Compass Questions ?
Hi,
Thanks for replies and help.
What I was referring to are the new, modern, "glass" displays where most
everything shown is derived
from transducers located elsewhere.
e.g. when a display shows a Heading of, e.g., 075, it is of course
getting this info. from some kind of transducer, located elsewhere.
Is it derived directly from GPS ?
A Hall effect compass ?
or,... ?
Thanks again; interesting subject.
Bob

Hello,
Not a Pilot, but always interested in the engineering aspects.
This question came up, and I realize that I am not sure of a correct
answer.
Regarding the compass heading that shows in the glass displays:
How is it derived ?
GPS ?
If not GPS, what ?
Is it then Magnetic or True ?
Does the Pilot have to correct for variation/declination changes during
a flight ?
Does aviation use True or Magnetic when discussing or flying ?
etc. ?
Thanks,
Bob
