Astronomic precession
Hello,
I found a question on the JAA ATPL(A) Operation Procedure about Astronomic precession. I suppose they are talking about Earth axis precession (with a period of about 26000 years).
The question is :
Astronomic precession:
Answer: causes an apparent spin of heading gyro to the right in the southern hemisphere.
Well I've tried to think it and to see it many different ways and I just don't get it.
Does someone has a schema or an explanation for that ?
Thank you very much,
Emmanul Cordier.
