Methods and apparatus disclosed herein may facilitate the evaluation of time-correlated operational data associated with a mobile platform more effectively by presenting the relevant data in ways that are relatively straightforward to interpret and more favorable to the identification of potential root causes. In some aspects, the methods and apparatus disclosed herein may facilitate the evaluation of multiple systems simultaneously at different points in time to study the initiation and evolution of one or more faults across one or more systems. In various embodiments, the methods and apparatus disclosed herein make use of graphic user interfaces containing synchronized elements such as two-dimensional plots, fault timelines, alert timelines and status information to facilitate diagnostics of mobile platforms.
Tailplanes (24) and empennages (16) for aircraft (10) are disclosed. An exemplary tailplane (24) disclosed includes a stabilizer (30) having a fixed shape and an elevator (32) movably secured to the stabilizer (30). The elevator (32) is movable from a neutral position relative to the stabilizer (30). The stabilizer (32) and the elevator (32) define an airfoil cross-sectional shape (38) having a positive camber when the elevator (32) is in the neutral position. The positive camber of the airfoil cross-sectional shape (38) may facilitate movement of the elevator (32) during some flight conditions. Also disclosed are tailplanes (24) having camber distributions that vary along the spans of the tailplanes (24).
A composite material includes a honeycomb layer with top and bottom sides. The honeycomb layer includes a plurality of walls defining a plurality of cells therein. A first adhesive layer is disposed adjacent to the top side of the honeycomb layer. A second adhesive layer is disposed adjacent to the bottom side of the honeycomb layer. A third adhesive layer is disposed adjacent to the first adhesive layer on the top side of the honeycomb layer. A first composite layer is disposed adjacent to the third adhesive layer on the top side of the honeycomb layer. A second composite layer is disposed adjacent to the second adhesive layer on the bottom side of the honey comb layer. At least the third adhesive layer comprises viscous properties that discourage the creation of channels within the first composite layer when co-cured.

A door for an aircraft includes a first panel (58) divisible into at least two first slats (64-70) that are releasable connected to one another, a first tensioning cable (100) attached between the at least two first slats, and a first tensioner (124) connected to the first tensioning cable and being operative to apply a first tension thereto, thereby permitting the first tensioning cable to hold the at least two first slats together to form the first panel and to release the first tension in the first tensioning cable upon occurrence of a release action, thereby permitting the at least two first slats to dissociate from one another so that the first panel fragments.
