Approaches

Question 1

Initial Segment

Answer 1

• Initial Approach Fix to Intermediate Fix
• 1000 ft of obstacle clearance
  Primary Area: 4 NM either side, 1000 ft of clearance
  Secondary Area: 2 NM extending from primary area, 500 ft of clearance decreasing to 0
• Descent gradient: 250 ft per mile is optimum, 500 ft per mile is maximum

Question 2

Intermediate Segment

Answer 2

• Intermediate Fix to Final Approach Fix
• 500 ft of obstacle clearance
• Descent gradient: 150 feet per mile is optimum, 318 ft per mile is maximum

Question 3

Final Segment

Answer 3

• Final Approach Fix or glideslope interception to Missed Approach Point or Decision Height
• 200+ ft obstacle clearance (300 for circling approaches)

Question 4

Missed Approach Segment

Answer 4

• Missed Approach point or DH onwards
• Obstacle clearance increasing to 1000 ft

Question 5

Circling Procedures

Answer 5

• Circle to land on different runway than approach
• Fly at or above circling minimums
• Remain within applicable Visual Maneuvering area, which has 300 ft obstacle clearance
• Must used missed approach procedure for original approach flown

Question 7

CAT I ILS

Answer 7

• 200 ft above TDZE
• 1/2 SM Advisory vis

Question 8

CAT II ILS

Answer 8

• 100 ft above TDZE
• 1/8 SM Advisory Vis
• DH based on radio altimeter indication

Question 9

CAT III ILS

Answer 9

RVR value, no DH

Question 10

ILS Approaches

Answer 10

• Descent should not be attempted before 1/2 scale deflection
• Aircraft should be in approach configuration upon reaching FAF
• Must go around if full scale localizer deflection or full scale up deflection
• If lose glidepath, can descend to MDA

Question 11

LPV

Answer 11

• Localizer with Vertical Guidance
• Requires WAAS-3 equipped GPS

Question 12

RNAV Obstacle Clearance Initial Segment

Answer 12

• Primary area: 2 NM either side
• Secondary Area: 1NM additionally
