Hello, Firstly sorry if this issue is already take into account. I am just going to buy FS2crew for PMDG777. I confirm that packs not switch auto by the FO during the pre-flight flow as expected (in voice or button control). I start the PF events in COLD & DARK configuration and I perform the preliminary pre-flight procedure with electrical power up (directly with APU or with a GPU) but without external ground conditioned air. But at 19 minutes, the FO does not carry out PACKS AUTO action between LIGHTS and FO FLIGHT DIRECTOR. Thx.
