I started 3 people off last summer in one group training for IMC, all have fallen by the wayside for various reasons, hopefully not my teaching, but I heard from one of them last week , they all convinced themselves that as their ac had no ADF, they didnt want the expense to use a club aircraft to finish the rating, I organised a cheapish PA 28 140 and they still didnt want to finish. So there we are, they also all convinced themselves that they would never use it !
