Interesting to see this subject has been covered in September's edition of a popular magazine beginning with P (in case that counts as advertsing
)
It is interesting that the "expert" FIs seem to support practising calls to D and D and dont get "hung up" at all about admissions of being lost. Whilst I would say this, I thought they have the balance exactly right.
It still puzzles me why some of us seem to have this huge thing about pilots saying they are "lost". You call D and D either because you are lost, a bit lost, or want a training fix. I suspect it is all pretty irrelevant to them, they tell you where you are, and point you in the right direction if you need that as well.
