VERTICAL TRANSITION CURVES ALONG AIRPORT RUNWAYS

SUI RACCORDI VERTICALI LUNGO LE PISTE AEROPORTUALI

Vertical transition curves on airport runways are always circular curves of a sufficiently ample radius to maintain within acceptable limits the stresses on the undercarriage caused by gradient variations, and also to respect required visibility conditions. Runways, more so than roads, require that the gradient variations along a transition curve are as gradual as possible. To this end ICAO standards specify that the variation of gradient between two consecutive levels must not be greater than 1.5% for class a, b and c runways, and 2% for class d and c. Based on the argument that a more extended transition than that provided by circular curves would improve the stability of aircraft ground movements, this article illustrates the application of a sinusoidal transition curve to gradient changes along a runway.
