Request; Runway centerlines........

[Bob Price 1056465]

I'm not sure if anyone has mention this or even whether it's possible.

Being able to designate the runway centerlines at a different heading than the runways.

We have several airports with offset approaches where the approach doesn't line up with the centerline of the runway.

As the center line is been draw from the rwy heading, taken from the .sct file, it is not possible at present. But there is nothing impossible, especially for Gregery. Registered in Mantis => http://euroscope.hu/mantis/view.php?id=418

Bob,

 

Does it mean an offset and requires a parallel line to the RWY or do you need an angle too?

[Michael Pike]

In some cases, the approach localiser beam is not on the same bearing as the runway. The bearing for the line is defined in the .sct file in the [RUNWAY] section. In VRC, this bearing is used to draw the "centre line" from the threshold coordinates. Euroscope doesn't seem to use this angle.

Michael,

 

I added the extra information to the issue, and changed its state to BUG, as if this information is available in the SCT file then we have to use it.

That's why at VACC-SAG we have defined our own runway-centrelines. We simply draw them using the STAR-function. If you wish to see it, go and have a look here: Basle-Mulhouse (LFSB) download the Standard IFR sector file cycle 0809 v1 and centre yourself at LFSB. Now go and activate LFSB VD 34 from the STAR-display. You'll see that the "centreline" is showing now the final approach of the VOR-DME-approach runway 34. If you would like to compare it with the charts, you can find them at the same page linked above.
