Worked Area per Machine
Calculate the area worked by a farm machine, A = field capacity × time, multiplying the effective field capacity (ha/h) by the available operating time (h). The result, in hectares, is how much the machine can cover in a shift — direct input for operational planning: how many hours (or days) are needed to complete the planting, spraying or harvesting of an area, and whether the machine fleet meets the agronomic window (the period in which the operation must occur). Undersizing the fleet delays critical operations and reduces yield. Enter the field capacity and the operating time.

Área trabalhada por máquina
O planejamento operacional de uma fazenda gira em torno de uma conta simples mas decisiva: quanto cada máquina consegue fazer no tempo disponível. A área trabalhada é A = capacidade de campo × tempo, o produto da capacidade de campo efetiva (ha/h — quantos hectares a máquina faz por hora, já descontadas as perdas) pelo tempo de operação disponível (horas de uma jornada). Uma máquina de 1,5 ha/h em 8 horas cobre 12 hectares. Essa informação alimenta as decisões mais importantes da gestão agrícola. Dimensionamento de frota: dividindo a área total da fazenda pela área que cada máquina faz por dia, sabe-se quantos dias (ou quantas máquinas) são necessários para concluir uma operação. Cumprimento da janela agronômica: cada operação tem um prazo ideal — plantar dentro da época recomendada (atraso reduz produtividade), pulverizar antes de a praga ou doença se alastrar, colher no ponto certo de umidade (antes que chuvas estraguem ou grãos caiam). Se a frota não cobre a área dentro da janela, há perda de produtividade ou de qualidade. Por isso fazendas grandes investem em máquinas de maior capacidade (barras mais largas, maior velocidade) ou em mais máquinas, e em turnos estendidos (trabalho noturno com GPS/autoguia). O cálculo também serve para orçar horas-máquina, mão de obra e insumos por jornada. É a ponte entre a capacidade técnica da máquina e o planejamento real da safra. Informe a capacidade de campo e o tempo de operação.

Field Efficiency
Calculate the field efficiency of a mechanized operation, Ef = (effective capacity ÷ theoretical capacity) × 100%, dividing the effective field capacity (area actually worked per hour) by the theoretical capacity (the one obtained with no time losses). The result, in %, measures how much of the time the machine actually works, as opposed to headland turns, refills, adjustments, travel and overlaps. Simple operations in large fields have high efficiency (80-90%); complex operations in small, irregular fields, low (60-70%). Improving field efficiency (larger fields, fewer stops) reduces costs. Enter the effective and theoretical capacities.
Effective Field Capacity
Calculate the effective field capacity of a mechanized farming operation, FC = (v × L × Ef) ÷ 10, from the working speed v (km/h), the effective working width L (m) and the field efficiency Ef (decimal). The result, in hectares per hour, is the area the machine actually works per hour, already discounting time losses with turns, refills and overlaps (efficiency). The factor 10 adjusts the units. It is central to mechanization planning: it sets how many machines and hours are needed to complete an operation (planting, spraying, harvesting) in the available window. Enter the speed, the width and the field efficiency.
Aircraft Apron Area
Estimate the total area of an aircraft apron, A = number of positions · area per position, from the number of parking positions and the average area each occupies (m²), including the aircraft, surrounding safety clearances and service/circulation lanes. The apron is the airport area where aircraft park for passenger boarding, cargo and ground services. Area per position depends strongly on aircraft size: a code-F position (such as the A380) needs a square tens of metres on a side plus safety margins, occupying several thousand square metres; regional aircraft positions are much smaller. Apron sizing is one of the biggest area consumers on an airport's airside and a high investment (reinforced pavement for parked and maneuvering aircraft loads). The simplified calculation (positions × average area) gives the planning order of magnitude; detailed design positions each gate per the aircraft mix, operation type (nose-in with pushback, or self-maneuvering) and terminal geometry. Enter the number of positions and the area per position.
