A terrain avoidance system, method and computer program product for reducing nuisance alarms. In a pressurized state of the fluidic chamber, the deformable cover is deformed such that it forms an inflexion point area within the deformed cover. A network address is input into the destination entry input device corresponding to an installation location of the destination entry input device. The deflection is absorbed by the shock absorber so that the anchor remains undeformed and the ground remains undamaged.
