IFR out of Big Bear

[Shinjo B]

Hi ... a little confused about trying to fly IFR out of BIg Bear. The only that seems to exist is an RNAV. Does that mean if I'm not GPS capable then I can't fly IFR out of Big Bear? Or am I missing something?

That's exactly how I would read it. the OKACO1 departure is RNAV for IFR but also considered an Obstacle departure procedure. The OKACO waypoint is also on an IFR chart as 25 mile NW of the the PSP VOR on V386. So you could take off from runway 8 and if you meet the minimum climb rate to 8000', you could intercept the waypoint on V386 and would have completed the OBSTACLE part of the departure.

Total guess here: since you can triangulate the OKACO waypoint that probably removes this from being /A usable. Although you could hand draw a radial on a chart from the Coyote VOR (NXP at the Twentynine Palms airport) at 073 and what looks to be 21NM away. But it's not charted that way so you're not official.

can't fly this DP without RNAV. If it's socked in and you don't have RNAV, you ain't goin', short of rolling your own procedure.

if it's vmc, you could climb in vfr conditions to the minimum instrument altitude.

Keith pretty much has it.

You cannot file the ODP unless you are RNAV capable. This doesn't mean that RNAV is required to depart L35, just that if you don't have RNAV you have to depart using your own terrain separation to the minimum IFR altitude.
