Landing Gear Wheel Load
Calculate the main landing gear wheel load, P_wheel = (W·f) ÷ n, from the aircraft weight W (N), the fraction of weight carried by the main gear f (typically ~0.90-0.95, the nose gear carries the rest) and the number of main gear wheels n. This load is the starting point of airport pavement design: it is the force each wheel transmits to the pavement, governing the required thickness and strength of runways, taxiways and aprons. Modern aircraft spread their huge weight over multi-wheel gears (4, 6 or more wheel bogies) precisely to reduce wheel load and pavement damage. The concept links to the ACN/PCN system (Aircraft/Pavement Classification Number) for compatibility checks, and to the equivalent single-wheel load (ESWL) that converts a real multi-wheel gear into one equivalent wheel for design. Enter the aircraft weight, the main gear fraction and the number of wheels.

Carga por roda do trem de pouso
A carga por roda do trem de pouso principal é P_roda = (W·f) ÷ n, a partir do peso da aeronave W, da fração desse peso suportada pelo trem principal f (tipicamente 0,90 a 0,95, já que o trem de nariz suporta o restante) e do número de rodas n do trem principal. Essa carga é o ponto de partida do dimensionamento de todo o pavimento aeroportuário: é a força que cada roda transmite ao pavimento, e dela dependem a espessura e a resistência exigidas das pistas, taxiways e pátios. As aeronaves modernas distribuem seu enorme peso (um Boeing 777 ou Airbus A380 pesa centenas de toneladas) em trens com múltiplas rodas — bogies de 4, 6 ou mais rodas — justamente para reduzir a carga por roda e, com isso, a agressão ao pavimento; espalhar a carga em mais rodas permite operar em pavimentos menos espessos. O conceito se conecta diretamente ao sistema ACN/PCN (Aircraft/Pavement Classification Number), o método internacional pelo qual se verifica a compatibilidade entre a aeronave e a capacidade do pavimento (uma aeronave com ACN maior que o PCN do pavimento não pode operar sem restrições), e ao conceito de carga de roda simples equivalente (ESWL — Equivalent Single Wheel Load), que converte a configuração real de múltiplas rodas em uma roda única de efeito equivalente, simplificando o cálculo da espessura do pavimento. Informe o peso da aeronave, a fração no trem principal e o número de rodas.

Accelerate-Stop Distance Available (ASDA)
Calculate the Accelerate-Stop Distance Available, ASDA = TORA + stopway, from the Take-Off Run Available (TORA) and the stopway length. ASDA is one of the four declared distances and has a critical safety role: it is the distance available to accelerate to the decision speed (V₁) and, if the pilot aborts the takeoff (engine failure or other), still stop safely. The stopway is a paved (or adequately strong) area beyond the runway, able to bear the aircraft in an emergency stop, not used in normal operation. Unlike the clearway (for the airborne aircraft), the stopway is for the aircraft on the ground, braking. ASDA is decisive in the balanced field length concept: the point where the distance to continue takeoff (one engine out) equals the distance to abort and stop defines V₁ and the required runway length. Enter the TORA and the stopway length.
