FAA Instrument Flight Instructor (FII)IFR Procedures and ApproachesMedium
An instrument student is practicing an RNAV (GPS) approach. The approach plate shows a 'Terminal Arrival Area' (TAA) surrounding the airport. What is the primary purpose of a TAA?
- ATo provide radar vectors for aircraft transitioning from en route to the instrument approach.
- BTo provide a seamless transition from the en route structure to the terminal environment with minimum altitudes.
- CTo define an area for course reversal maneuvers when a procedure turn is required.
- DTo designate a mandatory reporting point for all IFR aircraft entering the terminal area.
Show answer & explanationAnswer & explanation
Correct answer: B. To provide a seamless transition from the en route structure to the terminal environment with minimum altitudes.
A Terminal Arrival Area (TAA) is designed to provide a seamless transition from the en route structure to the terminal environment for RNAV approaches, eliminating the need for procedure turns or course reversals and specifying minimum altitudes within defined sectors.
Why the other options are wrong
- A. TAAs are designed to reduce the need for radar vectors by providing published routes and altitudes.
- C. TAAs typically eliminate the need for course reversals within their defined sectors.
- D. TAAs define airspace and altitudes, not mandatory reporting points.
Terminal Arrival Area (TAA)
A defined area that provides a seamless transition from the en route structure to the terminal environment for RNAV approaches, specifying minimum altitudes.
- Associated with RNAV (GPS) approaches.
- Eliminates the need for procedure turns or course reversals.
- Provides obstacles clearance and minimum altitudes within sectors.
- Depicted on RNAV approach charts.
Memory trick: TAA: Transition, Altitudes, Avoid reversals.
