When may you use a parallel entry into holding?

The correct answer is when you are within the 110-degree offset sector. This scenario is aligned with standard procedures for entering holds, which dictate the various types of entries based on your aircraft's course in relation to the holding pattern.

In a parallel entry, you initially fly a track that is parallel to the holding pattern's outbound leg, allowing you to manage your approach to the entry more effectively. The use of the 110-degree offset is critical because it provides the necessary angle that allows you to set up for the maneuver without excessive deviation and helps ensure compliance with maximum hold entry standards.

The 30-degree offset would typically indicate a direct entry into the holding pattern, and angles less than 70 degrees may not justify a parallel entry unless specific operational conditions apply. Greater than 180 degrees offset does not allow for a parallel entry since your aircraft would already be positioned to effectively make a teardrop or direct entry instead. These parameters help pilots execute holding patterns efficiently while maintaining safe navigation practices.
