Practise General Navigation
The following waypoints are entered into an inertial navigation system (INS): WPT 1: 60N 30W WPT 2: 60N 20W WPT 3: 60N 10WThe inertial navigation is connected to the automatic pilot on the route WP1 - WP2 - WP3. The track change on passing WPT 2:
Which statement about meridians and their local directions is correct on a spherical Earth?
What is the standard formula for convergency?
In the spherical Earth model, an INS-coupled autopilot follows the shortest great-circle arc from 60 degrees S 30 degrees W to 60 degrees S 20 degrees W. At 25 degrees W, what latitude is shown, rounded to the nearest whole minute?
An aircraft departs from position A (04°10' S 178°22'W) and flies northward following the meridian for 2950 NM. It then flies westward along the parallel of latitude for 382 NM to position B. The coordinates of position B are?
The angle between the true great-circle track and the true rhumb-line track joining the following points: A (60° S 165° W) B (60° S 177° E), at the place of departure A, is:
Position A is located on the equator at longitude 130°00E. Position B is located 100 NM from A on a bearing of 225°(T). The coordinates of position B are:
The maximum difference between geocentric and geodetic latitude occurs at about:
A great circle track joins position A (59°S 141°W) and B (61°S 148°W). What is the difference between the great circle track at A and B?
Given: A is N55° 000° B is N54° E010°The average true course of the great circle is 100°. The true course of the rhumbline at point A is:
