bpcw001 28 Posted January 12, 2016 Share Posted January 12, 2016 Hi, take any flight plan and add a STAR. Make sure to select a STAR has ALT constraints. Now, switch to PLAN mode and step through the flight plan until you reach the STAR waypoint(s) that have an ALT constraint and the waypoint(s) is/are displayed on the ND in plan view. In the MCDU, delete an ALT constraint for such a waypoint and observe that the constraint displayed on the ND does not get deleted. Only when navigating back and forth in the flightplan, the next time you come across the respective waypoint, the ALT constraint on the ND will be gone (in PLN mode). I would have expected an instant update of the ND display whenever you modify/add/delete a constraint at a waypoint in the MCDU. It may not only happen with STAR waypoints, but with DP and enroute waypoints as well, but I did not test that. Is that a bug or an issue with my installation or is it supposed to work like this? Thanks for looking into it. Link to comment Share on other sites More sharing options...
Emi 5161 Posted January 17, 2016 Share Posted January 17, 2016 Good evening, I'll need to try this one. So far I never noticed this since Airbus does not allow pilots to modify constraints. Therefore this is something you'd probably never see in real life. Link to comment Share on other sites More sharing options...
Deputy Sheriffs The Dude 6537 Posted January 19, 2016 Deputy Sheriffs Share Posted January 19, 2016 It is indirectly a bug. The ND PLAN mode most probably does not update when it is "active". I will forward it to the bug tracker we use. In RL Airbus pilots can modify these constraints btw but like Emi said it is technically not allowed for STARs and approaches due to the integrity of the FMS database.

bpcw001 28 Posted January 20, 2016 Author Share Posted January 20, 2016 Thanks for looking into this. Maybe I did not get this right, so please correct me: In the real Airbus, all contraints can be modified in the MCDU (technically), but pilots are not allowed to do so for STARs and approaches (procedural restriction) ? At least the modification of constraints should work (including ND update in all modes) for all those cases where this is technically allowed in the real-world as well. There should not be an "enforcing" of a procedure by disabling some feature technically if it is not technically disabled in RW as well. Link to comment Share on other sites More sharing options...
