I would like to tune into this thread, as I also have a problem with the lateral flight of an RNAV approach if I have previously been guided by vectors through ATC. Ultimately, I will not fly off the complete STAR / Approach Transition, but will be guided by ATC from any point on more or less frequent directional guidelines for intercept the Final Approach course.
So I'm flying with LNAV, I've also armed the approach before, I get directions from ATC and break out of preprogrammed routing. The remaining navigation points up to CF / IF are no longer served.
At some point the final direction is given to intercept the final approach course. Now I have understood that by means of the ACT APP I remove all remaining navigation points between my position and the CF / IF, at the same time the approach baseline is extended by 50 NM to give me and the FMS a reference to intercept the final approach course , At the same time I enter on the NAV Page the last direction of ATC, or confirm this, since the current HDG should be adopted. As I approach the approach baseline, the aircraft intercepted the final approach.
Unfortunately that does not work in the Dash 8 by Majestics. First I have to cancel LNAV HDG, then I can activate the Approach (ACT APP). before I get ACT APP displayed, but it does not respond. If I fly on, the plane overflies the approach baseline and refuses to intercept the final approach course. Is it on the non-actuated INTC prompt on the NAV page?
The next time I pressed it enough, but what does the Dash do, it immediately turns away from the assigned HDG to read the Final Approach at an angle of 60 °, as we read in the manuals, but this is not intended , the ATC said something else.
I have tried everything several times in different combinations, but I'm not really smart.
In the Majestics Forum, I have also started a post, but also not really helpful answers.
Unfortunately the Airline2 video is only limited to the complete flying after the given routing. I do not have a problem with that.
