Chapter 10 Parallel Runway Operations

Question 1

What are the two basic modes of approaches?

Answer 1

Independent (mode 1) and dependent (mode 2)

Question 2

What are these modes of approaches independent/dependant on?

Answer 2

Radar separation

Question 3

What is done to all approaches in all weather conditions?

Answer 3

Radar monitored (not separation)

Question 4

On mode 1 and 2 approaches how long must be flown before localiser intercept?

Answer 4

1nm

Question 5

On mode 1 and 2 what is the max localiser intercept track?

Answer 5

30 degrees

Question 6

What is the minimum separation of parallel runways in mode 1 approaches?

Answer 6

1035m

Question 7

In mode 1 and 2 approaches how much must the missed approaches diverge by?

Answer 7

By at least 30 degrees

Question 8

How long must straight and level be flown before intercepting G/S in both mode 1 and 2?

Answer 8

2nm

Question 9

On mode 2 approaches what is the minimum rwy separation?

Answer 9

915m

Question 10

What is the minimum separation between aircraft in mode 2 approaches?

Answer 10

3nm if on same localiser and 2nm if on different localiser

Question 11

What is mode 3?

Answer 11

Simultaneous SIDs

Question 12

What are the requirements for mode 3?

Answer 12

• tracks diverge by 15 degrees

- must identified by 1nm from DER

Question 13

What is mode 4?

Answer 13

Where one runway is used for departures and the other used for landings (segregated parallel ops)

Question 14

What is the max intercept onto localiser in mode 4?

Answer 14

45 degrees

Question 15

What is the non transgression zone?

Answer 15

Area between the two normal operating zones

Question 16

Where does the NOZ occur?

Answer 16

From runway threshold to where you establish on localiser separation. Half a scale deflection wide

Question 17

Where does the NTZ occur?

Answer 17

Extends from runway threshold to point where 1000ft vertical separation is lost

Question 18

What is required if an aircraft enters the NTZ?

Answer 18

ATC intervention

Question 19

What is the minimum width of the NTZ? ****

Answer 19

610m

Question 20

When must wake turbulence separation be applied?

Answer 20

Space between two runways is less than 760m and/or if aircraft become within 1000ft or each other
