I wonder why they don't synchronize this with the Sectional publication
dates. The next San Francisco chart will come out in early September.

Sectional charts are updated during their 6 month lifespan via the
Aeronautical Chart Bulletin in the Airport/Facility Directory.


If the date of a change is optional, it would be better for pilots if the
change were synchronized, so that there would be fewer updates
for pilots to have to manually add to their charts. CDW recently
changed its freq also, it would have been nice if they had waited a
few months.


Frequencies are not changed on a whim, they're changed to correct a problem
somewhere. Delaying a change for a few months means putting up with the
problem for a few months. Updating a chart is easy.
