Answer 37

• Re-intercept the Final Approach Course

Question 38

What should you do if you have full scale CDI deflection after the FAF but prior to the DA or MAP?

Answer 38

• Turn to re-establish and track the Final Approach Course to the non-precision MAP WHILE climbing to the missed approach altitude

Question 39

How can a Missed Approach Point (MAP) be defined?

Answer 39

• Station passage
• Timing
• DME
• DME backed up by timing

Question 40

What are the differences between a PAR w/o GS and an ASR approach?

Answer 40

A PAR w/o GS approach can have you handed over to a final approach controller whereas an ASR only uses one controller

A PAR w/o GS is more precise than an ASR so it will have lower minimums

The ASR use the airport surveillance radar the entire approach whereas the PAR w/o GS uses the PAR Radar on final

Question 41

For a PAR, when can you begin your descent?

Answer 41

Wait to begin your descent until you hear the controller say “on glidepath””

• Threshold
• Threshold markings
• Threshold lights
• Runway End Identifier Lights (REIL)
• Visual Approach Slope Indicator (VASI)

What obstacle clearance is provided by the circling minimums?

Answer 44

A basic minimum of 300’ of obstacle clearance at the MDA within the circling area

Question 45

What are the immeadiate priorities when executing a Missed Approach?

Answer 45

1. Establishing a positive rate of climb
2. Turn the aircraft (if required) to intercept the missed approach course or designated heading
