Standard Instrument Departures (SIDs) and Standard Instrument Arrivals (STARs) are published procedures which include route information and may include tracking, level, speed and other requirements and restrictions. SIDs and STARs are becoming increasingly complex and differences in design and phraseologies are creating misunderstandings between pilots and controllers as to the intent of the controllers’ instructions. A significant concern is misunderstandings whether level restrictions shall be complied with or have been cancelled.
IFATCA Policy is:SID and STAR design and use should be globally harmonized. Phraseology and corresponding message sets shall be developed to easily indicate whether published vertical profile is to be followed or not. Airspace, procedures and charting should be designed and implemented based on the latest ICAO provisions regarding SIDs and STARs. The result shall be that ATC clearances are unambiguous and their intended effects are achieved. Controller workload shall not increase beyond an acceptable level. |
