Oh Didley D - thankyou thankyou thankyou.
There also seems to be a fascination with the fact that D&D only provide AutoTriangulation and that its not always there where you need it. So bloody what. The times I have called D&D for traing at lowish level and what they do is make you sqawk. They then talk to a local radar unit, who then see you. If that fails they get you to turn. And then they hand you to that controller......My point being, they are there to help in anyway possible whether it be to just sound calming on the R/T to doing all your map reading for you.
When the chips are down, pilots tend to forget even the most easiest tasks such as pick up the map, find who is the nearest radar unit - pick out the frequency and dial it. However we ALL know 121.500.
Use it use it use it folks! If the gods upstairs can't cope with it - it ain't ya problem!
