We think of the Antarctic as beingone of the coldest places on Earth,and indeed it is, with winter temperatures falling below – 60°Celsius. But it is summer and, inthe daytime, it rarely drops below – 20° Celsius.
Landing at night when the temper-atures are lower means that the icerunway will have a better surfacecoefficient of friction.

BLUE-ICE RUNWAY OPERATIONS - AIRBUS ACJ TO ANTARCTICA
Skytraders looked at a range of air-craft ranging from small to largebefore choosing the Airbus ACJ forits Antarctic operations. ‘We want-ed an aircraft without a point-of-no-return for the mission,” saysStudd, and the Airbus ACJ’s verylong range and modest size andweight make it great for the job.’
It operates the flights to and fromthe Antarctic on behalf of theAustralian Antarctic Division, andthe big benefit it brings is a reduc-tion in the time it takes to get sci-entists and their equipment to andfrom the region. ‘Under the bestconditions, it takes about ten daysto go by ship from Hobart to thebase at Casey, but it can take threeor four weeks if you get stuck inthe ice,’ points out Studd. ‘TheAirbus ACJ also costs less a day torun than a ship, says Studd, ‘andfreeing one up is helpful for marineresearch.’ The rapid flight time isalso of direct benefit to some sci-entists. He cites the example of oneresearcher that makes measure-ments of an isotope buried in 1,000metre long ice cores that are drilledout of the ice. The isotope breaksdown in about 24 hours so, untilthe flights began, it was not possi-ble to get them back to the labora-
tory in time for meaningful re-search. Some of the ice in thesecores dates from a million yearsago, making it a very special andunique insight into the Earth’s past.Other Antarctic research coversmany other fields – such as atmos-pheric measurements, geology,glaciology and work involvingplants and animals.

Garry Studd says: ‘The landingand stopping are not a problem –braking action is only slightlyworse than landing on a wet run-way - our biggest challenge is lat-eral control and handling the air-craft on the ground, especially instrong winds, when there is risk ofthe whole aircraft trying to ‘weath-ercock’ (point its nose into wind)’.He continues – ‘The team on theground measures the friction coef-ficient every 500 metres along therunway before we land and reportsto us by radio – if it is okay weland, and if not we turn around.’ Inpractice, the Airbus ACJ pilots arelooking for a runway friction coef-ficient of around 0.20 or better,before they will commit to a land-ing.
‘Blue-ice’ simply means a runwaysurface that is kept clear of snowby the wind and, at Wilkins, a 30knots wind is typically what youget. Meteorological measurements,made before the runway was built,allowed its centreline to be alignedwith this wind.‘The challenge comes when youtry to turn the aircraft around at the end of the landing roll,’ con-tinues Studd, ‘so we deliberatelyrestrict the Airbus ACJ’s centre-of-gravity when landing on ice to
keep a better distribution of weight on all three landing gear tooptimize the bearing strength ofthe ice and also assist us to make a 180 degree turn on the blue-icerunway in winds of up to about 50 knots.’
Skytraders operates its Airbus ACJwith four additional centre tanks(ACTs) in its cargo-hold – there isroom for a maximum of six – andappreciates the aircraft’s outward-opening cargo doors, which maxi-mizes the remaining cargo space.The extra fuel carried in thesetanks allows Skytraders to fly itsAirbus ACJ to Antarctica and backwithout refuelling, which bringsseveral important benefits. ‘First, itmeans that if the weather is notgood enough for a landing, we canalways turn around and fly back toAustralia, which is pretty impor-tant when you recognize that thereis no nearby alternate,’ commentsStudd. ‘Secondly, the Antarctic isvery much a pristine, unspoiledplace – one of the reasons it is sovaluable to scientists – so avoidingrefuelling means that there is norisk of contamination from a fuelspill. And thirdly, transporting fuelto the Wilkins runway would makeit very costly – perhaps as much as$25 a gallon.’

certificated aerodrome in Austra-lian territory. Situated 70 kilome-tres inland, and at a height of 2,500feet, the Wilkins runway is 4,000metres long and 100 metres wide.It comprises levelled blue-ice, andhas to meet the same stringentstandards required of other Aus-tralian airports – including nobumps above a certain height andother conditions. Crea-ting andmaintaining a surface of compact-ed snow, which offers better brak-ing action, is a constant challenge,and the surface can easily be des-troyed by a blizzard. Fortuna-tely,the blue-ice runway underneathcan still be used for landings, albeitwith some limitations.
Skytraders made its first AirbusACJ landing in the Antarctic on19th November 2007, at the USbase in McMurdo Sound, wherethe facilities are much larger andlonger established. This was fol-lowed by a first landing at Wilkinson 9th December, and full opera-tions were certificated by Austra-lia’s Civil Aviation Safety Autho-rity (CASA) in January 2008. ‘Wevery much appreciated the supportfrom Airbus for these pioneeringflights, especially that of Airbuspilot John Quinnell, who has beenthe life and soul of our operation inthe Antarctic, and that of retiredVice President Flight DivisionPierre Baud, who was with us onour very first landing at WilkinsRunway,’ says Studd.
One of the big challenges of regu-lar Antarctic flights is, of course,the risk of an aircraft becoming un-serviceable on the ground. Sky-traders works actively to minimizethe risk, by keeping the aircraftwell maintained and only commit-ting to landings when everything isin good working order. Like othercorporate jet operators around theworld, it also flies with an engineeron board. The Auxiliary PowerUnit (APU) is started at top-of-descent, for example, to ensure thatthere are at least two sources of airfor an engine start on the ground(the APU and the ground power
unit). ‘We also tend to avoidchanges to the aircraft configura-tion until we are sure that we canland’, says Studd.
But what happens if the worst hap-pens, and the aircraft becomesunserviceable on the ground? ‘Itmight take time, but we would finda way to fix it,’ says Studd. ‘TheAntarctic is a very special place,and people help each other,’ headds. ‘We tend to go only when theweather is good’, says Studd, ‘andin the Antarctic the weather is usu-ally either very, very good, or very,very bad.’
‘In practical terms, we are lookingfor a cloud base of 2,000 feet ormore, and a visibility of at least 10 kilometres, before we will com-mit to a landing’, he adds. ‘In wea-ther terms, one of the biggest dan-gers is the lack of surface defini-tion in the landscape, making ithard to judge how far away thingsare, and how high you are abovethem’, points out Studd. ‘This isexacerbated by a phenomenonknown as whiteout, which canoccur even when there is a highcloud-base and, sometimes, unlim-ited visibility.’
An established Global PositioningSystem (GPS) approach is usedwhen flying into Wilkins, and all ofthe bearings are ‘true’ rather thanmagnetic.‘We operate in ‘true’ or grid-basednavigation below a latitude of 60°south’, says Studd, ‘and making thetransition is very easy in the AirbusACJ – everything goes to ‘true’ onthe push of a button’. PrecisionApproach Path Indicators (PAPI)provide the final guidance in thefinal phases.
‘We will only land if there is lessthan 5 knots of cross-wind, we have‘primary’ GPS navigation and if therunway friction coefficient is 0.2 orbetter’, explains Studd. ‘We fly afully managed ap-proach and willtypically use medium autobrake forthe landing’, adds Studd.

