Variables taken into account: CBR value and Poisson ratio of subgrade soil, load, tire pressure and type of landing gear. The only variable not included is the \"coverage\" which depends on the load repetition and is taken into consideration through a percentage of thickness required, but does not enter directly into the computations. The program is valid for CBR values not greater than 12, because of limitations from theory. As part of design parameters analisys, the influence of each variable into thickness determination is shown for three different types of landing gears.
