Do the copilots get trained to set the radar up correctly? Windfarms don't appear overnight but I have encountered at least one that hadn't been added to the mapping. The first thing that usually gets erected before a windfarm is set up is a single mast - again the mapping often lags behind the reality.
Our TD takes just over a minute so the length of time spent on the final run in and letdown into the blind arc is probably less than 3 minutes or so and the whole area would have been cleared in a turn beforehand. We can modify out TD tomake 180 turns if required because the radar can see that area - this gives more flexibility when letting down into bays or in busy shipping lanes. Bristows came up with a plan to put a tail mounted radar on a S61 - maybe that's why they lost the contract
You could fit the S92 with a 360 radar, it's just that no-one wants to because they are so 'forward looking'!!!!
You are right about the homers though - the Griffin in Cyprus has the fit we need in UK but the IPT keeps getting in the way. We can do double PLB homings though and it is a quarterly requirement for pilots to practise them - can you say the same?
