Meet Boeing 777
The 777 entered service in 1995 after development with input from major airline customers. Its broad cabin and two very large engines filled a space between the 767 and 747. The programme expanded through different fuselage lengths, range developments and engine choices.
The family name therefore covers aircraft with meaningful technical differences. A 777-200ER with several engine options and a 777-300ER are not interchangeable references. PMDG and FlightFactor also implement their own systems, so descriptions remain attached to each developer and version.

PMDG
The 777's flight-control logic is modelled explicitly
PMDG describes custom C*U flight-control logic with normal and direct modes, path and speed management, and artificial-feel modelling. The reviewed 777-200ER product also offers different engine families with their own indications and thrust behaviour. These are properties of the documented PMDG aircraft, rather than a blanket description of every 777 add-on.

Version history is useful technical documentation
FlightFactor's 777 change log publishes selected MCP and CDU dataref types and identifies remote-instrumentation and CDU API documentation supplied with the product. It also records fixes to restored control states. For cockpit builders, the installed version and its supplied API material are part of the reference, not just the aircraft's product name.
