I have to ask Crab, did you get your ATPL via the CAA dispensation for the QHIs and 38 group or did you actually sweat?
The reason I ask. I was working out of Sumburgh, bumbling along in a 61 with a former service colleague who was a QHI, hadn't sat the exams as he was given the dipensation, and was then the training Capt for the operation. He asked, "How does an ILS work?" I told him I was busy and this wasn't a check ride. He looked sheepish and told me it was the only safe environment he could ask the question as he had never had to study for the exams.
