, what is your intention here? It's not possible, by design to fully delete a steerpoint in the F-16 logic. 

Of course when you enter that value it will go to a weird location because it's outside the designed area of the Caucasus map.

Hi @Lord Vader. Thanks for replying.

The strangeness to me is that, initially, all steerpoints are zeroed out in the jet, and in a practical sense they don't exist, as in, they do not appear on the HSD or anywhere else in the avionics. However if you enter a coordinate but then later zero out the values as they were before, the state is not restored to what was before.

As the two pictures I attach here: The first one showing correctly the STPT 7 I added to the "Ready on Ramp" mission. Lets say I inputted coordinates there by mistake, even after I zero out all values, it still shows as part of the flight plan pointing somewhere 3500 miles away.

Its not about erasing the STPT 7 from the list of waypoints because, as you said correctly, that is impossible. All steerpoints from 1 to 699 "exist" in the jet, but as they have zero values they do not participate in the avionics in any shape or form.

Well, I understand what you're trying to do. However, there's no actual way to revert back to "null" input. That would be a attempt to go around the "non-deletable" steerpoints, in your mind. But "zero coordinates" actually point to here the equator and the prime meridian intersect. So, I can't really say that's accurate in that range and heading, I would have to make some calculations. But it seems reasonably directed correctly considering where the Caucasus is geographically. 

If your intent is to delete the line from view, just repeat the previous steerpoint coordinates. There's no way to "undo" a stpt creation, sorry.
