1 An aircraft departs from position A (04°10' S 178°22'W) and flies northward following the meridian for 2950 https://youtu.be/i2f-h0Dkh64
NM. It then flies westward along the parallel of latitude for 382 NM to position B. The coordinates of position
B are?
2 The angle between the true great-circle track and the true rhumb-line track joining the following points: A https://youtu.be/Fk3f0g-lXm8

3 Given: Waypoint 1. 60°S 030°W Waypoint 2. 60°S 020°W What will be the approximate latitude shown on the https://youtu.be/BcNEYDr45YM
display unit of an inertial navigation system at longitude 025°W?
4 What is the time required to travel along the parallel of latitude 60° N between meridians 010° E and 030° W https://youtu.be/vejFsDn_TmQ
at a groundspeed of 480 kt?
5 Given: value for the flattening of the Earth is 1/298. Earth's semi-major axis, as measured at the equator, https://youtu.be/Z-gOj6s-gF4
equals 6378.4 km. What is the semi-minor axis (km) of the earth at the axis of the poles?
6 Position A is located on the equator at longitude 130°00E. Position B is located 100 NM from A on a bearing https://youtu.be/sssMAVAoCdU
of 225°(T). The coordinates of position B are:
7 The rhumb line track between position A (45°00'N, 010°00'W) and position B (48°30'N, 015°00'W) is https://youtu.be/2Ws7KIbrb4o
approximately:
8 A Mercator chart has a scale at the equator = 1: 3 704 000. What is the scale at latitude 60° S? https://youtu.be/UiS8iB1qZN8
9 The distance measured between two points on a navigation map is 42 mm (millimetres). The scale of the https://youtu.be/t3rUqMjl_2w
chart is 1:1 600 000. The actual distance between these two point is approximately:
