Thanks Jim, I think its a great pity that this material has been lost from the public domain - we are now seeing the consequences of that and presumably must wait for the next fatal accident before its reborn.
Although you say that AVAD is optimised for overwater not overland, it still has considerable value overland (though EGPWS is probably better) and with correct operating procedures, does not produce nuisance warnings. SAR is not covered by JAR-OPS 3 and even if it were (as HHA is), that would be the sort of area where a National Authority could grant a dispensation to allow an inhibit switch for the fixed height call - just like our very own JSAR had. When inhibited, the AVAD CWP caption was illuminated so there was little doubt that the 100' call was off. But in reality it was rarely used as 100' is normally far too high for winching.
Do you think there is any chance of getting the advisory material back into circulation during the transfer to EASA OPS? The longer its left, the more aircraft there will be around that are not compliant and so the harder it would be to introduce.
And what to do about the 139? If we are correct that its not compliant, does anyone care enough to do anything about it?
