What is pilot rule of three?
What is pilot rule of three? In aviation, the rule of three or 3:1 rule of descent is a rule of thumb that 3 nautical miles (5.6 km) of travel should be allowed for every 1,000 feet (300 m) of descent.
What is the rule of thumb for 3 degree descent?
For a 3 degree glideslope, required rate of descent in feet per minute is approximately equal to ground speed in knots multiplied by 5.
What is the rule of 3 in aviation?
A general rule of thumb for initial IFR descent planning in jets is the 3 to 1 formula. This means that it takes 3 NM to descend 1,000 feet. If an airplane is at FL 310 and the approach gate or initial approach fix is at 6,000 feet, the initial descent requirement equals 25,000 feet (31,000–6,000).
What is the 1 60 rule in aviation?
That's why pilots are taught the 1 in 60 rule, which states that after 60 miles, a one-degree error in heading will result in straying off course by one mile. Which means the lake you planned to fly over could turn out to be a mountain.
What is the FAA 3 2 1 rule?

What is the VOR rule of 60?
The 1 in 60 rule states that if you're off course by 1NM after 60 miles flown, you have a 1-degree tracking error. Time to correct that heading! Another tip: If you're 60 miles away from a VOR, and you're off course by one degree, you're off course by one mile.
What is the 2 3 rule in aviation?
Many pilots refer to this as the 1-2-3 rule: Plus or minus 1 hour from arrival, ceilings at least 2,000 feet and visibility at least 3 statute miles.
What is the 10 24 rule in aviation?
