Hi,

Every now and then I have the problem that my flight plan and waypoints are deleted as soon as I take off.

I recorded a video about it... You have to look at the navigation display... where you can still see the route... and then suddenly it disappears.

I've had this problem a few times with Fenix... That's why I copy my flight plan in Sec FLP before the flight...

But this is annoying and I don't understand why the problem still exists despite updates.

It happens exactly at 09:21

Post it on their Discord website.

 

Fixed it for ya.

What are we supposed to be looking at? I didn't see anything happen at 09:21.

It is really hard to tell with the zoom level, but it looks like the ADIRS haven't aligned yet.

That's the only thing I noticed as well. I watched up until that point, and I didn't see him turn them on, but it does eventually align. I think the tug lifted the airplane before it did, though. Not sure if that would cause the problem.

When he switches back to cockpit view on the runway, he clearly has a flight plan active on the ND. What I did notice is that at ~21:00 he appears to connect and disconnect the AP 2 or 3 times. I can't read the panel, but I did see a red message in a box on the ECAMS and the light on the AP button flashed a couple of times.With the zoom level, I can't tell what modes the AP  did activate when it switched on, but I don't think it was the normal managed nav and climb modes. I don't think your flight plan got "lost', I think you got open climb and heading hold, which made the plane fly straight instead of turning to the next waypoint. After that, the airplane didn't know what he was doing, so it gave up and just set the flight path as a straight line in the direction he was going. I also noticed that he never moved the throttle from Flex back to climb.

@Lenovouser - Re-fly this flight, but instead of engaging the AP using whatever control you did on this flight, use the cursor to physically hit the AP button on the console (just once). I think you might have a control binding issue that is sending the command more than once and it is confusing the airplane. Oh, and remember to reduce the throttle to the "Climb" position as soon as the flashing message on the ND tells you to do so. You'll overspeed as soon as you stop climbing if you don't. When you scrolled through the flight plan at the end, it was still in there. If you had hit the "Dir" button and selected DF626 (I think), I think you might have been able to resume your flight.

The reason why it deleted is because it thought you was going around since you went to toga instead of thr clb may need to calibrate thrust lever positions correctly. Real aircraft does this.

My guess is user error

I have posted about this before as well. It happens to me made once every 50 flights. it is not a TOGA issue as I use TOGA to take off every flight. It is fine if it is "user error" but what is it we are doing wrong?

To be fair the displays are so blurry it's hard to make out, If you can reproduce it may be helpful to redo with it zoomed in to the displays so things can be read.

It does look like it goes into TOGA as the flightplan disappears, but can't be 100%.....

The video shows Flex for departure. Then when it told them to go clb thrust they went to toga which makes the aircraft think you are in go around mode hence the deletion. Maybe show a video from a toga departure and we can see what is going on or submit a ticket.

Lehbird isn't the OP. Lenoveruser is.

As stated above, that is not my video, however, with the information provided here, maybe you all can help at least me if not others. Perhaps it is not the correct procedure, but EVERY takeoff I perform I go TOGA and stay at TOGA until told to reduce to climb. As I said, this works for me 98% of the time. Is there something inadvertently I could be doing adjusting the throttles that would lead to the deletion?
