Lateral NAV/DIR TO broken on approach

[operatorjoelski]

Hello, 

Firstly, many congratulations to the ini team for delivering such wonderful aircraft to the sim. To be expected however there are some issues that I'm experiencing here. The issue is regards to the DIR function not working as intended and causing the sim to CTD (very much game breaking). What happens is when in DES mode and holding at a waypoint, using the DIR function to go to the next waypoint (1) will delete the remaining legs of the flight plan and replace it with the go around procedure (2) may lead to a CTD after a few minutes as you try frantically to re enter your waypoints (3) will stay stuck on HDG mode, DIR to any other waypoints will draw the yellow TMPY flight plan line but NAV will not engage (as it should when you DIR) 

This is game breaking for those who fly on VATSIM as if a controller were to give you radar vectors to an initial approach fix and you were to then DIR to that waypoint, you will loose your flight plan and or loose LNAV, alternatively if your asked to enter the hold at a waypoint and then DIR to the next waypoint when instructed, your flight plan disappears and your left wondering what to do next...

I will use the following as an example,

On approach for the ILS 14 Approach at Zurich via the AMIKI transition, if one does a single HOLD at AMIKI (as charted) and then DIR to ZH375 (next waypoint along) the proceeding waypoints get erased and replaced with the go around procedure for runway 14. Now, having experience with the Airbus MCDU, a quick reset can be achieved through cycling the AIRIC cycles and then INIT requesting the flight plan again, DIR to the nearest waypoint will draw the TMPY TP line however it fails to switch to NAV mode as expected (even with a clear intercept path) and the aircraft will remain stuck on HDG no matter what I do, after some time it eventually draws text over text and then the sim will freeze and CTD. 

Hopefully you will be able to replicate the above behavior but if not let me know. The reason I have put approach in the title is that I can do DIR during climb/normal level flight between waypoints no issue, its only during the descent this happens to me, my thought is that the aircraft gets confused when in a HOLD and tries to figure out a vertical descent path and then when triggering DIR to a new waypoint the logic fails to compute an appropriate path and crashes the sim (I've seen this happen with the ToLiss).

Hope to hear from you soon, in the mean time warning to fellow pilots DO NOT USE DIR or HOLD ON APPROACH!

Hi there,

Please try force re-download of the aircraft first and let me know if you continue to have the same issue. 

Thank you

Hi Eddie,

many thanks for your reply. Yes I have tried this and albeit after a very slow sim startup and a few minutes waiting for the cockpit textures to stream, during the DES phase of the flight the bug can still be replicated. Are you able to test this yourself and see if you can replicate the issue, (hold at AMIKI for one turn, with the AMIKI transition to RWY14 at LSZH on turning onto the inbound course heading, DIR to ZH375), you should see what I’m talking about right after 🙂  if not then it may be a client side issue on my part but it just seems like the MCDU logic is broken at the moment.

Understandably the majority of people won’t be using the hold/dir feature so it may not have been tested so thoroughly but for those flying on a network this might cause absolute chaos for the controllers…
 

hope to hear from you soon!
