IFR use of handheld GPS

Simply said, ifr use of vfr gps is not in the spirit of the far's.

So that is why I asked the original question. Does IFR use of a
drugstore-bought calculator or a wris****ch or a sextant fall under the
same category? If not why is it different? Do you use IFR pencils to
copy your clearance on IFR paper? I'm getting silly, but in all
seriousness, where do you draw the line?

Does the FAA have a set of regs written for a sextant? They do for the GPS.

Where can that set of regs be found?

But do they have regs regarding handheld GPS units? There may be TSOs
and other stuff for panel mounts, but that has nothing to do with
handhelds. Just because both have the term "GPS" in the name doesn't
connect them in a regulatory sense. You might as well call your
handheld an "automatic sextant". Then is it okay to use while IFR? I
bet there are no regs for those.

can you use a CD player while IFR? of course you can.

Can you use a PED while IFR? of course you can.

Nah, a real pilot would cross correlate the waypoint off of two VOR's,
then use the DG (that precesses mightily), set from the compass (that
swings a lot in the turbulence) to navigate to the said waypoint, so
when he gets back to the base he can give the neophytes next to the
water cooler a blow by blow account of the whole heroic deed......

Doug, you sound like one of the few on this group who actually know how to
fly.

In navigator training back when we actually used a sextant, whenever
our mission called for legs using celestial navigation ATC would give
us a celnav clearance. This allowed us much more airspace than a
"direct" clearance as celestial nav was less precise than other methods
of navigation. On missions which required students to use only ded
reckoning, the pilot would also ask ATC for a celnav clearance in order
to have the freedom to manuever (i.e. wander) off the direct line to
the next turnpoint. Thus, when ATC sends you direct to a point, they
expect you to be pretty darn close to staying on the direct course to
that point. If you decide that your going to use a watch and compass
(dr) or pull out a sextant and you wander significantly off that
straight line and stray into restricted airspace--guess who's going to
get violated?

Yes, but probably not as less precise as you think!
