EVS Camera

What it is

Two possible installations: the MAX-VIZ EVS-1500, IR image only, or the EVS-2300, which adds a color image alongside the IR one. A Long Wave Infrared camera is mounted facing forward under the right-hand nose compartment, feeding the MFD as a visual aid in reduced visibility. Selected on and off from the EDCU KITS → CAMERA tab; a video test pattern shows for about 5 seconds after power-on, then an OK message, then an IR image after about 20 seconds total.

The camera automatically recalibrates its IR sensor (NUC) every 4 minutes — a 1-second screen blank with CAL displayed — which can be inhibited from the same EDCU page if needed. It's self-anti-iced with internal heaters whenever powered on, fed from Main Bus 1 (REPU 1 Channel A), a bus not shown on the DC ELEC synoptic page.

Display and field of view

Shown full-size on the MFD VIDEO page, or as picture-in-picture on VIDEO or DMAP pages. Brightness/contrast adjust via the VIDEO page bezel buttons — on the EVS-2300, the IR and color channels have independent brightness/contrast controls. Field of view (Narrow/Wide) is selected from the PFD EVS menu or the DCP EVS button, and on the EVS-2300 that selection applies to both the IR and color image together. Zooming is available via PFD controls or the DCP.

Selecting a field-of-view change removes the SVS from the PFD — the two compete for the same display space. SVS has to be manually reselected afterward (DCP SVS button, or the SVS bezel key on the PFD SVS menu). Since the EVS image itself is not shown on the PFD, the PFD EVS menu's BRT/CNST bezel keys have no effect.

Limitations

Do not use the EVS image for takeoff, landing, or navigation. It is an obstacle-awareness aid only — the display may not have the accuracy or fidelity to base takeoff, landing, or navigation decisions on.
