Glide Distance
Compute the horizontal distance an aircraft (or glider) travels in an unpowered glide, d = altitude · glide ratio, multiplying the available height by the glide ratio (how many meters it advances per meter descended, equal to L/D). A glider with a 40:1 ratio at 1000 m reaches 40 km. It is the engine-out range and landing-circuit calculation. Enter the altitude and the glide ratio.

Distância de planeio
Se o motor parar, até onde o avião chega planando? A resposta é direta: d = altitude · razão de planeio. A razão de planeio (quantos metros a aeronave avança para cada metro que desce) é numericamente igual à sua eficiência aerodinâmica L/D. Um Cessna plana a ~9:1; um airliner a ~17:1; um planador de competição supera 50:1 — de 1000 m de altura, alcança mais de 50 km. O cálculo é vital em duas situações: estimar o alcance em pane de motor (e escolher para onde planar) e dimensionar o circuito de pouso. Curiosamente, a distância de planeio não depende do peso — só da aerodinâmica. Informe a altitude e a razão de planeio.

Aircraft Climb Time
Compute an aircraft's climb time, t = Δaltitude/rate of climb (ROC), dividing the altitude gain by the rate of climb (in ft/min or m/min). It estimates how long the aircraft takes to reach cruise altitude — used in flight planning, climb fuel burn and traffic separation. The rate of climb decreases with altitude, so the result is an average estimate. Enter the altitude gain and the rate of climb.

Film Thickness Ratio (λ)
Calculate the specific film thickness ratio (lambda), λ = h_min ÷ √(Ra₁² + Ra₂²), from the minimum lubricant film thickness h_min and the surface roughnesses Ra of the two contacting surfaces. The dimensionless result indicates the elastohydrodynamic lubrication regime: λ < 1 means direct asperity contact (boundary lubrication, high wear); 1 < λ < 3, mixed lubrication; and λ > 3, full separation of the surfaces by the oil film (full regime, long life). It is a key criterion in gear and rolling-bearing design. Enter the minimum film thickness and the surface roughnesses.
