This is probably a dumb question but I have always used the true heading of a runway on the VOR1 rotating course card. Is that correct or should I be using a runways magnetic heading? Please advise and thanks!Mark

The runways are marked by magnetic headings, that's why they change numbers every so often.

It should be the magnetic course.

Course values mapped on charts including terminal procedures for/or derived from navaids are all declared as magnetic. This includes VOR compass roses, bearings shown on approaches, SIDs, enroute instrument charts, etc. Route bearings shown on VFR charts are labeled in magnetic terms as well. You can see this on a long straight true leg where the magnetic interecepts of a navaid have different values on each end.Bearings from GPS based instruments can give both magnetic and true bearings on demand.

Magnetic, always magnetic my friend. The only situation I know when flying true headings is the normal procedure is when flying above 60

Canada has a demarcation line where true is used, and radials/bearings are suffixed with "T" to ensure no confusion.scott s..

Thanks guys...Hey Scruffy...you might want to rethink whats exported for runways in the ADE list...Mark

The runway Mag heading is not a value that does anything. FS may have at one time thought about using the Mag value but all runways fallback onto the MagDec.bgl.The only way to tweak the Mag heading of a runway is to change the True heading which we do not recommend at ADE. Changing any True Heading distorts all the approach code and both published and non published missed approaches. At this point there is nothing to rethinkjim

All VOR and ILS is based on magnetic headings. So you must ensure you are using that and not true bearings. From the ILS pint of view it is quite easy to change the MAG. bearing in the afcad file of the airport.vololiberista

Interesting...then should we be using True or Magnetic when setting the course card on VOR1? By the way, a suggestion would be to include both magnetic and true headings in ADE...would that be easy to do?Mark

We've already said... magnetic. The entire world uses magnetic for courses and headings... unless otherwise clearly stated on a chart.ADE is a design tool and it's providing the correct values for designing an airport's ILS. It has nothing to do with flying and you probably shouldn't be mixing and matching the two concepts together. :(

OK...I just wanted to make sure...thanks dude!Mark

You know, I've been thinking about this a bit and would still like to see ADE produce both the magnetic and true headings. I'm being a bit selfish but I've written a utility that outputs airport information into HTML and then displays it in the knee board. Its alphabetized and really easy to use. That way, no matter where I fly I always can find which VOR I'm after and what to set the VOR1 course card to. It's simply a matter of convenience and that way I don't have to have or create a specific flight plan. I can just wing it. So the thing of it is I still would like to get that info and don't want to hunt around to find it, and, it was in Afcad2. If Jim or Scruffy decides to do it then it would be great for me...and I hope for others too. But its their app and they were kind enough to make it for the FS community so I wouldn't want to look a gift horse in the mouth :)Mark

The user created guideline in ADE does provide a true/magnetic bearing info so that's available. Magvar is in the airport and VOR properties, so magnetic can be computed in your utility. Keep in mind though that there have been replacement magdec.bgl files for FS9 and no doubt newer ones will be done eventually, so what you see in FS or on a chart may not match what is in the data files.scott s..
