When should outbound timing begin in a holding pattern?

In a holding pattern, outbound timing is crucial for maintaining the proper duration of each leg of the hold. Timing should begin when the aircraft is over or abeam the fix. This is because it allows for precise control of the time spent in the hold, ensuring that the aircraft follows the recommended delay and remains organized within the airspace structure.

Starting the timing at this point ensures that the outbound leg is flown correctly and that the inbound leg will also be the appropriate distance away from the fix when the aircraft returns. Keeping track of timing from the fix helps pilots plan their maneuvers effectively and align with air traffic control requirements.

Beginning timing at the start of the outbound leg might cause discrepancies, as it could lead to either an under or over-extension of the holding pattern, which can potentially create traffic conflicts. Similarly, timing when wings are level inbound doesn't align with the standard operating procedures for holding patterns, and timing after flying for 1 minute does not account for the variable durations required based on specific traffic or procedural needs.
