Olympic triangle be perfectly sharp, either, since it is a course. Traditionally the configuration of the triangle is an equilateral triangle (3 equal sides and 3 equal angles of 60 degrees) with a ratio of the windward leg to a reaching leg being 1:1. In that case the course length for the 9 legs described above is 9 times the length of the windward leg. The angle at each point of the triangle is 60 degrees. The windward leg is generally aligned with the average wind direction. Another configuration is a triangle with a right angle at the wing mark and 45
1 in 60 rule is required, the numbers work out with the same rule: 1% over 1 NM ≈ 60' It is also useful to find out the lateral deviation from a given VOR course or radial: Each dot on a VOR indicator represents 2° of deviation, or 200' per dot per DME. There are other applications to this rule. One such application is time drift. An hour is equal to 60 minutes, and a minute is equal to 60 seconds, so some other relationships between angle and time can be observed. If a pilot is flying a leg of 120 miles and finds
