Electronic non-linear aircraft dynamic parameter display

Abstract

A method and apparatus is disclosed for displaying a dynamic parameter of an aircraft, the apparatus comprises a display unit receiving a display signal and displaying a scale that changes dynamically and non-linearly in accordance with a selected display algorithm, the display unit further displaying a pointer pointing to said scale in accordance with a reading of said dynamic parameter, thereby emphasizing a range of said reading of said dynamic parameter.

Description

technical field [0001] The invention relates to the field of aircraft instrumentation, more precisely, the invention specifically relates to an aircraft dynamic parameter display. Background technique [0002] The measurement and display of aircraft dynamic parameters are key issues for correct control, maneuvering and confirmation of aircraft position and speed. [0003] Measuring aircraft flight altitude and vertical speed with barometers and other devices is well known and is a well-established technology built on principles that have remained relatively unchanged since the first deployment of altimeters and vertical speed indicators (VSIs). [0004] In contrast, "modern" altimeter displays have undergone four distinct generations of development. [0005] The earliest modern altimeter display was the "three-pointer" circular altimeter analog display, which incorporated three concentric reading hands facing the same dial. The flight altitudes of 100 feet, 1000 feet and 1...

AI Technical Summary

Problems solved by technology

Both forms of display share a serious disadvantage in that they employ a fixed scale that requires a trade-off between resolution and scale range

In other words, a large scale is easier to read but has a relatively small display range, while a small scale achieves a good range but sacrifices legibility
