Question

What is the angle between the normal to the reference ellipsoid and the equatorial plane at a point called?

(a) Geodetic angle

(b) Correction factor

(c) Geodetic latitude

(d) Earth angle

I have been asked this question by my school teacher while I was bunking the class.

The doubt is from Navigation Equations topic in section Introduction & Navigation Equations of Avionics

Answer 1

The correct choice is (c) Geodetic latitude

For explanation I would say: Geodetic latitude of a point is the angle between the normal to the reference ellipsoid and the equatorial plane. Geodetic latitude is our usual understanding of map latitude.
