Abstract

Input/steering mechanisms and aircraft control systems are provided. In an embodiment, by way of example only, an input/steering mechanism is provided for use with an aircraft control system. The input/steering mechanism includes a yoke that includes a hub, an alphanumeric keyboard, and a first grip surface. The alphanumeric keyboard is disposed on a face of the hub and is adapted to receive a manual input from a user and to transmit an output signal to the aircraft control system in response to the manual input. The first grip surface is formed on an outer periphery of the hub and is contoured to correspond with one or more fingers of the user, the first grip surface is formed such that a thumb of the user is positioned to rest in proximity to at least a portion of the alphanumeric keyboard when the one or more fingers grip the first grip surface.
