The L1 & L2 chart covers much of the Pacific Coast, including western portions of Washington, Oregon, and Northern California. Chart scale varies from 5 to 20 nm per inch. Published on the FAA's standard 56-day cycle. Available both as a one-time purchase or as a subscription, this is a low-cost, high-value resource that no instrument-rated pilot should risk flying without.

The least expensive way of getting these charts I have experienced so far. I fly a C182 Skylane. Order early and have them mailed!
