Hi there, somehow I can’t get those 2 waypoints part of my UN741 airway.

They do appear on Navigraph but on the latest AIRAC (using the Headwind A339X) it says “WAYPOINT MISMATCH” which means the FMS cannot detect those 2 waypoints as part of the UN741 airway

Might be my mistake, but maybe something worth to check …

They are indeed located on UN741, cannot vouch for the Headwind data hoewever:

Just as info:  
The airways are not working correctly in the default MSFS data format. The reason is, that there are a lot of information which are missing and which we can’t add due the missing fields.

Cheers
