Marked on the chart as "Caution Intensive Flight Training," these designations indicate airspace better known as, Practice Areas.
Practice Areas dominate much of the LA Airspace. Each has concentrated traffic, specific frequencies for use and altitudes; but their boundaries are not charted. In this section, SCAUWG shows you the approximate locations so you can plan safer flights.
While flying through Practice Areas being on frequency, being situationally aware via communicating your position and intended flight path, and becoming aware of other traffic in the area is critical. This is particularly true when flying through areas noted for either waivered, or allowed aerobatic flight. "Flight Following" alone is not sufficient when the traffic movement in these areas is much less than predictable!
A list of 13 Los Angeles Basin Practice Areas is accessible on the reverse side of the LA TAC Chart near the VFR Transition Routes. It details the frequencies to use, and the altitudes to be aware of. However, you will still need to know the approximate boundary information; and to fulfill that task, SCAUWG has you covered!
A few presentations have evolved to outline where the Practice Areas are in the Los Angeles Basin. All of the areas designated are from original work done by Al German CFI, on behalf of the SCAUWG.
Two types of presentations are outlined below. Select your preference; a PowerPoint or a .PDF file.
