What is a significant factor in holding pattern entry?

The significant factor in holding pattern entry is the aircraft's current heading relative to the holding pattern. This is crucial because it determines the most efficient and safe method for entering the hold. When an aircraft approaches a holding pattern, the pilot must assess their current heading and how it relates to the orientation of the holding pattern.

Properly entering the holding pattern requires understanding which type of entry is needed—standard (right turns), non-standard (left turns), or a direct entry. If the aircraft is aligned with the inbound leg of the hold, a direct entry can be performed. Conversely, if the aircraft's heading is more than 90 degrees off the course to the hold, a teardrop or parallel entry may be necessary.

While the altitude of the holding pattern and the aircraft's speed can influence overall performance and safety considerations, they do not directly impact how one enters the pattern. The time spent in the pattern generally relates to how long the aircraft remains in the hold rather than the mechanics of entry. Thus, the current heading is the most significant factor for achieving a smooth and safe entry into the holding pattern.
