10 - Approach Procedures

Question 1

What are the five segments of the flight phase between leaving the ATS route structure and the landing?

Answer 1

• The arrival segment
• The initial approach segment
• The intermediate segment
• The final approach segment
• The missed approach segment

Question 2

What are STARS?

Answer 2

Standard arrival routes that cover the arrival segment and connect the ATS routes to the initial approach segment.

Question 3

For a facility providing track guidance, what is the NDB / VOR / ILS system accuracy?

Answer 3

NDB: +/- 6.9°
VOR: +/- 5.2°
ILS: +/- 2.4°

Question 4

For a facility not providing track guidance, what is the NDB / VOR / ILS system accuracy?

Answer 4

NDB: +/- 6.2° (-0.7)
VOR: +/- 4.5° (-0.7)
ILS: +/- 1.4° (-1)

Question 5

Why is speed the most significant factor affecting the size of the protected area?

Answer 5

Because speed directly affects turn radius.

Question 6

What are the 5 aircraft categories (based on their threshold speed)

Answer 6

A < 90
90 < B <120 (+30)
120 < C < 140 (+20)
140 < D < 165 (+15)
165 < E < 210 (+45)
H: Helicopters

Question 7

What is the MSA (Minimum Sector Altitude)

Answer 7

It is the lowest altitude you can fly to guarantee the MOC (Minimum Obstacle Clearance) of 300 meters within a radius of 25 NM of the aerodrome’s homing facility.
