Precision instrument flying

I was just reviewing the new Elmira One departure procedure. I think
the government has let GPS go to their heads. Unless I'm reading it
incorrectly, it specifies the initial heading out to TWO decimal places!
The procedure is pretty trivial as it basically says to fly runway
heading to 4000 feet, but it is specified as below, using R24 as an example:

Climb via heading 242.40 to 4000, thence...

I'm not bad on heading control, but no way I can fly 242.40, or even
242.4. I'm pretty happy if I can fly 241 - 243! :-)

That's a charting issue. The source is required to state values to those
precisions. Chart makers are supposed to show them to the whole degree.

It then says to "Expect clearnace". Oh, and I guess I won't be departing
rwy 28 because I can't maintain "minimum clib of 594' per NM". I could
probably maintain a minimum *climb*, but that's not what it specifies.

Yes, a pretty sorry excuse for a chart. I think it is pretty new as it
wasn't in my last set of plates. Maybe they will get it right on the
next edition.

Only if it is brought to their attention. There is an email address on the
TPP booklet to report charting errors, and I have found them to be very
responsive.

Using Jepp plates, one can be sloppier as that chart only calls for a 242°
Heading :-)

Blimey, you're one of those advanced pilots I keep hearing about. I'm still
working on: "That way, over there, see?"

Well, I started out with N, E, S and W.
I then moved up to N, NE, E, SE, S, SW, W, NW.

It wasn't until I got my instrument rating that I REALLY thought about
flying a heading to the nearest degree or thereabouts. It isn't that
hard in smooth conditions once you learn to use trim correctly.
However, it is still pretty much impossible for me in turbulence. You
sort of average the heading you desire, but rarely can you hold within 2
degrees in the bumps.

However, this chart just made me laugh when I saw the headings they listed!

You're probably one of those people who round off those pesky 778 foot DH's
to 780 too :-)

How'd you know? Please, don't tell the FAA!
