When are you considered established in a holding pattern?

Being considered established in a holding pattern is determined by how the aircraft interacts with the defined holding fix. Specifically, you are deemed established upon the initial passage of the holding fix. This is the point at which the aircraft has successfully crossed the reference point that marks the start of the holding pattern, enabling it to properly execute the maneuver as designed.

The essence of this definition is tied to the requirements and procedures set forth in instrument flying regulations. Upon the initial passage of the holding fix, the pilot can begin to configure the aircraft for the appropriate entry into the holding pattern, manage timing, and ensure altitude is maintained.

In contrast, simply flying at the holding altitude, departing the holding pattern, or being at a 30-degree offset does not qualify as being established in the pattern. These actions do not signify that the aircraft has crossed the holding fix and thus cannot fulfill the requirements for establishing in the holding pattern.
