The Aircraft Classification Number (ACN) – Pavement Classification Number (PCN) method is a standardized international airport pavement rating system promulgated by the ICAO in 1981.
Runway Holding Position Markings These show where an aircraft should stop when approaching a runway from a taxiway. They consist of four yellow lines, two solid and two dashed, spaced six or twelve inches (15 or 30 cm) apart, and extending across the width of the taxiway or runway. The solid lines are always on the side where the aircraft is to ...
Runway centerline lighting system (RCLS) – lights embedded into the surface of the runway at 50 ft (15 m) intervals along the runway centerline on some precision instrument runways. White except the last 900 m (3,000 ft): alternate white and red for next 600 m (1,969 ft) and red for last 300 m (984 ft).
[1] [2] [3] Although the use of the apron is covered by regulations, such as lighting on vehicles, it is typically more accessible to users than the runway or taxiway. However, the apron is not usually open to the general public, and a permit may be required to gain access. An apron's designated areas for aircraft parking are called aircraft ...
TALPA assessment generates a Runway Condition Code (RWYCC) ranging from 6 to 0, where 6 indicates a dry runway and 0 signifies nil conditions, meaning braking action is minimal to non-existent. Separate runway condition codes are published for each third of a runway, and pilots use a Runway Condition Assessment Matrix (RCAM) to calculate their ...
For rigid pavements, design the pavement to resist a standard flexural stress of 2.75 MPa at the bottom of the cement concrete layer according to the LEA design procedure Calculate the single wheel load with a tire pressure of 1.50 MPa that would require the same pavement structural cross-section, this is the Derived Single Wheel Load (DSWL)
Aircraft bridges must be designed to support the heaviest aircraft that may cross them, or that will cross them in the future. In 1963, a taxiway bridge at O'Hare International Airport, one of the busiest airports in the world, was planned to handle future aircraft weighing 365,000 pounds (166,000 kg), but aircraft weights doubled within two years of its construction.

Meanwhile, the southern-most runway, 7R/25L was shifted 55 feet (17 m) to the south to prepare it for the additional width of the Airbus A380 and add a parallel taxiway between the adjacent runway. Runway 7R/25L reopened on March 25, 2007, and the taxiway was completed in 2008.
