Problems with FMS - Direct To - WPT

[aerostar]

First off, I don't know how to write read XML code, I am interested in it though but feel its too complicated for me.

Therefore I'm writing here for some info / help if possible...

Problem is that I am very frustrated by some aircraft I have that will not fly direct to a waypoint when using a FMS flightplan, they will fly to intercept the leg that the waypoint is on though.

I have been told that this is a limitation of FSX/P3D and Navigraph and the alternative deletes the full flightplan. I don't understand this as some aircraft CAN do it such as the PMDG's and the F1 Mustang etc..

I'm wondering if , while in a Flightplan and you want to go 'direct to' a wpt - when you press the FMC button to select the wpt - the code takes the aircraft present position and makes this a wpt called DCT then updates the Flightplan with the new wpt, this will make a new LEG in the flight plan from present position and then the plane can follow this LEG direct from present position 'DCT' to waypoint selected.

Is this possible.... ?
Thanks

Well, that's a simplistic way of seeing it... yes.

However, the aircraft you see the intercept behavior in...(non-PMDG)... they're using the default GPS flight plan interface. Custom aircraft like Eaglesoft's Citation X v2 and PMDG aircraft... they don't use the default GPS flight plan at all.

Hi

This is not a limitation of FSX .

I have in my ' Mission Adaptive Flight Plan Editor ' created in xml , buttons that allow a 'Saved Flight Plan' to be modified by addition or deletion of Waypoints ,
or if desired the creation of a whole Flight plan from scratch .

So then you have and are flying your flight plan , that flight plan will be showing up in my flight plan list page ,
now at any stage you might wish to create a DTO ( Direct To ) , you enter where you want that DTO Waypoint to be , then activate the DTO .
your aircraft now turns and flies to the DTO Waypoint , In the Flight Plan listing page , the original flight plan has disappeared and been replaced
with the DTO ( Direct To ) .
Now at any stage I can hit the "Revert button" ( which happens to be - Cancel Direct To ) , the DTO is cancelled and replaced with the
original Flight plan , and the aircraft turns to fly that original flight plan , and the Flight plan list shows the original in full again .

The "Revert Button" code that I use is ,

             if{ 0 (>@c:FlightPlanWaypointIndex)
                           0 (>@c:FlightPlanCancelDirectTo)

I can do as many different Direct To's as I wish in a flight as I desire , however , after each DTO you MUST revert back to the flight plan .
So the sequence is ,
FP - DTO - FP - DTO - FP -DTO - FP .......... you must end on a FP (Flight Plan)

If you do the following ,
FP - DTO - DTO , then the revert is back to the previous DTO and you have lost access to your original FP (Flight Plan) .

As WarpD indicated it's all a matter of how the instrument is written by the Developer .

Cheers

Thanks guys .... what I have tried is take a portion of an ADDDELETEWAYPOINT section macro and a portion of a get aircraft position macro and
tried to fit them in at the top of the ACTDIRECTTOWAYPOINT section macro to try and do what I mentioned in first post.

However I struggle with understanding the code and am finding it hard to find relevant examples to try and stitch things together.

The aircraft(s) in question are the latest bizjets from a well known dev - ? not a Carxxxxx ? The gauge is the 600X? see jay too? and line no. 1395.

They have improved a bit and if I can get this working, even in a rough way, I could use it in Vatsim etc... I've spent days fiddling with it
and I don't seem to have as much hair left as I had...

Karol , thanks for your input but its above my head how that fits in with existing code...

would also be great to be able to save/load flightplans.
