Leads to arcs/radials are based on what rate of turn?
ANSWER One-half standard rate
GCA PROCEDURES / PRECISION RADAR APPROACHES (PARs)
What is the primary difference between a PAR and an ASR?
ANSWER: You will be provided with glidepath information on a PAR.
What should your AOB be in the GCA pattern?
ANSWER: 30 degrees AOB in the initial pattern, 20 degrees AOB when dirty, and no more than 10
degrees AOB on final.
How are rate of descent and AOA controlled on the glidepath?
ANSWER: Rate of descent is controlled with power and AOA is controlled with nose attitude.
What information must the pilot repeat during any GCA approach?
ANSWER: Headings, altitudes, and altimeter settings until instructed otherwise
SURVEILLANCE RADAR APPROACHES (ASRs)
Are recommended altitudes automatically provided in an ASR?
ANSWER: No, only if requested by the pilot.
What AOB is used in the pattern and why?
ANSWER: 30 degrees AOB. The controller needs to know your rate of turn for alignment purposes.
For a GCA, what information must the controller provide the pilot prior to final approach?
1. Type of approach (precision or surveillance)
3. Location of MAP (surveillance only)
4. Advisory to perform landing check (USN/USMC controllers only)
5. Missed approach instructions and lost comm instructions
6. Position information and heading changes as necessary to keep you on course
What are the lost comm time intervals for a PAR?
ANSWER: 60 seconds in pattern, 5 seconds on final
