Equidistant from the poles is an imaginary circle called...
Equator
Drawn from pole to pole at right angles to the equator
Meridians of longitude
Used as the zero degree line
Prime meridian
Lat and Long: which is stated first?
Latitude
Where longitudinal meridians converge
True North
Attracts the needle of a compass
Magnetic North
Angular difference b/t true north and magnetic north
Magnetic variation
Depicted on sectional charts using dashed magenta colored lines
Isogonic lines (equal variation)
Points where magnetic north and true north are the same
Agonic line
Course measured with respect to true north (using lat and long
True Course (TC)
Course with respect to magnetic north
Magnetic course (MC)
Time at the prime meridian and is represented in aviation operations by the letter Z
Coordinated Universal Time (UTC)
