What is one method of entering a hold in aviation?

Entering a hold in aviation can be accomplished through several methods, but one of the most straightforward and commonly used methods is the direct entry. In this method, the aircraft approaches the holding pattern directly from the inbound course. The pilot makes a 180-degree turn to initiate the holding pattern and then flies outbound for a specified time or distance before turning back to rejoin the inbound leg of the hold. This technique is favored for its simplicity and effectiveness, allowing for a smooth transition into the holding pattern.

The other methods, while valid, may require more complex maneuvers or adjustments. For instance, a loop entry involves a more extensive turn to the right or left, and a circle entry typically means circling around the holding fix before entering the pattern. A square entry, although less common, involves a series of turns that might not be as direct. Direct entry minimizes confusion and helps maintain spatial awareness, making it the preferred choice in many situations.
