In version 5, now that the CRT MDF is incorporated into SSU, this set of steps isn’t necessary anymore. Setting up the MDU’s logic: Power should already be on for all of the CRT’s from the checklist. Press and hold the page key, which is the lower right soft key [PG] under the CRT, and the equivalent of the default Orbiter MFD menu screen will appear. Click on the page soft key to keep cycling through your choice of MFD’s. To select the MFD you want, use the soft key under the MFD acronym in the page menu. As an example, the commander 2 CRT should show A/E PFD information. Here’s how to get that. CRT power on --→click and hold PG soft key to see MFD selection menu--→click but don’t hold PG soft key twice--→click soft key under CRT in main menu---→click soft key under FLT INST(may need to click soft key under “up arrow” to get to FLT INST button)-→click soft key A/E PFD. This will result in seeing the ADI and compass rose on the commanders number two CRT (the right one).

Accelerate time as needed to about T minus 35 minutes or so. This will set you up for the final launch sequence.
