RAAS description and operation
 
Looking for descriptive and operational material for the commercial aviation (smart landing) version of the Runway Awareness and Advisory System (RAAS).
Insufficient detail on Honeywell website; unable to access technical descriptions for RAAS or EGPWS.

In particular what is the basis for a long landing alert, sensor input, reference data base, method of calculation, accuracy, and installation options.
An example Crew FCOM would help; i.e. guidance for use and thence a basis for training.
Technical facts please, no discussion or 'I think ...', however well reasoned AFAIR could help.

The description given on page 61 onwards in https://www51.honeywell.com/aero/com...0-4241-000.pdf
appears to be from the manufacturer and is dated 2011 with an update in 2013.
Specific details of the RAAS operation start on page 100.
