Course Profile, Your assetion that having the GS turned off was a cause of this crash is just wrong. It wasn't a primary cause. It wasn't even a contributary cause or else more aircraft would crash every time there was no GS available.
Aircraft land at airports all over the world every day using a visual approach without crashing. The PAPI was working perfectly and that is the main assistance the pilot needs for a visual approach, not a GS.
To go back to Jimjim's reference to a bank, would you expect the bank to use a mortgage calculator when all you are trying to do is withdraw $100 from your checking account? That is the equivilent to what you are suggesting here. Why would an instrument approach tool be needed for a visual approach?
