CDU-Markpoint-question

[Wali763]

Hi.

Probably a problem, that does not touch many people. Still I cant figure this out for myself.

In short:

Making a new Markpoint blocks the way back to the previously set WP-page on the CDU. I only have a workaround, that seems odd. Anyone know the correct procedere?

Or is this just a bug.

 

Long:

Usually for a mission I prepare a new waypoint, so I only need to push in the UTM-coordinates and be able to use the WP.

But when creating a Markpoint, the CDU jumps to the markpoint-page and I dont seem to be able to go back to the last WP-page to further edit my prepared WP. Pushing "prev" wont do it.

I can set the AAP-SteerPt-switch to "other" (not Mark) and then I can circle the Markpoints (like I were on Mark on the AAP-SteerPt-switch) but not the rest of the WPs. Even going to some other page in the CDU and then pushing the "WP"-button will bring me back to the Markpoint-page.

The only way out for me right now is to create a new WP, then I can circle the previous ones too. But then I do have to edit the new created WP or circle back to the previously.

"My" procedere of going back to the last WP seems odd and wrong to me. Anyone know the correct way?? 

Thx.

UFC: FUNC + 3 -> Waypoints  and enter your WP name or number to call up your waypoiny

or FUNC + 9 (selects mission points), and cycle with STEER to your waypoints

[Yurgon]

To elaborate a little further, the AAP STEER PT dial selects the type of points that you can cycle between FLT PLAN (points in your currently selected flight plan), MARK (all mark points) and MISSION (all waypoints, initial points and airports stored in the aircraft's database, regardless if they're part of the flight plan or not).

This dial can only be set by the pilot, but when you create a markpoint, it's as if the jet conveniently set it to the MARK position for you in the background. In order to get back to flight plan points or mission points, cycle the dial to any position and set it back to the position you want.

What Stuka describes with FUNC + 9 on the UFC is just another way to switch between these 3 databases:

• UFC FUNC + UFC 7: Flight Plan database
• UFC FUNC + UFC 8: Markpoint database
• UFC FUNC + UFC 9: Mission point database

So that's just another way to achieve the same objective, and again this does not change the position of the AAP STEER PT dial down below the CDU, but it's exactly the same as if you rotated that dial.

That's good thinking.

If you happen to create a markpoint and then you want to get back to your new waypoint, just cycle the AAP STEER PT dial back to MISSION, or set UFC FUNC + UFC 9, then get back to the waypoint page with UFC FUNC + UFC 3 and in the CDU select WAYPOINT at LSK R1, and you should be right back at your previously created new mission point.

This probably sounds ridiculously complicated, but with a bit of practice, it's actually a pretty fast process.

Plus, if you create a markpoint in the meantime, there's probably a very good reason to do so and you'll probably want to focus your attention on that markpoint, so the jet switching to the markpoint database in this scenario actually makes sense IMO.

Oh I skipped this part. That's also good advice! In the WP page in the CDU, you can always call up the waypoint you're interested in, even if the jet has set the MARK or FLT PLAN database. Like Stuka says, just type the waypoint number or name and hit the appropriate data entry field in the CDU.

Big Thank you for your elaborate answers!!! They really helped me s lot, also in understanding. Thx

The markpoint shows up in the waypoint page. So just press the number of the waypoint you want and then press the top left LSK should jump back to it
