Aerodromes State And Runways Flashcards
(28 cards)
What is included in the ARC
(Aerodrome Reference Code)
Aeroplane reference field length
Wing span
Outer main gear span
What is the ARC shown as
A number (field length)
A letter (Wingspan)
What is an ACN
(Aircraft Classification Number)
A number expressing the relative effect of an aircraft on a pavement due to:
Tire pressure
Footprint size
Max weight
No of wheels
When is an ACN issued
If an aircraft is 5700kg or more
I
What is a PCN
(Pavement Classification Number)
A number expression the bearing strength of a pavement for unrestricted ops
What is the relationship between ACN and PCN
If ACN is smaller than or equal to PCN = good to go
If bigger then will cause damage
If an aircraft is less than 5700kg what needs to be reported
Max weight and max tyre pressure
What is the ARP
Aerodrome Reference Point
The chosen geometric centre of the Aerodrome and the highest point on the runway
What does it mean by damp conditions
The water hasn’t made it reflective just a change in colour
What does it mean by wet condition
It’s reflective so soaked not standing water
What does it mean by standing water
3mm deep water on surface
What does it mean by contaminated
More than 25% of surface is covered by 3mm or more water
What are the 4 states of water on the runway
Snow
Frost
Slush
Ice
Where is the condition of the runway reported for water conditions
Snowtam which is only valid for 8hrs
A runway has 5 parts which are what
Taxiway
Thresholds
Clearway
Stopway
Strip
What is a hot-spot
A designated area which is known for potential runway incursions
How far apart are the touchdown markers
150m
Where is the threshold on a runway
At the start or end of the strip
What is the TORA
Length of runway available
Inc threshold
What is ASDA
Length of takeoff run plus stopway
What is TODA
Length of takeoff available plus clearway
What is LDA
Length of runway without stopway,clearway or threshold
What is a stopway
Has the ability to bear the weight of the aircraft and be as wide as the run way and be there if abandoned takeoff or stopping is needed.
