The one-in-sixty rule is a very useful and agile approximation to solve practical problems regarding both lateral and vertical air navigation.

The most obvious advantage of this rule is the avoidance of trigonometric functions rendering the calculations a matter of simple arithmetic procedures.

This mobile application allows the user to practice this rule-of-thumb. Also, it allows for the study of its accuracy.
