What if you are VFR over a cloud layer? There are lots of times

Well, there are other, more traditional, methods that are really
pretty essential if you're going to do that. 1 in 60 rule, for
instance. Determinging drift from aircraft ref points and
celestial bodies, that sort of stuff.

Last time I checked celestial navigation wasn't in the PP
requirements and use of a VOR was.

I know, but going vfr on top is kinda heavy territory for someone
with a fresh ppl anyway.

How many know the 1/60 rule?

Me. But I'm old :-)



You probably also know what a four way range is and how to time oil drips
to see if it;s too thinck to start up!
