Parallel Operations

Question 1

Mode 1

Answer 1

Independent parallel approaches
No radar separation

Question 2

Mode 2

Answer 2

Dependent parallel approaches
1000ft vertical/3nm separation

Question 3

Main difference between independent and dependent parallel approaches

Answer 3

Independent = relies on procedures for separation
Dependent = relies on radar to provide separation

Question 4

One runway used for approaches and one runway used for departures

Answer 4

Segregated parallel operations

Question 5

One runway used exclusively for departures and other used for approaches and departures

Answer 5

Semi mixed operations

Question 6

Aircraft departing in same direction from parallel runways simultaneously

Answer 6

Simultaneous instrument departures

Question 7

ATS surveillance system separation minima between ac using published instrument approach procedures

Answer 7

Dependent parallel approaches

Question 8

ATS Surveillance system separation minima between aircraft without prescribed approach procedures

Answer 8

Mode 1 independent

Question 9

No Transgression Zone

Answer 9

Mode 1 no radar separation therefore used to determine if ac deviates too far from ILS localiser course

Question 10

Mode 2 Dependent Parallel Approach - distances on same runway and different runway

Answer 10

Radar separation - 3nm on same runway
Radar separation - 2nm different runways

Question 11

What ICAO Doc is used for parallel runway ops

Answer 11

ICAO Doc 9843

(Decreasing numbers like towards touching down)

Question 12

What would the controller do if an aircraft enters the NTZ

Answer 12

Issue control instructions for the threatened aircraft on adjacent approach to go around and direct away from

Question 13

Segregated operations how much should tracks diverge on departure

Answer 13

30 degrees

Question 14

Semi Mixed

Answer 14

One rwy for dep
One rwy for dep and arrivals

Question 15

Segregated ops

Answer 15

Mode 4
One rwy for app
One rwy for dep

Question 16

Interception of localizer angle

Answer 16

Not more than 30 degrees

Question 17

Missed approach track must diverge by at least

Answer 17

30 degrees

Question 18

Minimum aircraft equipment required for parallel approaches

Answer 18

Full ILS/MLS capability

Question 19

Minimum separation for mode 2 approaches on same ILS and adjacent ILS localisers

Answer 19

Same ILS = 3nm
Different ILS = 2 nm

Question 20

ATC are required to identity aircraft within how many nm of DER

Answer 20

1nm

Question 21

Simultaneous parallel departures

Answer 21

Departures from both runways at once
