Abstract
A menu-driven, hand-held navigation and flight performance computer having a keyboard, display, and CPU. The display includes a menu region for displaying the names of navigation and flight performance functions, one or more parameter name regions and a data region. The keyboard includes a first cursor key for selecting among the navigation and flight performance functions on the menu portion of the display. The keyboard additionally includes a key for triggering the start of a specific function selected by the cursor key, a plurality of arithmetic operator keys, a plurality of number keys, and a conversion key for converting data from one unit of measure to another. A timer is included for upcounting and downcounting and for triggering the automatic shut-off of the computer after a specific period of time expires since the last keyboard entry. The CPU retains outputs of select programs to be used as default inputs to select subsequently executed programs. The computer generates sequential prompts for required inputs to programs, leaving the prompt and input display during the program.