square kilometres - more than
the whole of Canada and the United
States put together, and about
twice the size of Australia.
Paradoxically, for a land that has
so much of the world’s freshwater
locked up in its ice cap, Antarctica
is a very dry place. Parts of the ice cap
are more than 14,000 feet high,
and even the South Pole is some
9,250 feet high. Nobody owns Antarctica
although several countries, including
Australia, have territorial claims.
Some 45 countries are signatories
to the Antarctic Treaty, which currently
ensures the future of Antarctica
for scientific, non-commercial
and peaceful purposes.
Australia has the largest claim
to Antarctica – just over 40 per cent –
and runs three scientific research
bases, at Casey, Mawson and Davis.
Turboprop CASA 212s - equipped
with skis – and operated by Skytraders
are also used for flights within
Antarctica on behalf of the Australian
Antarctic Division.
�‘Airbus ACJ Family’Airbus has created corporate
jet versions of its aircraft from time
to time since its early days, but
it was not until 1997 that it entered
the market in a more comprehensive
way, with the launch of an A319
derivative called the Airbus Corporate
Jetliner (ACJ).
Featuring a VIP or other cabin chosen
by the customer, extra fuel-tanks
in the cargo-hold for intercontinental
range, high-thrust engines for good
takeoff performance, built-in airstairs
and a richer specification,
it has established itself as the new
top-of-the-line in corporate jets,
delivering more comfort and space
than traditional business jets.
The Airbus ACJ Family, which now
comprises the A318 Elite, ACJ
and A320 Prestige, has won more
than 100 sales, worth more than
$5.5 billion since its inception,
and continues to win new business
from private clients, companies
and governments.
It is complemented by VIP widebodies
ranging from the A330/A340 through
the A350 and all the way up
to the A380, for customers
that want even more comfort
and space, as well as the range
to fly ‘non-stop to the world’.

Paradoxically, for a land that has
so much of the world’s freshwater
locked up in its ice cap, Antarctica
is a very dry place. Parts of the ice cap
are more than 14,000 feet high,
and even the South Pole is some
9,250 feet high. Nobody owns Antarctica
although several countries, including
Australia, have territorial claims.
Some 45 countries are signatories
to the Antarctic Treaty, which currently
ensures the future of Antarctica
for scientific, non-commercial
and peaceful purposes.
Australia has the largest claim
to Antarctica – just over 40 per cent –
and runs three scientific research
bases, at Casey, Mawson and Davis.
Turboprop CASA 212s - equipped
with skis – and operated by Skytraders
are also used for flights within
Antarctica on behalf of the Australian
Antarctic Division.
�‘Airbus ACJ Family’Airbus has created corporate
jet versions of its aircraft from time
to time since its early days, but
it was not until 1997 that it entered
the market in a more comprehensive
way, with the launch of an A319
derivative called the Airbus Corporate
Jetliner (ACJ).
Featuring a VIP or other cabin chosen
by the customer, extra fuel-tanks
in the cargo-hold for intercontinental
range, high-thrust engines for good
takeoff performance, built-in airstairs
and a richer specification,
it has established itself as the new
top-of-the-line in corporate jets,
delivering more comfort and space
than traditional business jets.
The Airbus ACJ Family, which now
comprises the A318 Elite, ACJ
and A320 Prestige, has won more
than 100 sales, worth more than
$5.5 billion since its inception,
and continues to win new business
from private clients, companies
and governments.
It is complemented by VIP widebodies
ranging from the A330/A340 through
the A350 and all the way up
to the A380, for customers
that want even more comfort
and space, as well as the range
to fly ‘non-stop to the world’.
BLUE-ICE RUNWAY OPERATIONS - AIRBUS ACJ TO ANTARCTICA
Antarctica, once the preserve of polar explorers, is now regularlyaccessible to scientists through regularflights by the Airbus ACJ, helping usto understand more about our planet.Conscious of the need to preserve this pristine wilderness for generations to come, the flights are made in an environmentally responsible way,
with careful preparation and operationhelping to ensure safety in challengingsurroundings.The Airbus ACJ’s ability to handle a wide range of climatic conditions meansthat it takes these demanding operationsin its stride, highlighting once againthe versatility and operational flexibility of the modern Airbus family.
