chart projections, plotting, and global timekeeping (copy)

great circle route

course lines: a great circle is a circle formed by continuing the arc inscribed by connecting the shortest distance between two points on a sphere

lambert conformal charts

conic projection and developed by placing a secant cone over earth, intersecting the earth at two lines of latitude called “standard parallels”

characteristics of a lambert projection chart

parallels

meridians

scale

great circle

four types of lambert conformal charts

sectional aeronautical chart, operation navigation chart (ONC), tactical pilotage chart (TPC), terminal area chart (TAC)

define course, track, heading

course - aircrafts intended flight path

track - aircrafts acutual flight path over the ground

heading - angular distance of the aircrafts longitudinal axis from a reference

magnetic variation

angular difference between true north and magnetic north

global time keeping system

universal coordinated time (UTC) aka Zulu time

how many hours are in 360 and how many degrees make a hour
