In the field of aviation medicine, the 1 percent rule is a risk threshold that is applied to the medical fitness of pilots. The 1 percent rule states that a 1% per annum risk (See also Risk management) of medical incapacitation is the threshold between acceptable and unacceptable.
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.
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.
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).
Welcome on board (flight reference). This is Captain / Co-pilot (your name) speaking and I have some information about our flight. Our flight time today will be (flight duration) and our estimated time of arrival in (destination) is (ETA)local time.
Pilot – “If the passengers on the right will look to their left, they will have the perfect view of the passengers on the left.”
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.
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.
Definition: The 5/20 rule is a norm of the Indian Aviation Ministry under which national carriers are required to have five years of operational experience and a fleet of minimum 20 aircraft to fly overseas. This is applicable to all commercial aviation organisations flying passengers.
(b) refuse to follow a lawful instruction given by the Pilot-in-Command, or on behalf of the Pilot-in-Command by a crew member, for the purpose of ensuring the safety of the aircraft or of any person or property on board or for the purpose of maintaining good order and discipline on board.]
A very simple rule of thumb is to add 2% to the calibrated airspeed for every 1000 ft of altitude.
Rule 58 of Aircraft Rules, 1937 requires that every aircraft shall be weighed and its centre of gravity determined.
(2) It shall be a defence to any proceedings for contravention of or failure to comply with these rules if the contravention or failure is proved to have been due to accident, stress of weather or other unavoidable cause; and it shall be a defence to any proceedings under these rules against the owner, hirer, operator, ...
When there is more than one pilot in the cockpit, if a situation arises where one pilot becomes startled, the other pilot can regain the pilot in focus's attention and bring their focus back to the situation, regaining all senses.
Currently, while the International Civil Aviation Organization (ICAO) standards allow a person between the age of 60 and 65 to serve as pilot in command (PIC) of an airplane with two or more pilots, in international commercial air transport operations, the PIC must be paired with a pilot younger than 60 years of age.
The 90-day rule applies when carrying passengers. The licence holder must have completed within the previous 90 days, three take-offs and landings as sole manipulator of the controls in the same type or class to be used on the flight.
Rule 57 of the Aircraft Rules, 1937 requires that every aircraft shall be fitted and equipped with instruments and equipment, including radio apparatus and special equipment as may be specified according to the use and circumstances under which the flight is to be conducted.
(a) in any part of an aircraft or in its vicinity, in which a notice is displayed indicating that smoking is prohibited.
90 percent of the time, the pilot's attention should be outside the flight deck. No more than 10 percent of the pilot's attention should be inside the flight deck. smoothly, and accurately applied with reference to the natural horizon.
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.
Most maintenance personnel have heard of the 18-inch rule and know what it means. For those who don't, the 18-inch rule means that whenever you do Use the right fluid, in the right maintenance or inspect an aircraft, you should not focus on just that task or specific area alone.
Under the 28-day rule, helicopter and fixed wing aircraft can be operated from appropriate sites for no more than 28 days in total in any calendar year. An aircraft for personal use can be operated from within a residential curtilage without planning permission, but only if it's considered to be an ancillary use.
To help pilots better apply the principles of ADM, the FAA adopted the 3-P Model (Perceive — Process — Perform). This three-step process offers a simple, systematic approach to accomplishing each ADM task during all phases of flight.
(30/70 Rule) — If you must clear obstructions on takeoff, you'll need to have 70% of your rotation speed by the time you've traveled 30% of your available takeoff distance.
Hickox: The three C's pertain to cockpit, cabin, and crew, aligned with the three main domains on board the aircraft.
