More info on June 3rd Class D changes

A week into the new Class D rules at former GAAP airports, here are some useful bits of information I gleaned around the web. I haven't flown under the new rules yet, but that should be fixed very soon, more on that further below.

CASA released an updated version of the Sydney Basin Visual Pilot Guide. The 78-page document contains detailed information for safely navigating the airspace around Sydney under the VFR. This includes flying in and out of Bankstown and Camden which are now Class D aerodromes, the Victor 1 and Harbour Scenic procedures as well as tips on avoiding violations of controlled airspace.

The June edition of From the Tower, the newsletter from the kind ATC folks at Bankstown Tower, has a map of the manoeuvring area at Bankstown that I mentioned in the previous blog post, which can also be found on the official website of the airport. The newsletter also contains very useful examples of typical radio calls at Bankstown on the ground and in the air under the new Class D rules. And, as icing on the cake, they used Schoies airplanes and parking areas as examples!

A few changes to the Bankstown procedures as published in ERSA on June 3rd are available through NOTAMs. Pilots now need to report on downwind, and establish contact with ground after landing and clearing all runways, not just monitor ground as stated in ERSA. If you need to know more, you certainly know where to find NOTAMs too.

I flew a short dual flight last week to regain recency in the Arrow. We went to Camden via Mayfield, did a few circuits and came back even before the morning surface inversion disappeared: we could still see smoke plumes from local factories rise a little and then go flat.

Apart from that over the last few weeks I have been preparing for an exciting flying trip over the coming Queen's Birthday week-end: from Sydney to Brisbane and back in Arrow VH-SFJ, together with two other Schoies pilots. With a bit of luck we may even make it to Fraser Island for some very scenic flying.

We had a planning session in a meeting room where I work that was really successful. The 450NM journey from Sydney to Brisbane fits within four VTC charts, which when put end to end almost cover the entire length of this table.


Ed had brought in his laptop with Command Flight Planner, an awesome Australian flight planning software. With the flight planner on the video projector and all the maps on the table, this normally boring corporate meeting room took the allure of a RAAF briefing room. Or so we liked to believe.


Pizzas and Coke were brought in to sustain the intense cerebral activity. The plan so far is on day one to fly coastal from Sydney to Archerfield, the GAAP Class D aerodrome of Brisbane, with a stop in Coffs Harbour, fly to Fraser Island and back to Brisbane on day two, this time overnighting at Redcliffe aerodrome, and hopefully fly back to Sydney inland on day three.

That's the plan, and of course things won't go completely according to plan, which is always half the fun as long as you have a backup plan or two. Whatever happens you'll read about it either here or in the newspapers. :-)

Changes to Australian airspace on June 3rd

On June 3rd, a number of changes to Australian airspace classification as well as operations at non-towered aerodromes will come into effect. Whatever one may think of the changes themselves, the communication campaign run by CASA was quite impressive and, I like to believe, effective.

I read the briefing package sent to me by CASA, I attended the workshop at Bankstown and I used the online training package. I even listened to Peter Gibson, corporate communication manager at CASA, explain the changes on the always excellent Plane Crazy Down Under podcast. And I noticed the big flashing sign at the main entrance of Bankstown airport on my way to the pilot shop.


So, what are these changes about? In short, GAAP aerodromes will become Class D aerodromes, but not the Class D as we know it, a new kind of Class D that's modelled on the FAA Class D, not the ICAO Class D. This despite the fact that one of the stated goals of the changes was stronger ICAO compliance. Go figure. And airports already in Class D will of course switch to the new Class D.

So we'll end up with three types of aerodromes instead of the current four: Class C where separation is provided by ATC through radar identification, Class D where separation is provided by ATC in a purely procedural manner, and non-towered aerodromes in Class G where pilots provide their own separation using the good old see and avoid principle.

Except that see and avoid becomes alerted see and avoid since the carriage and use of a radio at all certified, registered and military aerodromes becomes compulsory on June 3rd.

In former GAAP aerodromes, taxi clearances will now be required, but only for taxiing in the so-called maneuvering area, which contains the taxiways in direct proximity to the runways and the run-up bays. No need for a clearance to move an aircraft from one end of the apron to the other for refuelling for example.

Going from GAAP to the new Class D, VMC criteria for vertical cloud clearance are increased from clear of cloud to at least 500ft below clouds and 1000ft above. This may have major consequences for circuit operations since it is not uncommon to have good visibility with ceilings below 1500ft. Will ATC instruct pilots to fly circuits at 800ft if the cloud base is at 1300ft? Or not issue clearances for circuits at all and only allow VFR pilots to arrive or leave the control zone under Special VFR? The CASA and Airservices Australia representatives at the workshop made it clear that they will be monitoring the impact of the changes closely and may issue amendments or fine-tune local procedures at certain aerodromes using NOTAMs.


