Specialty Displays and Visual Indicators

Specialized displays and visual indicators are specialized or proprietary products and accessories related to displays and visual indicators. There are many different types of specialized displays and visual indicators. Examples include a head up display, visual approach slope indicator, brake indicator, and pneumatic visual indicator. A head up display is a type of specialty display that provides means of projecting information directly into a human's visual field. A visual approach slope indicator is a type of visual indicator that provides special lights on the side of a runway to assist pilots with staying on the glide slope for the runway. A brake indicator is a type of visual indicator that signals either a parking brake is engaged or that brake fluid is low. A pneumatic visual indicator is a type of visual indicator used as an accessory to provide a quick and reliable, visual indication of the status of a pneumatic system and detects the presence or absence of a pneumatic signal. Other specialized displays and visual indicators are commonly available.

Specialized displays and visual indicators are produced in a variety of ways. A head up display is a high-resolution, color camera that includes a compact variable field of view lens with motorized iris. Auto iris control is provided via driver circuitry located in the camera. Generally, power consumption on a head up display is 12V DC and 3W. A visual approach slope indicator provides the basic means to transition from instrument flight to visual flight for landing. A visual approach slope indicator is a configuration of signal lights starting at the landing threshold and extending into the approach area a distance of 2400-3000 feet for precision instrument runways and 1400-1500 feet for nonprecision instrument runways. Some visual approach slope indicator systems include sequenced flashing lights that will appear to the pilot as a ball of light traveling towards the runway at high speed (twice a second). A brake indicator assembly includes a stop indicator sign assembly housing onto which an electrically driven retraction/extension mechanism is positioned. When the brake lights of a vehicle are activated, a brake indicator sign is extended out of the cavity by the electrically driven retraction/extension mechanism and when the brake lights of a vehicle are deactivated the brake indicator sign is retracted into the cavity by the electrically driven retraction/extension mechanism. A pneumatic visual indicator system enables a wide angle of visibility and offers contrasting color combinations for positive identification of a pneumatic system failure. Specialized displays and visual indicators can be designed and manufactured to meet most industry specifications.

Specialized displays and visual indicators are used in a variety of applications. Examples include the use of a head up display. A head up display is specifically developed for applications where an optimal field of view is required such as fighter- or trainer aircraft operation. A brake indicator is an important factor in the safe operation of industrial machinery and consumer automobiles. Uniform Federal Accessibility Standards (UFAS) provide some guidelines for specialized displays and visual indicators.
