Vague DP

The DP out of LGA reads:

"DEPARTURE PROCEDU Rwy 4, climb to 600 before proceeding westbound.
Rwy 13, climb to 800 before proceeding westbound. Rwy 22, climb to 1400
before proceeding westbound. Rwy 31, climb to 1200 before proceeding
southbound."

It seems kind of vague to me. Is it implied that you're supposed to
climb on runway heading? Also, what does "westbound" mean? Any heading
between 180 and 360 clockwise? But if that's the case, runway heading
is already "westbound". It all seems a little nebulous for IFR stuff.

Yes.

Towads the sunset.

Any heading
between 180 and 360 clockwise?

Or any heading from 225 through 315 degrees.

But if that's the case, runway heading
is already "westbound".

Runway 4 heads westbound? Runway 13 ?

It might be nebulous for VFR, but not necessarily for IFR. Whatever they
want you to clear might be very noticeable on a VFR sectional. Have you
checked?

My take is that this is an obstacle DP. You follow whatever clearance you
are given, but climb on runway heading, or other heading given by ATC,
provided it isn't westbound or southbound. I would climb on runway heading
to the altitude given, then turn to whatever heading was assigned or would be
required by the clearance. It is a little vague in that it doesn't
specifically say runway heading, but it lets you fly pretty much any heading
as long as it isn't south or west.

You are reading the obstacle DP. The La Guardia Nine Departure shows that
earlier climbs may be OK if you are not heading westbound.

Earlier "turns", Ron?
