The ATCT supervisor/controller-in-charge (CIC) determines which runway/s are designated RUNWAY IN USE/ACTIVE RUNWAY/DUTY RUNWAY.

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.
How does a pilot know which runway to use at an uncontrolled airport? The pilot determines which direction the wind is blowing and the velocity and then uses that information to choose the appropriate runway. The intent, of course is to land with as much headwind component and on the longest runway if possible.
Runways are built to align with historical wind patterns specific to each airport because aircraft land and take off into the wind. At the Minneapolis-St. Paul International Airport (MSP), two parallel runways are oriented northwest to southeast to align with prevailing winds experienced in the Upper Midwest.
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.
Air traffic controllers monitor wind and runway selection at all times, as weather conditions can quickly change. Pilots also monitor and report wind changes and can request a runway that is best suited to the capability of their aircraft.
The letters, differentiate between left (L), right (R), or center (C) parallel runways, as applicable: For two parallel runways “L” “R.”For three parallel runways “L” “C” “R.”
Advertisement. The first digit in the number uses the actual bearing and the second digit is rounded off to the nearest degrees. The last number in the degree is always dropped. Advertisement. So if a runway number is 27, it means that the direction of the runway is 270-degrees from North.
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.
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.
It is a fact that both the takeoff and landing phases have their own set of challenges. Some may argue that the landing phase of a flight requires more pilot skills; but based on experience, it is just the same for takeoff. The difficulties experienced by pilots during takeoff are technically the same during landing.
Airlines pay a fee to land at any airport and use the required facilities there. Fees vary significantly between airports and consider different factors, including aircraft type and weight, landing time, and sometimes emissions and noise.
The fact that the left-hand seat of a two-person cockpit is reserved for the aircraft's captain dates back to the decades before the advent of jet-powered engines. According to Ask Captain Lim, this tendency came about due to the nature of early rotary-driven aircraft, such as fighter aircraft from the First World War.
Ensures Overall Aviation SafetySafety risk is significantly higher when a single pilot flies an aircraft, so dual pilot operations are almost always mandatory. With two pilots, the workload is split thereby decreasing stress significantly.
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.
Runways will be numbered based on their position so 06/24 means one end of our runway is 60 degrees, the opposite end is 240 degrees – so 180 degrees, also known as a straight line!
ICAO SARPs relating to runways are determined according to runway length using the standard Runway Code categories. Code 1 runways are less than 800 metres long, Code 2 runways are 800-1199 metres long, Code 3 runways are 1200-1799 metres long and Code 4 runways are 1800 metres or more in length.
