75 to 94’
AD 1.1 : 6.1.1
What obstacle clearance does a T-VASIS or PAPI provide?
- 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.
AD 1.1 : 6.1
What eye height above the threshold would be expected on a T-VASIS showing 3 lights fly up?
0 to 7’
AD 1.1 : 6.1.1
How is a ‘Calvert’ or distance-coded centreline precision approach lighting system implemented?
- 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
What eye height above the threshold would be expected on a T-VASIS showing on slope?
49’
AD 1.1 : 6.1.1
What approach angle correlates to a PAPI four whites indication?
Greater than 3.5 degrees
AD 1.1 : 6.1.2
What length are runway centreline markings?
30 m long, followed by a 30 m gap.
AD 1.1 : 4.5.8
‘Distance to go’ signs may be installed on what runways?
- 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
What approach angle correlates to a PAPI four reds indication?
Less than 2.5 degrees
AD 1.1 : 6.1.2
How are ICAO ‘A’ touchdown zone markings implemented?
- 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
Where a sealed portion of the runway is not available for normal operations (e.g. a stopway), how is it identified?
By a series of yellow Vee bars marked along its entire length.
AD 1.1 : 4.5.7
How is a ‘Barette’ precision approach lighting system implemented?
- 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
What markings indicate a temporarily displaced threshold?
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
What eye height above the threshold would be expected on a T-VASIS showing 1 light fly up?
25 to 41’
AD 1.1 : 6.1.1
What approach angle correlates to a PAPI three whites indication?
Approximately 3.3 degrees
AD 1.1 : 6.1.2
What will you see in terms of runway lighting as you approach the end of the runway?
- 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
When are the ILS critical and sensitive areas protected?
- 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
