Definition
The cross-country flight planning step in which the pilot gathers all charts, publications, weather products, performance data, and reference materials required to plan and conduct the flight before any route or fuel calculations begin.
Plain English
Before planning a flight, the pilot collects everything they will need to plan it properly — current charts, weather reports, the aircraft's performance numbers, airport information, and any other references the flight will require.
Context Anchor
Seen at the start of preflight and cross-country planning, before choosing a route, checking weather, estimating fuel, or reviewing airport details.
Why Pilots Care
Skipping or shortcutting this step is a common cause of in-flight surprises — outdated charts, missing frequencies, unknown runway lengths, or unchecked weather. Having the right material in front of you before planning starts is what makes the rest of the planning reliable.
Intuition Check
Do not read this as just casually gathering supplies. In this FAA context, the “material” means the current flight information and planning tools a pilot needs to make safe, legal, and complete preflight decisions.
Example Sentence 1
Before plotting the route to her destination, she began assembling necessary material: the current sectional, the Chart Supplement, and the latest weather briefing.
Example Sentence 2
Assembling necessary material before every cross-country flight helps ensure all required information is available during the trip.
