Chapter 5.3 - Aerodromes and ALAs Flashcards
What does ALA stand for?
Aircraft Landing Areas.
Name four factors that determine whether or not the Runway can be used?
- Runway Weight Limit.
- Runway Type Pressure Limit.
- Runway Width.
- Operational Restrictions.
Name four Runway factors which are needed to check the Aircraft’s performance?
- Runway Surface.
- Runway Slope.
- Takeoff and Landing Distance Available.
- Elevation.
Certified/Registered Aerodromes: What are the ranges in length for a Runway?
400 to 4000 metres.
Certified/Registered Aerodromes: What are the ranges in width for a Runway?
18 to 45 metres.
What does RESA stand for?
Runway End Safety Area.
What does ASDA stand for?
Accelerate-Stop Distance Available.
What’s the main difference between a Clearway and Stopway on a Runway Strip?
Stopway will usually be prepared to carry the weight of an Aircraft.
Define Obstacle-clear Takeoff Gradient?
The slope of the surface from the end of the Runway Strip to the highest obstacle in the Takeoff Climb.
What does TORA stand for?
Takeoff Run Available.
What does TODA stand for?
Takeoff Distance Available.
What does LDA stand for?
Landing Distance Available.
Except in an Emergency, what is required to use an ALA?
Consent from the owner/occupier.
Define ALA Clearway?
An area with no obstacles with a slope of 2.5% from the end of the Runway over a width of 45 metres.
Define Fly-over Area?
The ground adjacent to the Runway Strip with no obstacles.
Define Lateral Transitional Area?
An area extending outwards from the outer edge of the Fly-over Area on either side of the Runway.
ALA: Minimum length of a Runway?
15 metres.
ALA: Length of Runway Strips?
30 to 45 metres wide.
ALA: What’s the maximum percentage for the Longitudinal Surface Slope?
Should not exceed 2%.
ALA: What’s the maximum percentage for the Transverse Surface Slope between Runway and Runway Strip?
Should not exceed 2.5%.
ALA: What’s the maximum percentage of the Transverse Surface Slope between outer edges of Runway Strip to Fly-over Areas?
Should not exceed 12.5%.
Which colour markers are used for an ALA Runway?
White.
Name four types of Runway markers used for an ALA Runway?
- Cone Marker.
- Inverted Bucket.
- Road Safety Cones.
- Flush Marker.
Which colour markers are used for an ALA Runway Strip (2)?
- White for Runway Markers.
- Yellow for Apron and Taxiway edges.
Name two types of markers for an ALA Runway Strip?
- Cone Marker.
- Gable Marker.
Other than markers, what other main requirement is required for ALA?
Wind Direction Indicator.
Name two types of surfaces at an ALA which can degrade the performance and landing of an Aircraft?
- Rough.
- Soft.
How can an ALA be tested for rough surface?
By driving a vehicle at a speed of 75 kilometres per hour.
How can an ALA be tested for soft surface?
By driving a vehicle in a zigzag no less than 15 kilometres per hour.
