1 in 60 Rule Formula:
From: | To: |
The 1 in 60 rule is a navigational rule of thumb used in aviation. It states that for every 1 degree of angular deviation from course, you will be approximately 1 nautical mile off track after traveling 60 nautical miles.
The calculator uses the 1 in 60 rule formula:
Where:
Explanation: This rule provides a quick mental calculation for pilots to determine the necessary course correction to return to their intended track.
Details: The 1 in 60 rule is essential for dead reckoning navigation, VFR flight planning, and quick course corrections without sophisticated navigation equipment. It helps pilots maintain accurate track and make timely adjustments.
Tips: Enter the distance you are off track in nautical miles and the distance you have flown along your current track. Both values must be positive numbers greater than zero.
Q1: How accurate is the 1 in 60 rule?
A: The rule is approximate but highly practical. For small angles (less than 10 degrees), it's accurate enough for most aviation purposes. The error increases with larger angles.
Q2: Can this rule be used for wind correction?
A: Yes, the 1 in 60 rule is commonly used to calculate wind correction angles and track corrections due to crosswinds.
Q3: What are the limitations of this rule?
A: The rule becomes less accurate for large angles (over 20 degrees) and over very long distances. It assumes a spherical earth and constant conditions.
Q4: Is this rule only used in aviation?
A: While primarily used in aviation, the principle can be applied to any navigation scenario including marine navigation and land navigation.
Q5: How do pilots use this in real-time navigation?
A: Pilots mentally calculate corrections during flight by estimating distances and applying the rule to maintain or regain their intended track.