The main changes at non-towered aerodromes concern circuit entry and altitude. We are now allowed, although this is not recommended, to join the circuit on base. The larger changes are about circuit altitudes: GA aircraft remain at 1000ft AGL, but ultralight with a cruise speed under 55 knots need to fly 500ft circuits, while faster airplanes, with cruise speeds above 150kt , typically turboprops such as the SAAB 340, will be flying 1500ft circuits.


I'm curious to see how this will work out in practice. I mean, whichever altitude they fly a circuit at, all aircraft need to get down to ground level eventually. Will we be safer with different types of aircraft at different speeds and different altitudes, but with the added risk of descending or climbing through someone else's circuit altitude? At least with everybody at the same altitude faster aircraft could safely overtake slower ones.

One side-effect of this rule is that overfly altitude will mechanically move from 1500ft AGL up to 2000ft AGL if turboprops may be around. Spotting the windsock suddenly became a lot harder. There is an interesting bit of information found in the CAAP 166-1(0) which states that aerodromes with runways lengths below 1400m are unlikely to receive turboprop traffic, hence overfly can take place as in the past at 1500ft.

I realise I haven't been blogging too much recently, mostly because I didn't do too much flying, and the flying I did, although extremely enjoyable, was not terribly blogworthy. But that's all going to change soon with a planned endorsement to fly the glass cockpit DA40 that the club just put online, and a very exciting trip to Brisbane in Piper Arrow VH-SFJ planned for Queen's Birthday week-end with a few other Schofields Flying Club pilots.

Which will give us plenty of opportunities to try out the new Class D procedures at Bankstown, Coffs Harbour, Archerfield and Sunshine Coast. And hopefully also visit a few non-towered aerodromes on the way. More blogging to come, more photos and hopefully a few new videos thanks a set of camera mounts I offered myself as a birthday gift. Stay tuned!

Spot the airfield: Casino

Birds do it. Bees do it. Even pilots with over 10,000 hours do it! Let's play spot the airfield again. This time on a flight from Sydney to Brisbane in a Qantas Boeing 767-300. Our track took us right over the town of Casino in Northern NSW, just south of the Queensland border.


The horseshoe-shaped lake on the right-hand side of the airport is called Horseshoe Lagoon. Casino being about 30 nautical miles from the ocean, I reckon calling this pond a lagoon is a stretch of the imagination. Global warming may prove them right eventually though.

The main runway is 10/28, with a strip for gliders right next to it. I mean, not a parallel grass runway, the glider strip is adjacent to the runway and form part of the same runway surface, the limit of which is marked by just one set of gable markers.

Casino is named after its sister city of Cassino in Italy. No significant gambling activities there, which didn't prevent a facetious person at Airservices Australia from assigning the name GAMBL to a nearby IFR waypoint.

The airfield being uncertified it does not receive any RPT traffic, the locals go to nearby Lismore to catch up a Rex flight to Sydney.

The Casino region is a big cattle farming area. With the Casino Beef Week only a few weeks away, this is as good a reason as any other for a cross-country flight. For a very tasty $100+ burger, straight from the producer!

Aviation in New Caledonia

Nina and I spent ten days in New Caledonia over Easter. While the trip was not aviation-themed, one cannot avoid airports and airplanes when travelling from a very big island to a smaller island and eventually to an even smaller one.

We flew from Sydney to Nouméa in an Aircalin Airbus A320 codeshared with Qantas. While Air Calédonie flies domestic routes, Aircalin connects New Caledonia to international destination such as Australia, New Zealand, Tahiti, South Korea and Japan. The Airbus A330 below was about to leave Nouméa Tontouta airport for Tokyo Narita as flight SB800.


This 300,000-inhabitant island in the Pacific has two airlines, and the capital Nouméa has two airport: Nouméa Magenta right near the city for domestic flights and General Aviation, and Nouméa Tontouta far from the city for international flights.


We spent a few days driving around the main island, taking in the sights, feasting on fresh seafood, deer meat and untreated tropical fruits and arguing politics with a few strongly-opinionated Caldoches.

For the last part of our trip we entered an Air Calédonie ATR-72 for a 20-minute flight to the Isle of Pines. New Caledonia being a French overseas territory, airplanes are F-registered, such as the two ATR-72 F-OIPN and F-OIPS below and the one ATR-42 F-OIPI above. The ATR-72 is the stretch and re-engineered version of the ATR-42, in the same way the Qantas fleet has both old Dash-8 and new Q400 aircraft.

The last two letters of the tail number refer to the three districts that make up New Caledonia: Province du Nord, Province du Sud and Province des Iles Loyauté.


