1.2.2 Menu Selection

At a minimum, menu selections shall display the video controller firmware version, display control parameters, and display test controls.

The display shall provide a maximum of two modes of lighting, integral adjustable high intensity backlighting for white and Night/NVG lighting.

Maximum luminance shall be at least 1,000 nits (292 fl) for CTFL only backlights or 343 nits (100 fl) for CTFL/LED/Coated panel hybrid displays. The display shall be dimmable to NVIS-compatible level. The control button's backlighting shall be automatically adjustable over the luminance range.

The NVG lighting mode shall be accomplished through the use of an NVG compatible backlight technology. The Night mode/NVG backlight intensity shall be controllable via the front panel control.

Integrity of the data presented shall be such that no loss of function occurs during operation, with the probability of presenting Hazardously Misleading Information (HMI) less than once per 2,000 flight hours to ensure that no “dark cockpit” scenarios occur during operation. Primary navigation data shall be clearly legible in all ambient lighting environments, including full sunshine as defined in Section 3.3.6 of this specification.

The displays shall have sufficient resolution, uniformity, refresh rate, and update rate to present the data being displayed with no objectionable smear, jerking, or other artifacts. The displays shall be capable of automatically rescaling/sizing any of the input signals provided in this specification to the native resolution of the display.

1.3.1 Viewing

Characteristics

All indicators displayed (indicia, pointers, symbols, etc.) shall be completely visible from any eye position within the viewing envelope(s). The display shall produce symbols with maximum luminance of at least 300 nits.The minimum viewing angle shall be at least ± 80 degrees horizontal, and ± 40 degrees vertical from the Design Eye Point (DEP).

VGA:

shall support 1280x1024 pixel resolution at a 60Hz refresh rate, non-interlace VGA analog video.

shall support 800x600 pixel resolution at a 60Hz refresh rate, non-interlace VGA analog video.

The display shall handle a refresh rate ranging from 56 to 81 Hz.

1.3.3 Defects

LCD defect acceptable ratios shall be in accordance with the guidance provided in ISO 13406-2.

1.3.4.1 General

The luminance, contrast, and viewing angle requirements of the following subparagraphs shall be met when measured from the DEP. Luminance and contrast values at end-of life shall be as defined in MIL-HDBK-87213 Rev A Tables I and II as described in the following subparagraphs.

1.3.4.1.1 Illumination

and Glare Source Luminance

The display shall adhere to the requirements as found in Table I of MIL-HDBK- 87213 Rev A (sunshine ambient in a bubble canopy, indoor enclosed cabin, and dark) for both Diffuse illumination and glare source. The verification shall be by demonstration and by analysis.

1.3.4.1.2 Contrast

The display shall adhere to the requirements as found in Table II of MIL-HDBK- 87213 Rev A (required contrast in worst-case ambient). The verification shall be by demonstration and by analysis.

1.3.4.2 NVIS

Minimum Luminance

Under night lighting, with the display brightness set at the lowest usable level with normal symbology, the display symbology shall be adequately visible. To achieve acceptable viewing in dark conditions, the minimum white symbol luminance when measured in a dark ambient must meet the requirements in MIL-STD-3009 (current revision).

1.3.4.3 NVIS

Radiance

Display areas of a specified color (excluding the dark or OFF state) shall have a radiance uniformity of less than 0.5 nit, per MIL-STD-3009 (current revision) for electronic and electo-optical displays (multi-color), Table III.a, across the utilized display surface when measured from the DEP. In no case shall luminance non-uniformity cause the maximum white symbol luminance anywhere on the usable display surface to go below the values previously specified.

1.3.4.4 NVG Mode

The displays shall adhere to the NVIS and NVG requirements as defined in MIL- STD-3009. In the NVG mode, the display shall be dimmable to a level that does not bloom the night vision goggles. MIL-L-85762A shall be utilized, in conjuction with MIL-STD-3009, to define the characteristics of the LCAC night vision goggles.

1.3.4.5 Dark Ambient

Contrast Ratio

The average white contrast ratio over the usable display surface shall be a minimum of 200:1 at the design eye position and 20:1 for any eye position within the viewing envelope.

Contrast Ratio

The average white contrast ratio over the usable display surface shall be a minimum of 6:1. When viewed from any eye position within the viewing envelope, it shall be no less than 3:1. This requirement applies when subjected to point source illumination levels up to 8000 fc.

1.3.5.2 Specular

Reflections

The total specular (or shiny surface) reflectivity within the viewing envelope shall be less than 0.5 percent IAW MIL-HDBK-87213.. Other non-emitting areas shall have a low reflectivity coating to minimize internal reflections. In no case shall the level of reflectivity and loss of contrast be sufficient to cause distracting or erroneous interpretation.

1.3.5.3 Diffuse

Reflectivity

The total diffuse reflectivity (or the reflection of light from an uneven or granular surface) as measured with respect to the designed eye position shall be no more than 0.8 percent.
