Question 9

What obstacle clearance does a T-VASIS or PAPI provide?

Answer 9

• Obstacle clearance of at least 11 metres, above a 1.9 degree slope, within 7.5 degrees either side of the centreline, for 5 nm or 7 nm if equipped with an ILS.

Question 10

What eye height above the threshold would be expected on a T-VASIS showing 3 lights fly up?

Answer 10

0 to 7’

AD 1.1 : 6.1.1

Question 11

How is a ‘Calvert’ or distance-coded centreline precision approach lighting system implemented?

Answer 11

• An extended runway cetnreline out to 900 m;
• Cross bars spaced at 150 m intervals;
• Where the runway can accommodate Cat II/III approaches, the last 300 m will include two rows of red lights either side of the centreline.

AD 1.1 : 5.12.3

Question 12

What eye height above the threshold would be expected on a T-VASIS showing on slope?

Answer 12

49’

AD 1.1 : 6.1.1

Question 13

What approach angle correlates to a PAPI four whites indication?

Answer 13

Greater than 3.5 degrees

AD 1.1 : 6.1.2

Question 14

What length are runway centreline markings?

Answer 14

30 m long, followed by a 30 m gap.

AD 1.1 : 4.5.8

Question 15

‘Distance to go’ signs may be installed on what runways?

Answer 15

• On LAHSO runways, a distance to go sign may be installed where the pilot may have difficulty seeing the intersecting runway. They indicate the distance to the hold short line in metres;
• On military runways, distance to go signs are isntalled which indicate the remaining runway distance in feet.

AD 1.1 : 4.12.1

Question 16

What approach angle correlates to a PAPI four reds indication?

Answer 16

Less than 2.5 degrees

AD 1.1 : 6.1.2

Question 17

How are ICAO ‘A’ touchdown zone markings implemented?

Answer 17

• A main touchdown zone marking at 400 m from the threshold, or 300 m for runways less than 2,400 m;
• Three markings following at 150 m intervals;
• One or two markings preceeding the main touchdown zone.

AD 1.1 : 4.5.9

Question 18

Where a sealed portion of the runway is not available for normal operations (e.g. a stopway), how is it identified?

Answer 18

By a series of yellow Vee bars marked along its entire length.

AD 1.1 : 4.5.7

Question 19

How is a ‘Barette’ precision approach lighting system implemented?

Answer 19

• An extended runway cetnreline out to 900 m, with sequenced ‘running rabbit’ flashing lights;
• A cross bar at 300 m;
• Where the runway can accommodate Cat II/III approaches, the last 300 m will include two rows of red lights either side of the centreline.

AD 1.1 : 5.12.3

Question 20

What markings indicate a temporarily displaced threshold?

Answer 20

Primarily, a series of inverted ‘V’ markings at the threshold. Other markings may be used to indicate the unservicable area, including unservicable cone markers (red and white), orange safety cones, white crosses, or white centreline arrows.

Flashing white strobes may be used instead of V-bar markers.

AD 1.1 : 4.5.4 - 4.5.5, 5.2.2

Question 21

What eye height above the threshold would be expected on a T-VASIS showing 1 light fly up?

Answer 21

25 to 41’

AD 1.1 : 6.1.1

Question 22

What approach angle correlates to a PAPI three whites indication?

Answer 22

Approximately 3.3 degrees

AD 1.1 : 6.1.2

Question 23

What will you see in terms of runway lighting as you approach the end of the runway?

Answer 23

• At 900 m to go, centreline lighting changes from white to alternating white and red;
• At 600 m to go, runway edge lights change from white to amber (precision approach Cat I/II runways);
• At 300 m to go, centreline lighting changes to red.

AD 1.1 : 5.4.3, 5.6.1

Question 24

When are the ILS critical and sensitive areas protected?

Answer 24

• Where the ceiling is above 600’ or the visibility above 2000 m, there is no protection;
• Where the celing is at or less than 600’ or the visibility at or less than 2000 m, but equal to or above the Cat I minimums, the critical area is protected except when a landing aircraft enters the critical area or when the approaching aircraft is outside the OM or 4 nm if there is no OM;
• Where the conditions are less than Cat I minimums, the critical area is protected when the arriving aircraft has passed the OM or is within 4 nm if there is no OM, and the sensitive area is protected when within 2 nm;
• Where the visibility is less than 550 m for a LLZ guided takeoff, both the critical and sensitive areas are protected until the takeoff is completed.

AD 1.1 : 3.3.1

Question 25

Runway boundary gable markers are spaced at what distance?

Answer 25

Not more than 180 m intervals when marking the runway strip.

AD 1.1 : 4.1.1

Question 26

What approach angle correlates to a PAPI on slope indication?

Answer 26

3 degrees
