jos nieswaag Posted January 9, 2022 Share Posted January 9, 2022 I have a problem with the correct display of the ND and PFD screen. At the right start I get the following picture: ND: TCAS fail and MAP error no GS, no TAS. Actually no information at all no route etc, etc. PFD: No horizon and other information . What do I need to do to make this work correctly? Link to comment Share on other sites More sharing options...
mmerelles Posted January 9, 2022 Share Posted January 9, 2022 You need to align the IRS system to make the displays come alive. -You need AC electricity going first (from APU or GPU) -Then turn both IRS knobs to NAV position on the top overhead panel -Then enter the GPS_L or GPS_R position as reference pos POS INIT on the FMC I highly recommend you to watch some COLD & DARK 737 tutorials available on youtube Link to comment Share on other sites More sharing options...
