Abstract
The disclosed lightweight portable ladder provides a stable platform that can nest in close proximity to helicopters, aircraft and other machines to facilitate enhanced access for inspection and maintenance. The ladder consists of a stepped unit connected by hinged means located near the top a support unit and means to hold the units in a fixed orientation. The distance from the hinge point to the bottom of the support unit is longer than from the hinge point to the bottom of the stepped unit. The hinge point may be located some distance below the top of the stepped unit, in which case the upper portion of that unit will be cantilevered with respect to the hinge point. The location of the hinge point can be tailored for specific aircraft and applications so as to provide an optimized fit when the ladder is positioned for use.
