The Flight Safety Foundation (FSF) produce some free useful guides to prevent CFIT and avoid ALAR incidents.
It takes, the first time about five minutes to evaluate the potential CFIT risk to a proposed operation and identify the threats. For those interested, completing the CFIT analysis for the Norfolk island ditching may, perhaps provides some insight. It may just surprise you. The FSF link:-
FSF – CFIT analysis.
Should you have the spare moments, the FSF ALAR exercise ran against the Norfolk incident will again, provide some very interesting data. The FSF link:-
