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?

It's called the 3-2-1 rule, and it's the easiest way to remember the regulation. To recap, if the weather at your destination isn't at least 3 SM of visibility and 2000' AGL ceilings from 1 hour before to 1 hour after your ETA, you need to file an alternate.


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?

(1) A rest required under paragraph (b)(1) of this section may be scheduled for or reduced to a minimum of 8 hours if the flight crewmember is given a rest period of at least 10 hours that must begin no later than 24 hours after the commencement of the reduced rest period.


What is the 12 5 rule in aviation?

The Twelve-Five Standard Security Program (TFSSP) outlines requirements for FAA Part 135 certificated carriers offering commercial air transport using aircraft with a maximum certificated takeoff weight between 12,500 pounds (5,670 kg) and 100,309.3 pounds (45,500 kg).


What is the 1000ft rule in aviation?

1000 ft rule. An aircraft must maintain an altitude of 1,000 feet above the highest obstacle within a horizontal radius of 2,000 feet of the aircraft over any congested area of a city, town, or settlement, or over any open air assembly of persons.
