When should the timing begin for the first leg outbound in a nonstandard holding pattern?

The correct timing for the first leg outbound in a nonstandard holding pattern begins when the aircraft is either over the holding fix or abeam the holding fix, whichever occurs later. This approach ensures that the timing for the outbound leg appropriately reflects the aircraft's position relative to the holding fix, maintaining consistency in the holding pattern regardless of the specific layout of the fix itself.

In practice, beginning the outbound timing at the later of these two points accounts for any variations in approach or drift that may occur as the aircraft enters the holding pattern. It helps to provide a standardized method that enhances safety and efficiency while navigating through nonstandard holding patterns. By adhering to this timing rule, pilots can ensure that they are following proper procedures, which is essential for smooth operation and communication with air traffic control.

The other options are less optimal as they may not accurately reflect the guidelines for timing in a nonstandard hold, potentially leading to inconsistencies in holding pattern management.
