Weather reports and forecasts

In plain English

Weather decisions must be based on approved weather reports and forecasts — official sources (or those approved in the ops specs). A pilot may use other current weather information only to supplement, and may make local observations when no report is available.

Key points

• Use approved/official weather sources for go/no-go and planning.
• Supplement, don’t replace, with unofficial information.
• Document the basis for weather decisions.

Common pitfalls

• Launching on a non-approved app forecast alone.
