One Dash 8 crash in twenty years. How many were saved by GPWS in that time? The 15 SPIFR accident aircraft did not have the benefit of GPWS. If they did the result would have been different. SPIFR is not the issue!
The technology is here and it is time the CAA made it mandatory for all Air Transport IFR aircraft. Operators who can't afford TAWS because of capital resources should be shut down. The cost of wiping aircraft and people out is very high.
