Junior Chuck Yeager Check Capt asks "when will you start your descent?" Line Capt replies "100 miles." Check Capt furiously checks: his 3 times table, deceleration, weight adjustment, QNH adjustment, position of the VOR in relation to the runway.... gives up eventually and asks " How do you get 100 miles?" Very senior line Capt nochanantly replies "Oh I always go down at 100 miles.'
