MBot Posted March 5, 2017 Share Posted March 5, 2017 In anything else but a cold start, the magnetic declination is wrong. Notice the true heading of 219° in the info bar. Magnetic declination in Las Vegas is 14° E, so magnetic heading will be 205. Aircraft after cold spawn and external power applied. CI and backup compass show magnetic heading of 205°. Correct (even though the CI is flagged). Aircraft after hot spawn. CI shows 219°, which is wrong. Backup compass is still correct with 205°. Also applies to air start.

Dahlbeck Posted March 7, 2017 Share Posted March 7, 2017 Isn't the whole point of setting the declination (variation) on the dial (which I've never been able to rotate btw) that the nav system is supposed to know true heading and the CI thus display the same?

MBot Posted March 7, 2017 Author Share Posted March 7, 2017 The nav system might use true heading for its internal computations, but it would be very strange if this was displayed to the pilot. Every navigation chart and every runway marking uses magnetic heading. Link to comment Share on other sites More sharing options...
Riverseeker Posted July 17, 2017 Share Posted July 17, 2017 (edited) Is magnetic declination dial working? becouse atm i cant rotate that one. Ops, already reported. nevermind :D Edited July 17, 2017 by Riverseeker 200m butterflier inside :harhar: MERLO forever Link to comment Share on other sites More sharing options...
funkyfranky Posted January 16, 2018 Share Posted January 16, 2018 I have never really bothered to use the KURSKORR knob to correctly set the magnetic declination. Now I am starting to wonder how the aircraft actually "knows" the correct local declination? Is this knob "automatically" adjusted to the correct value depending on which map I am even for a cold start?

Yes, it is, and it was sort of a "design by necessity" sort of thing IIRC (it's been a while). The other issues need to be looked at and also whether this feature needs improvement.

Leviathan667 Posted July 31, 2018 Share Posted July 31, 2018 Same thing here. I could not adjust the kurskorr knob but since it is done automatically, then it's all for the best (I still did spend 10 minutes looking for a fix since in the first training lesson, they ask you to adjust that knob).

sc_neo Posted August 1, 2018 Share Posted August 1, 2018 Do i get this right? Do we never have to touch that untouchable declination knob because it is adjusted automatically (design choice) independet of doing a cold start, hot start or spawning in the air? So we don't need to bother with magnetic declination at all atm? Link to comment Share on other sites More sharing options...

The other issues need to be looked at and also whether this feature needs improvement. Thank's Cobra for that clarification. I haven't bother to use KURSKORR-knob, as i doesn't move in cockpit. But began to think of it when the issue was brought up here. Good to know it's automatic. Would be nice if it in the future will be an real funktion in it as it is a part of setting up the plane. :) Edited August 1, 2018 by FanOfALF Regards FanOfALF Link to comment Share on other sites More sharing options...
sc_neo Posted August 1, 2018 Share Posted August 1, 2018 Especially when more and more maps are going to be released. The headache would by with us then if this knob was fully functional! Link to comment Share on other sites More sharing options...
MBot Posted August 2, 2018 Author Share Posted August 2, 2018 Can someone confirm whether the aircraft should really displaying true heading to the pilot? Because I think it is very weird considering navigation charts and runway headings in aviation are using magnetic headings. Link to comment Share on other sites More sharing options...

Skyracer Posted August 5, 2018 Share Posted August 5, 2018 Uhmm ok that seems to be the case. I just find it very old school way instead of using true course. Runways are named by a number between 01 and 36, which is generally the magnetic azimuth of the runway's heading in decadegrees. This heading differs from true north by the local magnetic declination.

bbrz Posted August 5, 2018 Share Posted August 5, 2018 I just find it very old school way instead of using true course. What's 'very old school'? Navigation is always based on magnetic north. The problem is the DCS flat world model which results is a mix of grid north, true north and magnetic north in the sim and in the mission planner. i7-7700K 4.2GHz, 16GB, GTX 1070 Link to comment Share on other sites More sharing options...

Because i doubt that a airliner, cruise ship or a fighter jet are you using the magnetic compass as thier primary navigation tool.

Holton181 Posted August 5, 2018 Share Posted August 5, 2018 (edited) Whats your source? Because i doubt that a airliner, cruise ship or a fighter jet are you using the magnetic compass as thier primary navigation tool.In reality the numbers on the runways are always in magnetic. As surprising it can be, even the most modern aircrafts of today has to have, by regulation, a magnetic compass and other kind of instruments not in need of external systems like electrical power etc. You should always have a backup system avaliable in case of power outage in the cockpit and other similar emergencies. And all aerodromes need to be able to support older/simpler aircrafts without fancy stuff in their cockpit. And to give one example regarding your question in my quote. If the GNSS fail on the aircraft there is only by the earth magnetic field your heading can be determined, even internally by the other positioning systems. INS systems and the like are based on dead reckoning and do accumulate errors over time.
