The Electronic Kit Bag (EKB) is a computerized, portable pilot “kit bag” that accepts input data, manipulates said data, and outputs solutions. The EKB consists of standard and state-of-the-art computing parts and peripherals, interfaced for maximum utility. The central operating program of the device assesses the relationships of input data through a logic based, three-dimensional decision-making algorithm. Data output is utilized either directly by the user, by the user through an aircraft system, or directly from the EKB to an aircraft system or autopilot.
