Old 744 Forum

Greetings,

as you guys are so patient, I want to return some feedback on a regular basis, that is: a log of the latest additions to PSX's electrical equipment (in black font the components that are already implemented, in colored font the latest additions).

No worries: Most of the details on this equipment list don't need to be learned by the pilots, they are mainly for those interested in engineering.

For those new to the forum: PSX is under development, the current versions are unfinished non-public Alpha versions. Sadly, the final release date cannot be predicted yet.


Cheers,

|-|ardy



Edit:
The equipment list is obviously completed meanwhile. All entries are in black font. The beta version is finished. I'm working on the manual. This time it's going to be a colored PDF book. Below is the amount of pages that are finished. I'll update this number from time to time to provide some sort of feedback of the progress.

600



Edit 2:
Finished. Coincidentally, with cover and everything, it has exactly 600 pages. I swear this is pure coincidence.
