Primarily, the “ILS,” as it is commonly known, consists of two radio beams emitted from transmitters right next to the runway. All pilots have to do is follow the beams down to 200 feet above the ground, at which point they must be able to see the runway and its approach lights.

Primarily, the “ILS,” as it is commonly known, consists of two radio beams emitted from transmitters right next to the runway. All pilots have to do is follow the beams down to 200 feet above the ground, at which point they must be able to see the runway and its approach lights.
Weather, in particular wind speed and direction, is usually the main reason for selecting which runways are used at an airport, the direction aircraft take-off and land, and the flight paths that are used.
A runway labeled 36 will be aligned for both takeoffs and landings on headings between 355 and 005 Magnetic North. The numbers on the runway are large enough to be clearly seen from a mile away. Even if you can not see the numbers, the runway can be identified using a standard magnetic compass or heading indicator.
Pilots do NOT land their airplane when they cannot see the runway! However, Instrument Landing System (ILS) is a set of radio signals that will allow a pilot to line up on a runway that he cannot see. It will direct the aircraft to the end of the runway.
All takeoffs and most landing are done manually. In reduced visibility conditions, many airliners utilize auto land where the autopilot(s) perform the landing under the close monitoring of the pilots.
In some situations, such as during a landing on a contaminated runway, the firm touchdown may have been intentional. As stated in the definition above, a hard landing is classified as the exceedance of a manufacturer limitation, which will vary by the category and purpose of the aircraft.
The Boeing 747 is considered to have the longest takeoff distance of the more common aircraft types and has set the standard for runway lengths of larger international airports. At sea level, 3,200 m (10,500 ft) can be considered an adequate length to land virtually any aircraft.
Since most runways are oriented to take advantage of prevailing winds to assist in takeoffs and landings, they can be used either direction. This is why most runways have two numbers. The second number differs by 18 or 180 degrees.
Planes must take off and land into the wind, so the direction of arrivals and departures is determined almost exclusively by wind direction. Approximately 70 percent of take offs annually are to the east with landings from the west. About 30 percent of take offs annually are to the west with landings from the east.
At night pilots will turn their gaze from outside to inside and use the artificial horizon. The artificial horizon is normally a simply globe split into two hemispheres. Using this instrument, the pilot can determine whether the aircraft is in a climb, a dive, or rolling.
The airlines use the last hours of the day and the first hours of the night to catch up on delays and ensure their aircraft are in the right place for the next day. Night Flights allow the budget airlines and the non-scheduled airlines (usually operating holiday charter flights) to make full use of their aircraft.
Whether flying at night or during the day, pilots need to see some kind of horizon. They use this to determine the airplane's attitude. At night pilots will turn their gaze from outside to inside and use the artificial horizon. The artificial horizon is normally a simply globe split into two hemispheres.
Runway numbers are determined by rounding the compass bearing of one runway end to the nearest 10 degrees and truncating the last digit, meaning runways are numbered from 1 to 36—as per the diagram below. The opposite end of the runway always differs by 180 degrees, so it's numbered 18 higher or lower.
The airfield is managed by three FAA air traffic control towers. O'Hare has a voluntary nighttime (22:00–07:00) noise abatement program. Currently, O'Hare has the most runways of any civilian airport in the world, totaling eight.
In 1958, that Cessna 172 flew nonstop for 64 days, 22 hours and 19 minutes and covered 150,000 miles (240,000 kilometers). That's about six times around the Earth or 15 Sydney-New York flights without touching the ground, and still stands as a world record, according to the Guinness World Records.
Shigatse Peace Airport, China (runway length: 5,000m)Shigatse Peace Airport (RKZ), a dual-use military and civilian airport in Shigatse, Tibet hosts the longest runway in the world. The new runway (09/27) stretches 5,000m (16,404 ft) long with a 60-meter asphalt overrun at each end.
As Atlas Obscura explains, the numbers that runways have aren't arbitrary. A runway always has a number between 1 and 36, and that number isn't just the runway's nickname, but also indicates how many degrees away that runway is from magnetic north, rounded to the tens.
