The Honeywell "Smart Runway" system (formerly RAAS), is one of the most incredible safety programs in recent memory. All an "add on" to EGPWS (GPS direct to EGPWS required).
In recent history, would have kept Comair from taking off on inappropriate runway, Delta landing on taxiway at ATL, Continental landing on taxiway at EWR, and would have helped/prevented AA at Jamaica.
But with today's economic climate, few airlines will expend funds for non-mandated equipment.
Sad......
