For larger aircraft, typically people use some form of the 3/6 Rule: 3 times the altitude (in thousands of feet) you have to lose is the distance back to start the descent; 6 times your groundspeed is your descent rate.
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. For example, a descent from flight level 350 would require approximately 35x3=105 nautical miles.
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.
Assess what is required to fly the missions you execute most often, and these are your must-haves regardless of the purchase. By nature these needs should influence roughly 90 percent of your decision. The other 10 percent is generally based on emotion.
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.
Rule 58 of Aircraft Rules, 1937 requires that every aircraft shall be weighed and its centre of gravity determined.
The 80:20 rule means airlines need to use their take-off slots at least 80% of the time in order to retain them. A "justified non-use provision" will be retained to prevent airlines flying ghost flights.
(a) in any part of an aircraft or in its vicinity, in which a notice is displayed indicating that smoking is prohibited.
—No person shall take, or cause or permit to be taken, at a Government aerodrome or from an aircraft in flight, any photograph except in accordance with and subject to the terms and conditions of a permission in writing granted by the Director-General, a Deputy Director-General, the Director of Regulations and ...
When you are 20, you care about what everybody thinks of you. When you are 40, you don't care about what people think of you, and when you are 60, you actually understand that people were too busy thinking about themselves. In essence, don't agonize about what other people are thinking about you.
This rule of thumb is incredibly powerful in the aviation environment. It states that for each degree off (or displacement) over a distance of 60 nautical miles (NM), it will result in 1 NM off course. It can be applied in various areas of interest when flying, and is easily remembered.
One degree of latitude equals approximately 364,000 feet (69 miles), one minute equals 6,068 feet (1.15 miles), and one-second equals 101 feet.
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).
Instruments and Equipment: Rule 57 of Aircraft Rules, 1937 and Civil Aviation Requirements Section 2 - Airworthiness Series 'I' Part II and Series 'R' Part I- Provides for minimum instruments and equipment including Communication and Navigation equipment which are to be installed on aircraft depending on their ...
1 hour before to 1 hour after your ETA (at the listed destination), the ceiling will be at least 2,000′ AGL, and the visibility will be at least 3 SM. It's called the 1-2-3 rule; this is the easiest way to remember this section.
In aviation medicine, the 1% rule is a risk threshold that is applied to the medical fitness of pilots. The 1% rule states that a 1% per annum risk (See also risk management) of medical incapacitation is the threshold between acceptable and unacceptable.
What is the 50/70 rule? It's a general rule for GA aircraft that states if you haven't reached 70% of your takeoff speed by the time you've reached 50% of the length of the runway, you should abort your takeoff. Why do you need 70% of your takeoff speed by 50% of the runway?
If no obstacle or terrain penetrates a 40:1 slope (termed the obstacle clearance surface (OCS) or obstacle identification surface (OIS)) from the departure end of the runway (DER), an aircraft may turn in any direction and remain clear of obstacles while climbing at 200‗/NM.
While flights have a scheduled departure time, there is an unwritten final-boarding rule. The gate agent will often close the door to the plane 10 minutes before departure, which, depending on what side of the door you're on, can either mean a huge sigh of relief or a delayed or even ruined trip.
In general, except when necessary for take-off or landing, an aircraft should be 1,000 ft over a built-up area or otherwise 500ft from people, vehicles, vessels and structures.
(b) an authorisation, approval or certificate of competency shall remain valid for a period specified therein, subject to a maximum period of one year in each case, and may be renewed for another one year at a time on receipt of application for renewal, provided the applicant has engaged himself in the performance of ...
It is simply math: if you multiply the distance to go (in feet) by the tangent of 3 degrees you get the height at that point (in feet). For a 3 degree glide path that comes to 318 feet every nautical mile. Or you can round that to 320 feet per nautical mile, or even 300 feet per nautical mile.
For example, a certain flight may have a calculated ETA based on the speed by which it has covered the distance traveled so far. The remaining distance is divided by the speed previously measured to roughly estimate the arrival time.
Option 1: Multiply Your Groundspeed By 5
If you're flying your aircraft on a roughly 3-degree glideslope, try multiplying your groundspeed by 5 to estimate your descent rate. The result will be a FPM value for descent that you should target.
