For an ATC clearance to hold east of the ABC VORTAC on the 090 radial with left turns, what is the recommended procedure to enter the holding pattern?

The recommended procedure for entering a holding pattern in this scenario is a parallel entry. In the given situation, the holding pattern is established east of the ABC VORTAC, with the aircraft to hold on the 090 radial and making left turns.

To execute a parallel entry, the pilot initially flies a heading that is parallel to the holding pattern's outbound leg (in this case, the 090 radial). Following this, the pilot will turn away from the hold, allowing the aircraft to track away from the fix for a short distance before making a turn to intercept the inbound track. This method is often utilized when the aircraft approaches the holding pattern from an angle that is roughly 90 degrees away from the outbound leg, making it the most efficient and logical entry method for this scenario.

The choice of parallel entry takes into account the need to maintain a stabilized approach to the hold, enhancing safety and ensuring that the aircraft enters the holding pattern accurately. This technique helps in managing aircraft separation and maintaining situational awareness for pilots.
