Abstract
Official abstract text for this publication.
A method of positioning landing gear of an airplane is provided that includes providing the landing gear including a shock strut, a truck beam operatively pivotally connected to the shock strut, first and second interconnected links operatively connected to the truck beam and a third link extending between the shock strut and the first and second links with the third link pivotally connected to the second link at a third pivot. When the landing gear is commanded to a lowered position, the third pivot is positioned in a first position to support a taxi mode, a take-off mode and a landing mode if the landing gear is operational and in a second position to support an alternate landing mode if the landing gear is not fully operational. When the landing gear is commanded to a raised position, the third pivot is in the second position to support a stow mode.
