FAA Instrument Rating Airplane (IRA)IFR Procedures and ChartsEasy
A pilot planning to use a Standard Terminal Arrival (STAR) notices the chart states 'descend via' phraseology may be issued by ATC. What is the primary purpose of a STAR?
- ATo replace the need for an approach clearance at the destination
- BTo reduce pilot/controller workload by providing a standardized route and altitude transition from the en route structure to the terminal area
- CTo provide a mandatory holding pattern prior to landing
- DTo define the missed approach procedure for all runways at the airport
Show answer & explanationAnswer & explanation
Correct answer: B. To reduce pilot/controller workload by providing a standardized route and altitude transition from the en route structure to the terminal area
STARs are published to simplify clearance delivery and reduce communication by providing a preplanned route and altitude/speed profile from the en route environment into the terminal area, prior to being cleared for an approach.
Why the other options are wrong
- A. An approach clearance is still required after completing the STAR
- C. STARs do not inherently require holding unless charted separately
- D. Missed approach procedures are part of approach charts, not STARs
Standard Terminal Arrival Route (STAR)
A preplanned IFR route that simplifies clearance delivery from the en route structure to the terminal area, often with charted altitude/speed restrictions.
- Pilots must have the chart to accept a STAR clearance
- 'Descend via' means comply with all altitude restrictions unless amended
- STARs do not replace the approach clearance
Memory trick: STAR = Smooth Transition Avoiding Radio-chatter
