Hi All,

When studying the chart supplement for KSBD, I saw the following:

SOCAL APP/DEP CON 125.5 (SW–N) 127.0 (N–NE) 134.0 (NE–S) 135.4 (S–SW).

What do (SW–N), (N–NE) etc mean?

Thanks in advance for the answer!!!

Thanks, that's what I thought too, but that was until I read in the CAT 7 page that for a westward flight path to El Monte, we are supposed to contact SoCal Approach on 127.0, which according to the chart supplement is for N-NE.

Why is the N-NE frequency used for a westward journey??

Best,

For example looking at our route of flight from KSBD to KEMT you would see that to transition the KONT Class C airspace from the North East you would contact SOCAL approach on 127.00.

The above is with reference to making a transition of the KONT airspace. For KONT the chart supplement shows the following:

SOCAL APP/DEP CON 125.5 (SW–N) 127.0 (N–NE) 134.0 (NE–S) 135.4 (S–SW)

Thanks Kullery, my bad... I missed that sentence on the CAT 7 page.
