In an altitude and vertical speed indicator for aircraft, an altitude indicator includes a graduated scale vertically mobile past a fixed marker and a vertical speed indicator includes a pointer rotatable about the point of intersection of a straight line segment through the fixed marker and a straight line segment through the pointer and pointing towards the mobile scale. The angle defined by the fixed marker and the pointer is representative of the vertical speed value.
A device for enhancing altitude awareness in an avionics display is disclosed. The device includes an altitude indicator that displays a current altitude on the avionics display. A scrolling display of altitude levels is displayed with the altitude indicator on the avionics display. The scrolling display includes a plurality of scaled numbers that represent predetermined intervals of altitude levels surrounding the current altitude. The scrolling display also includes a non-numeric graphic construct that is displayed adjacent the plurality of scaled numbers. The graphic construct has first and second substantially mirror-image portions that are positioned on first and second opposing sides of the plurality of scaled numbers. A controller causes the altitude indicator to display the current altitude on the avionics display. The controller also causes the scrolling display to display the predetermined intervals of altitude levels surrounding the current altitude and to vary the graphic construct consistent with the predetermined altitude levels that are displayed. A vertical speed indicator may be superimposed upon the scrolling display.
A graphical display or presentation of lateral ANP/RNP information for RNAV environments. The display may also be adapted to present aircraft data for monitoring the vertical flight performance of an aircraft under RVSM.
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.
A graphical display of a nonlinear scale emulating the view of a mechanical drum gauge. The nonlinear scale may be used for the display of aircraft flight data including airspeed, altitude, heading, and other aircraft data suitable for presentation on a nonlinear scale. The nonlinear scale may scroll to display current aircraft data.
A graphical display of a vertical speed indicator showing "fly-to" and "no-fly" commands on the periphery of a vertical speed indicator during TCAS traffic or resolution advisory conditions.
