the 1 in 60 rule back in the day; times have changed
I still use it in B737 TR training when asking the students what their drift angle might be in various cross winds. They look aghast, yet they've come from spam cans. What are they teaching these days. Basic physics doesn't change with time.
Recently had a pilot student ask me what a sextant was ?
Could be an incestuous relative and get you into a heap of trouble.
I know this is a slight drift, but amusing. In the early days of LNAV & NAT tracks one guy, when inside the NAT system, called up to say he had an FMC failure. It was daylight VMC and he was west bound. ATC asked if he could see an XYZ a/c 1000' above him and possibly 5nm ahead. Yes they could. Well he's going to the same airport as you so follow him. Job done.
