Aernov Posted February 2, 2021 Posted February 2, 2021 UFC Brightness knob currently works as "on/off" switch, without the ability to gradually adjust brightness of UFC displays (panel lighting works fine). Attached screens show that UFC displays maintain max brightness regardless of BRT knob position. Also, there are little glowing bits of display symbology visible on UFC keyboard (one is marked on screenshot, there are others, appearing in different places on keypad, but they appear only in specific UFC modes, which I do not remember/use often enough). And one more question - should EHSD map mode symbology color change be applied to all MFD pages, or just to EHSD page itself? If it should, is there another way to change MFD symbology color (without going to EHSD-MAPM-color and back)?
Skopikus Posted February 2, 2021 Posted February 2, 2021 (edited) As I remember (I'm at work right now, sorry) In right lower corner there is "CONT" buttons - they will help you to change contract. In Left lower corner there is GAIN button - that gains brightness of text(not sure) and on upper left corner there is "day/night" buttons that changes (guess it?) Day/night mode. Do not know what "SYM" button does. Hope that will help. Edited February 2, 2021 by Skopikus
Aernov Posted February 2, 2021 Author Posted February 2, 2021 These control MFD screen parameters, and SYM changes symbology brightness. I was talking about UFC and BRT knob to the right of main UFC display.
RAZBAM_ELMO Posted February 3, 2021 Posted February 3, 2021 Can you confirm you are attempting to control the HUD brightness or the UFC brightness. The knob on the UFC labelled BRT controls the brightness of the UFC lights. below the UFC and above the standby ADI and CRS switch you have another row of switches and knobs. The left most knob adjusts the HUD display brightness. The right two control the brightness and contrast of the NAVFLIR. Know and use all the capabilities in your airplane. If you don't, sooner or later, some guy who does use them all will kick your ass. — Dave 'Preacher' Pace, USN.
Vakarian Posted February 3, 2021 Posted February 3, 2021 UFC brightess knob does either 100% illumination or 0%, there is nothing in-between. That is what the OP is trying to say
Aernov Posted February 4, 2021 Author Posted February 4, 2021 Yes, I am talking about the knob that controls UFC displays (and maybe ODU, I don't remember) Other BRT knobs (MFDs, engine panel, HUD and HUD video, panel and instrument backlight and floodlights) are working correctly.
