Photo No. 1.General view of main MFD installed into the standard slot for Gr 4V Display.
MFD displays data from Weather Radar, TCAS, TAWS (ÑÐÏÁÇ) and navigation systems.
Main technical characteristics of MFD:
- MFD screen size 111 x 83 mm.
- Display resolution 320 x 240 pixels.
- viewing angle: vertical ±25° horizontal ±50°
- brightness 250 cd/m2
«Kontur-NIIRS» Ltd. is the original equipment manufacturer (OEM) of MFD.
MFDs are installed into the standard slots of «GROZA» Weather Radar displays.
Main Display À813-0409.2 and additional Display À813-0409.3 are connected with data cable for data transfer
from main Display to the additional Display.
The tests were aimed to evaluate MDF compliance to the performance characteristics of «GROZA» Weather Radar in
accordance with its operating manual; MFD allocation; controls handiness; radar image quality at MFD screen.
MFD À813-0409.2 and À813-0409.3, are installed instead of standard Gr 4V and Gr 4D displays of «GROZA» Weather Radar.
Preliminary flight tests on October 29-30, 2004 onboard «NPP MIR» Ltd. IL-18 No. 75713 aircraft were successfully passed.
Using MFD with «GROZA» Weather Radar essentially improves work convenience for the aircraft crew.
