Preflight briefings are a must. It’s not only common sense; obtaining basic information related to an IFR flight is required under 14 CFR 91.103, including “weather reports and forecasts, fuel requirements, (and) alternatives available if the planned flight cannot be completed.” This by no means covers everything, and thanks to popular demand (and recent adjustments in the rules), it’s largely up to us to get what we need.
Online self-briefings and in-flight weather have become the primary method for many pilots. With all the electronic resources available, we seldom have to deal with Flight Service directly. If you choose not to, however, you’ll need to keep track of what you’ve read, and what you take with you.
