GPWS is telling me not to sink during a perfectly normal ILS approach. Does anybody know how to make it less sensitive or something so it doesn't bother me?

The "Don't Sink" warning is a takeoff warning only. It was designed to alert a pilot of a negative rate of climb during takeoff - specifically during an engine failure while doing the engine failure profile. This is an error in some code either in FSX or in the CS model.

The way I fixed the problem was to go into sounds in the FSX folder and look for this "don't sink" callout and I just renamed it .old so it no longer sounds during an approach. Others have made more ingenious fixes and if you go back in the 727 area, you will find what they did.
