A straight line from A (75°S, 120°E) to B (75°S, 160°E) is drawn on a Polar Stereographic chart. When passing the meridian 155°E, the True Track is:

On a Polar Stereographic chart, the initial great circle course from 70°N, 060°W to 70°N, 060°E is approximately...

An aeronautical chart has a published scale of 1 inch = 15 NM. An aircraft is flying on a true heading of 089°  with a groundspeed of 150 kt. Calculate the chart distance covered by the aircraft in 25 minutes.

The constant of the cone in a Lambert chart is 0.8666500. The angle between the north directions of the meridian in position A 65°00'N, 018°00'W and the meridian of position B 75°00'N, 023°00'W on the chart is:

An aircraft is flying from A (24°32'N, 166°36'W) to B (34°46'N, 173°20'E). The rhumb line track is 295°(T). Determine the initial great circle track (°T):

An aircraft is flying from waypoint A (32°35'S, 168°12'E) to waypoint B (32°35'S, 165°48'W). Determine the great circle track (°T) on arrival at waypoint B:

What is the Earth convergency for a straight line between position A (37°45'S, 170°25'W) and position B (37°45'S 168°35'E)?

Which of the factors named hereafter should be considered by the pilot when selecting landmarks as visual reference points?

 1. Possibility of identification

 2. Transmitted frequency

 3. Visibility

 4. Closeness to the track

The pilot is in radio contact with an Air Traffic Control unit but has become unsure of the aircraft's position. The pilot's initial action(s) if fuel is NOT critical is:
