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.
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.
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.
If you're in the air, the rule of thumb for light aircraft (with a typical glide ratio of 8:1) is 1.5nm per 1,000ft AGL, after subtracting 1,000ft or so for flying a pattern around your landing site. Rounding 9,842ft to 10,000ft, that gives a gliding range of 9×1.5=13.5nm, which is close enough in an emergency.
So, what is Normalisation of Deviance? The process of normalisation of deviance can be seen in the “Deviation Spiral” where you can see a deviation from the original normal causes a new normal which, again, can be deviated from, causing another normal.
§ 23.1327 Magnetic direction indicator.
(2) The compensated installation may not have a deviation in level flight, greater than ten degrees on any head- ing.
Pilot deviations are divided into two categories: airborne deviations and ground deviations.
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.
One per cent rule:
point of landing must be less than one per cent of the total distance flown.
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.
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.
Remember the three rules of the air and repeat them after me. Always look before you slip, always slip in the opposite direction to avoid collision, and the lower Jumper always has the right of way.
The rule of three can refer to a collection of three words, phrases, sentences, lines, paragraphs/stanzas, chapters/sections of writing and even whole books. The three elements together are known as a triad. The technique is used not just in prose, but also in poetry, oral storytelling, films, and advertising.

The largest open-class glider, the eta, has a span of 30.9 meters and has a glide ratio over 70:1.
While many can and do become flight instructors to build that flight time, it's not the only way to reach the goal. Glider flight time does count toward an ATP. This is good news for a couple of reasons, not the least of which is the potential for glider time to be cheaper than other forms of flying.
Gliders are efficiency champions. They achieve a glide ratio of 1:70, meaning that for each meter of descent, they can glide for up to 70 meters. Modern commercial aircraft don't even come close. The best they can manage is a ratio of 1:20—and even that requires a huge amount of fuel.
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 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 your employer schedules you for an eight hour rest period, your next rest period must be at least 10 consecutive hours and must begin no later than 24 hours after the beginning of the eight hour rest period. You can find additional guidance on our Cabin Safety Legal Interpretations website.
Senior First Officer
Anyone other than the rank of Captain or Training Captain is sometimes referred to as the 'Co-Pilot'. A Senior First Officer has 3 stripes on their uniform.
In aviation, the first officer (FO), also called co-pilot, is a pilot in addition to the captain, who is the legal commander. In the event of incapacitation of the captain, the first officer will assume command of the aircraft.
This is called a "Brasher Warning," named after an NTSB case from 1987 that established the requirement for ATC to formally acknowledge the possibility that a pilot made a mistake so that they can review the Pilot's Bill of Rights and collect their thoughts. This is equivalent to one's Miranda Rights in the US.
