Tim, some of the other guys are playing around with you a little bit, but
I'll spell it out for you since I started it.

That reg says what you have to have onboard, but does not say what you
will or must use for navigation. IFR course tracking is a performance
standard. You must stay on the assigned course. How you do that is not
specified or regulated. What you use to fly that course is not specified
or regulated. Only that you fly that course, somehow.

So, you may use dead reckoning if you want to, radar vectors, celestial
nav (right!), or even (the crowd is on the edge of their seats in
anticpation) a tuna sandwich. The tuna sandwich must not, however, be
placarded "VFR only."

So, it is perfectly acceptable to look at your handheld GPS, see that it
says 237 degrees and 16 minutes to FUBAR,

There are GPS units that use minutes? I'd have thought them all to be
decimal format.



dead reckon by flying a 237 heading, and monitor your progress by
reference to the handheld GPS.


A good pilot will have an idea of the wind and correct for it.
