Given all of the options available for many of the payware aircraft, is there a resource that identifies, by airline and/or by specific aircraft, configuration information? That is - which engines, which avionics, etc.

I don't believe a comprehensive, publicly available database exists that accurately documents the detailed configuration of every individual aircraft.

The primary reason is that aircraft manufacturers provide operators with extensive configuration and optional equipment selections. Each airline customizes its fleet according to its operational requirements, regulatory environment, and budget. While the engine type generally remains unchanged throughout the aircraft's service life, engine control software and performance packages may be updated over time.

In addition, aircraft are continuously modified through service bulletins, manufacturer upgrades, Supplemental Type Certificates (STCs), and airline-specific retrofit programs. It is not uncommon to encounter airframes that have received upgrades to avionics, radios, flight management systems (FMS/FMC), displays, or other cockpit equipment that differ significantly from their original delivery configuration.

As a result, the most reliable source of configuration-specific information is often a pilot or maintenance engineer with direct operational experience on that aircraft within a particular airline. Even then, fleet standardization is not guaranteed, as aircraft may undergo major retrofits during their operational life, resulting in substantially different cockpit layouts or system configurations compared to sister ships.

To manage these fleet variations, many airlines maintain aircraft-specific "Differences Data" or "Differences Training" documentation. These documents identify equipment and configuration differences between individual aircraft and are provided to flight crews during pre-flight briefing or through the airline's operational documentation to ensure crews are aware of any relevant variations before operating the aircraft.

Only really does engines and sometimes seat config, does show the history of an aircraft and it's MSN.

Not sure this fully answers your question but can do some of it...

For avionics fit I just search for the reg (or airline/type) on airliners.net and choose "Flightdeck" as the category, usually throws up useful info.
