Gyros vs Brain
Going through a Bristol Instruments feedback paper & I've had a falling out with the following question.
A horizontal gyro aligned with the local meridian at the equator experiences :
(a) No apparent drift & no apparent topple
(b) No apparent drift & max apparent topple
(c) Max apparent drift & no apparent topple
(d) Max apparent drift & max apparent topple
The answer given in the feedback is A. I would say B is correct as
Apparent Drift = 15 x sin lat deg/hr
Apparent Topple = 15 x cos lat deg/hr
Is there an error in the feedback or am I a muppet. For the sake of my sanity - someone please sort this out...
Thanks in advance
