Hello all,

I just returned from California and found that SD worked well for normal VFR flight planning with the exception of frequency listings.

For example, Santa Barbara (KSBA) has separate frequencies for Clearance, Ground, Tower, Departure, E. and W. Approach as well as ATIS and UNICOM.  SD labels three of these frequencies and the rest it lists as "ON ADMIN".   Other airfields have frequencies with no labels (KOXR for example).  SD also fails to list Pt. Magu NAS which is the approach control for several SoCal airstrips.

I'd like to know where SD gets its frequency information and if it is possible to send in updates and/or corrections.

Thanks. This bug in our USA data has already been identified and fixed ready for the next chart update cycle. These happen every 56 days in the USA.
