Final answer:
The procedure when a holding pattern is specified in lieu of a procedure turn includes entering the hold at the holding fix and maintaining it until clearance is given for the approach. Standard right-hand turns are made unless instructed otherwise, following the chart's specific courses and timings.
Step-by-step explanation:
When a holding pattern is specified in lieu of a procedure turn, the procedure is as follows: The aircraft is expected to enter the holding pattern at the holding fix and maintain the hold until clearance is received for the approach. The holding pattern serves as a course reversal and is used to lose altitude or delay the aircraft before starting the approach. Holding patterns have standard right-hand turns unless depicted with left-hand turns on the chart. The pilot must adhere to the specified inbound leg course, turn directions, leg lengths, or specified timing as depicted or instructed by ATC. Understanding how to enter and fly a holding pattern effectively is a critical skill for pilots navigating busy airspace and approaching airports that require time for sequencing or additional space for safety reasons.
