Yup, I gotta give you that one! In fairness to those who would have no plausible way of knowing, in Canada (but
not the U.S.), "DAR" stands for Design Approval Represnetative, a Transport Canada Aircraft Certification Delegation. Were I to be in the U.S. it would be "DER".
And no, I certainly don't claim to be qualified to give instructors instruction on instructing! I just remember the terrible time that I had remembering those (few, at the time) acronyms on how to fly a plane. I could eventually remember VOR, NDB, and DME (ususally 'cause I was too lazy to say or write the whole thing), and then came GPS, and my mind was big enough to hold that too. But then someone said GUMPS, and I'd be halfway along downwind not taking time to put the wheels down, while I was trying to remember if GUMPS was for downwind and HASEL for stalls, or the other way around! It was easier to just use the checklist printed for the plane, and remember good airmanship, and it all seemed to work out fine!
But, Intructors, if the acronyms help the new pilots, by all means!
