  1. TRU failure

    WillCat_91 replied to neas1982's topic in PMDG 737NGX | 737NGXu
    Hi, I was testing the simulation of the electrical system using the 737 technical site as reference. Especially I was focusing on TRU failures and I noticed the same behavior in the simulation as reported above : it seems the disconnect relay has been missed. Because I cannot see any effect with a TR1 failure on G/S capture with auto-pilot(s) engaged. So the electrical system as simulated might need some tweaks..... Also a TR1 failure leads to both DC Amps and DC Volts beeing reported to zero, but the mesure point is supposed to be in the DC BUS 1 for TR1, so Volts should not be zero as soon as the relay is closed and compensed by TR2 and TR3. Argh, I went to PMDG to test the accuracy of the electrical system.... and I canno't reproduce what is cited in the FCOM about DC sides isolations and on the 737 technical site. Sad. Best regards.
