1. A course of 120° (T) is drawn between X (61° 30N) and Y (58° 30N) on a Lambert Conformal conic chart with a scale of 1: 1 000 000 at 60° N. The chart distance between X and Y is: A) 66.7 cm B) 33.4 cm C) 38.5 cm D) 36.0 cm

2. A polar Stereographic chart is overlaid with a grid aligned with the Greenwich Anti-Meridian. An aircraft sets off from 80° S 020° E on a grid track of 340° (G). Determine the initial great circle track (° T).
A) 160° (T)
B) 140° (T)
C) 320° (T)
D) 180° (T) pls explain this

3. On a Polar Stereographic chart, the initial great circle course from A 70° N 060° W to B 70° N 060° E is approximately: A) 330° (T) B) 210° (T) C) 150° (T) D) 030° (T)

4. Two positions plotted on a polar stereographic chart, A (80° N 000° ) and B (70° N 102° W) are joined by a straight line whose highest latitude is reached at 035° W. At point B, the true course is: A) 023° B) 247° C) 203° D) 305°
