Good morning, San Francisco!

From 2am today (local), the airspace in San Francisco will look very different.

There are some substantial changes to the airspace around San Francisco that came into effect at 2am local time this morning.

This is particularly important as Class B affects both Part 107 and recreational (Part 101) drone pilots. The good news is that the volume actually got smaller, but as most of the reduction sits over the Golden Gate National Recreation Area National Park, you might not actually be able to make use of the 300 billion cubic feet that just got handed back to you!

Removing everything but Class B airspace, SFO now looks like this:
