AVIATION & AERONAUTIC CALCULATOR
1 In 60 Rule
A precise tool.
What is the 1 In 60 Rule & How does it work?
The 1-in-60 rule is a simplified method used in aviation to estimate the track error and closing angle between two aircraft. This rule assumes that for every 60 nautical miles (nm) of separation, there is approximately 1 degree of difference in their tracks.
text{Track Error} = frac{text{Separation Distance}}{60}
Track Error = Track error in degrees
Separation Distance = Distance between aircraft in nautical miles
Separation Distance = Distance between aircraft in nautical miles
This rule is particularly useful for quick mental calculations and provides a rough estimate of the potential collision risk based on track separation.

Frequently Asked Questions
What is the 1-in-60 rule in aviation?
The 1-in-60 rule is a simplified method for estimating the track error and closing angle between two aircraft. It assumes that for every 60 nautical miles of separation, there is approximately 1 degree of difference in their tracks.
How do you use the 1-in-60 rule?
To use the 1-in-60 rule, divide the separation distance between aircraft (in nautical miles) by 60 to get the track error in degrees.
What is the purpose of the 1-in-60 rule?
The 1-in-60 rule is used for quick mental calculations to estimate the track error and closing angle between two aircraft, providing a rough approximation for situational awareness in aviation.
Can the 1-in-60 rule be applied to all types of aircraft?
Yes, the 1-in-60 rule can be applied to various types of aircraft as it is a general guideline based on separation distances and track differences.
What are the limitations of the 1-in-60 rule?
The 1-in-60 rule provides a rough estimate and does not account for factors such as wind, aircraft performance, or specific flight conditions. It is best used for quick mental calculations.
How accurate is the 1-in-60 rule?
The 1-in-60 rule offers a simplified approximation and may not be highly precise. It is most useful for rough estimates and situational awareness in aviation.
Is there a similar rule for other units of measurement?
Yes, while the 1-in-60 rule uses nautical miles, similar rules can be adapted for other units based on specific operational needs or regional standards in aviation.
