Flight Rules
Flight rules are regulations and procedures adopted for flying aircraft in various conditions. Flight rule regimes include: * Instrument flight rules, regulations and procedures for flying aircraft by referring only to the aircraft instrument panel for navigation * Night visual flight rules, the rules under which flight primarily by visual reference is done at night * Special visual flight rules, a set of aviation regulations under which a pilot may operate an aircraft * Visual flight rules, a set of regulations which allow a pilot to operate an aircraft in weather conditions generally clear enough to allow the pilot to see where the aircraft is going See also * Instrument meteorological conditions, weather conditions that normally require pilots to fly under instrument flight rules * Visual meteorological conditions In aviation, visual meteorological conditions (VMC) is an aviation flight category in which visual flight rules (VFR) flight is permitted—that is, conditions in w ...

Instrument Flight Rules
In aviation, instrument flight rules (IFR) is one of two sets of regulations governing all aspects of civil aviation aircraft operations; the other is visual flight rules (VFR). The U.S. Federal Aviation Administration's (FAA) ''Instrument Flying Handbook'' defines IFR as: "Rules and regulations established by the FAA to govern flight under conditions in which flight by outside visual reference is not safe. IFR flight depends upon flying by reference to instruments in the flight deck, and navigation is accomplished by reference to electronic signals." It is also a term used by pilots and controllers to indicate the type of flight plan an aircraft is flying, such as an IFR or VFR flight plan. Basic information Comparison to visual flight rules It is possible and fairly straightforward, in relatively clear weather conditions, to fly an aircraft solely by reference to outside visual cues, such as the horizon to maintain orientation, nearby buildings and terrain features for n ...

Night Visual Flight Rules
Night visual flight rules (NVFR) are the visual flight rules under which a flight may be performed at night primarily by visual reference. The alternative is flight by instrument flight rules (IFR), under which visual reference to terrain and traffic is not required. In EASA countries the requirements for a NVFR rating (at an approved training organisation) are: * total of 5 hours of VFR flying at night (NVFR), * including 3 hours ''dual'' flying (with an instructor), * including 5 take-offs and landings at night, * including 1 dual navigational flight by visual flight rules at night, at least 50 km and 1 hour. In many countries, NVFR is not permitted, in which case night flying is by IFR which requires an instrument rating Instrument rating refers to the qualifications that a pilot must have in order to fly under instrument flight rules (IFR). It requires specific training and instruction beyond what is required for a private pilot certificate or commercial pilot .... Coun ...

Special Visual Flight Rules
Special visual flight rules (also special VFR or SVFR) are a set of aviation regulations under which a pilot may operate an aircraft. It is a special case of operating under visual flight rules (VFR). Use in different regions The definition for SVFR may be different in different countries, depending on the local aviation regulations. ICAO definition The ICAO definition of Special VFR flight is a VFR flight cleared by air traffic control to operate within a control zone in meteorological conditions below visual meteorological conditions. United States According to Federal Aviation Regulations, SVFR operations can only be conducted in the controlled airspace around an airport where that controlled airspace extends down to the surface (so-called ''surface area''). SVFR can only be conducted below 10,000 feet MSL in such areas. SVFR at night requires an IFR-equipped aircraft and an IFR-rated pilot in command ("IFR" means Instrument flight rules). In helicopters, there is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Visual Flight Rules
In aviation, visual flight rules (VFR) are a set of regulations under which a pilot operates an aircraft in weather conditions generally clear enough to allow the pilot to see where the aircraft is going. Specifically, the weather must be better than basic VFR weather minima, i.e. in visual meteorological conditions (VMC), as specified in the rules of the relevant aviation authority. The pilot must be able to operate the aircraft with visual reference to the ground, and by visually avoiding obstructions and other aircraft. If the weather is less than VMC, pilots are required to use instrument flight rules, and operation of the aircraft will be primarily through referencing the instruments rather than visual reference. In a control zone, a VFR flight may obtain a clearance from air traffic control to operate as Special VFR. Requirements VFR require a pilot to be able to see outside the cockpit, to control the aircraft's altitude, navigate, and avoid obstacles and other aircraft ...

Instrument Meteorological Conditions
In aviation, instrument meteorological conditions (IMC) is a METAR, flight category that describes weather conditions that require pilots to fly primarily by reference to Flight instruments, instruments, and therefore under instrument flight rules (IFR), rather than by outside visual references under visual flight rules (VFR). Typically, this means flying in cloudy or bad weather. Pilots sometimes train to fly in these conditions with the aid of products like Foggles, which are specialized glasses that restrict outside vision, forcing the student to rely on instrument indications only. Distinction from Visual Meteorological Conditions The weather conditions required for flight under VFR are known as visual meteorological conditions (VMC). IMC and VMC are mutually exclusive. In fact, instrument meteorological conditions are defined as less than the minima specified for visual meteorological conditions. The boundary criteria between VMC and IMC are known as the VMC minima. There is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Visual Meteorological Conditions
In aviation, visual meteorological conditions (VMC) is an aviation flight category in which visual flight rules (VFR) flight is permitted—that is, conditions in which pilots have sufficient visibility to fly the aircraft maintaining visual separation from terrain and other aircraft. They are the opposite of instrument meteorological conditions (IMC). The boundary criteria between IMC and VMC are known as the VMC minima and are defined by: visibility, cloud ceilings (for takeoffs and landings), and cloud clearances. The exact requirements vary by type of airspace, whether it is day or night (for countries that permit night VFR), and from country to country. Typical visibility requirements vary from one statute mile to five statute miles (many countries define these in metric units as 1,500 m to 8 km). Typical cloud clearance requirements vary from merely remaining clear of clouds to remaining at least one mile away (1,500 m in some countries) from clouds horizontally and 1 ...

Aviation Safety
Aviation safety is the study and practice of managing risks in aviation. This includes preventing aviation accidents and incidents through research, educating air travel personnel, passengers and the general public, as well as the design of aircraft and aviation infrastructure. The aviation industry is subject to significant regulation and oversight. Aviation security is focused on protecting air travelers, aircraft and infrastructure from intentional harm or disruption, rather than unintentional mishaps. Statistics Evolution In 1926 and 1927, there were a total of 24 fatal commercial airline crashes, a further 16 in 1928, and 51 in 1929 (killing 61 people), which remains the worst year on record at an accident rate of about 1 for every flown. Based on the current numbers flying, this would equate to 7,000 fatal incidents per year. For the ten-year period 2002 to 2011, 0.6 fatal accidents happened per one million flights globally, 0.4 per million hours flown, 22.0 fatal ...
