Alex, condolences on the loss of your father, very sad to hear of his passing.
Your father was instrumental in clearing away the 'fog' that obscured much of the ATPL met syllabus when I attended BGS in the early 2000s, during my last years in the RAF at Brize Norton. He would use his wry sense of humour to lift the mood, when many of the classroom occupants were bucklng under the mental load of clmatology and similar. His approach to dealing with it all certainly made a difference for me.
Take care, fella.
