Annex 14 - Aerodromes Flashcards
What are Aerodrome Reference Codes
Number followed by a letter
What is the Aircraft Classification Number (ACN)?
An Aircraft with a MCTOM of more than 5,700 kg is issued with a ACN
The ACN is a number expressing the effect of an aircraft on a pavement with a specified standard sub-grade category.
What is the Pavement Classification Number?
PCN is a number expressing the bearing strength of a pavement for unrestricted operations.
An aircraft with a given ACN may operate on a surface with a lower PCN if certain limitations are met:
* Rigid Pavment 5%
* Flexible Payment 10%
What is the Aerodrome Reference Point?
- An ARP shall be located near the Initial or planned Geometric centre of the Aerodrome and shall normally remain where is was first established.
- The ARP is the coordinates of the Airfield.
What is a damp runway surface?
- Damp: Surface has a change of colour due to moisture but is Not Reflective.
What is a wet runway surface?
- Wet: Surface is soaked and Reflective but there is no standing water.
What is standing water?
- Standing Water: Water that is more than 3 mm deep.
What is a contaminated Runway?
- Contaminated Runway: Runway where more than 25% of the surface is covered by ‘Standing Water’.
What are the four defined states of frozen water on a runway?
- Snow
- Frost
- Slush
- Ice
What is slush?
Slush: is water saturated snow which with a heel and toe slap down motion against the ground will be displaced by splatter.
What is the braking action table for snow and ice?
How long is a SNOWTAM valid for?
8 hours
What does a temporary and permanent threshold look like?
What colour are displaced threshold runway edge lights?
Red
What are hot spots?
are areas designated as having the potential of causing a Runway Incursion. Extra vigilance is required in these areas by the flight crew.
What does a stopway and clearway look like?
How is a stopway defined?
How is a clearway defined?
What are the declared distances? Define, TORA, ASDA, TODA, LDA
What is a primary runway?
Primary runway means an existing or planned paved runway, on which a majority of the approaches to and departures from the airport occur.
What is the Rule of thumb for runway width?
Number of stripes x 4 = Runway Width in Meters
What are runway threshold marking dimensions?
What is the runway strip?
What is a taxiway strip?
What is a graded area on a runway?
That portion of a strip of an instrument runway That is intended to serve in the event of an aeroplane running off the runway.
What is the runway end safety area?
Aircraft stand markings should be provided to designated parking positions on?
Paved Aprons.
De-icing Anti-icing Facilities.
Aprons must identify the shoulders of the apron and the non-load bearing
areas by a….?
pair of solid yellow lines.
What are fillets and what are there purpose?
- Taxiways may need to be widened around corners by the introduction of fillets.
- Fillets are meant to provide clearance between the outer main wheels and the edge of the taxiway.
- The strength of fillets should be the same as the taxiway.
High Speed Taxiway Integrated/Rapid Exit Taxiway Integrated lights are what colour? What is the distance between the lights?
Solid Yellow Lights, 100m
What are the alternating green/yellow/green/yellow lights beginning with green?
Lead off or Lead in lights.
What are stopbars?
