1 in 60 Rule Calculator

Calculate Track Error (E)



Formula

The formula to calculate the Track Error (E) using the 1 in 60 rule is:

\[ E = \frac{D \times \theta}{60} \]

Where:

Example

Let's say the distance flown (\( D \)) is 120 nautical miles and the angle of deviation (\( \theta \)) is 2 degrees. Using the formula:

\[ E = \frac{120 \times 2}{60} \]

We get:

\[ E = 4 \text{ nautical miles} \]

So, the Track Error (\( E \)) is 4 nautical miles.

What is the 1 In 60 Rule?

The 1 in 60 rule is a rule of thumb in aviation where a one-degree error in the flight path will produce a track error of approximately 1 nautical mile after 60 nautical miles of flight. It is used for quick mental calculations for navigation and error correction, particularly in visual flight conditions. The rule is based on the small-angle approximation of trigonometry.

1 in 60 Rule

Definition: The 1 in 60 rule is used in aviation to estimate the amount of drift correction needed. It states that if a pilot is off course by 1 degree, after 60 miles, they will be 1 mile off course.

Formula: \( \text{Drift} = \frac{\text{Distance} \times \text{Degrees Off Course}}{60} \)

Example: \( \text{Drift} = \frac{120 \times 2}{60} \)

How to Calculate 60% of a Number

Definition: Calculating 60% of a number involves finding 60 percent of the given number.

Formula: \( \text{Result} = \text{Number} \times 0.60 \)

Example: \( \text{Result} = 150 \times 0.60 \)

50+1 Rule

Definition: The 50+1 rule is a regulation in German football that ensures clubs are majority-owned by their members.

Formula: \( \text{Ownership} = \frac{\text{Shares Owned by Members}}{\text{Total Shares}} \times 100 \)

Example: \( \text{Ownership} = \frac{51}{100} \times 100 \)
