Understanding entry restrictions, how must the ICAO 45/180 procedure be entered?

• A. Only from the outbound track
• B. From all directions without limit
• C. From specified entry sectors relative to the inbound track
• D. Only from the inbound track

Answer: (C)

The ICAO 45/180 procedure, often related to holding patterns, requires that entries be made from specified sectors relative to the inbound track. This means that pilots must be aware of their position concerning the designated inbound course to follow the proper entry procedures. The reason that specified sectors are necessary is to ensure that the entry into the procedure is executed without compromising the integrity of airspace and maintaining safe separation from other aircraft. This structured approach helps pilots identify the most efficient and safe entry path into the holding pattern while adhering to air traffic control instructions. The other potential choices do not align with the requirement of specified entry sectors. Allowing entry from all directions without limit would create a higher risk of safety incidents, and limiting entry solely from the outbound track, only from the inbound track, or any other non-specified direction would not provide the necessary structure for safe and efficient operations.