All three twin turboprops were on the tarmac at Magenta airport that morning, boarding and unboarding a mix of tourists and locals.


The tail art uses traditional Kanak elements. In the middle of the circle is a flèche faîtière, a totem-like pole structure found on the apex of most traditional dwellings in New Caledonia, as can be seen on the traditional hut represented on the left of the rudder.


Magenta airport has a local flying club called Aéro Club Calédonien, with the usual fleet of Cessnas and Pipers but also a Mooney M-20J and a couple of TB-10 Tobago. Not bad at all when you consider that there are only 15 airfields in New Caledonia. Fiji is a bit far, but I wonder how often single-engine airplanes attempt the 100-nautical mile crossing to nearby Vanuatu.


We flew back in a Qantas 767. Tontouta airport has a long runway but no parallel taxiway, which forced our airliner to backtrack the whole length of the runway so that we could depart to the south-east on runway 11.


The airport is surrounded by hills and mountains, so finding an elevated point to build the control tower wasn't too hard:


Tontouta is a joint civilian-military airport, with units of both the French Navy and Air Force stationed at the Base Aéronavale de Tontouta. No jet fighters though, only helicopters and transport turboprops. That's their hangars on the photo below.


The thing that I found absolutely astonishing aviation-wise is that a small airport such as Ile des Pins (NWWE) has a control tower and rescue vehicles on standy at the airport even though it never sees more than four commercial flights a day. By way of comparison, Wagga Wagga airport in Australia sees about 10,000 RPT movements a year and had its tower closed down in 1996.

The stark contrast between these two approaches to the provision of air traffic services stems from the two very different business models Airservices Australia and the French DGAC operate under. Airservices Australia is a government-owned corporation that charges fees, makes profits and even sometimes pays dividends back to the Commonwealth. The French DGAC is a government department and as such is more concerned with spending money than making money. There are pros and cons to each approach obviously.

On a more touristy note, New Caledonia is a gorgeous location with a fantastic mix of landscapes and cultures. It is also poor value for the region and the infrastructures for tourism are not as developed as one may wish. If you're looking for a resort-style holiday on a Pacific island, go to Vanuatu or Fiji.

If, on the other hand, you speak French and want to discover a fascinating place fast approaching a turning point in its short history, New Caledonia is for you. The country is still struggling with de-colonisation and reconciliation and will have to decide in a few years wether to become fully independent or remain a French overseas territory. From our very short stay, we could see that opinions on that last point are very much split.

Spot the airfield: Armidale

On a Qantas flight from Brisbane to Sydney aboard a Boeing 737-800, the cloud cover turned from broken to few soon after we crossed the state border, which allowed me to spot Armidale airport. That's all part of the game of spot the airfield which I like to play from the back of the airliner.


The town centre is to the right of the shadow cast by the cumulus cloud, while the aerodrome is to the top-left of the photo, near the New England Highway .


Armidale airport (YARM) has a main 05/23 sealed runway with a comfortable length of 1738m, and a shorter 09/27 grassed gravel runway. The elevation is 3556ft, which is very high by Australian standards and is easily explained by the location of Armidale on a plateau in the middle of the Great Dividing Range. I guess local student pilots learn very early on the importance of computing take-off and landing distances.


After Armidale "our" airliner tracked in the direction of Scone, passing over lake Glenbawn and the Hunter River.


Just a minute later, an open-sky mine (of the type sung by Midnight Oil before its lead singer chose an alternative career path) could be seen south of Muswellbrook. That's still the Hunter River in the background


And for a slightly more challenging game of spot the airfield, what about photographing Boeing's factory from the International Space Station?

Paragliding Sydney's Northern Beaches

Aeronautical information published by Airservices Australia goes through four amendment cycles every year: information contained in the AIP book, DAP and ERSA is updated with each amendment cycle, while charts are only updated every other amendment cycle.

This is why VFR pilots need to buy a new VTC (Visual Terminal Chart) every six months. The other reason is the constant folding, unfolding, marking tracks, erasing tracks and using the Tasman Sea area for writing clearances and the ATIS. There's only so much abuse a chart can take. I just added two bits of tape to my current VTC and it has to last me till June. And I didn't fly that much. Charts seem to be designed for self-destruction when no longer current.


Now, what happens when a chart needs urgent updating that cannot wait for the next amendment cycle? That's when NOTAMS come in, such as this one found in the FIR section of the NOTAMs for Area 21:

AMEND HANG GLIDER SYMBOLS ON AIP SYDNEY VTC AS FLW:
ADD JOINING RED LINE BTN THE SYMBOLS AT NEWPORT (S33 40.0 E151 20.0)
AND NARRABEEN TO INDICATE THAT HANG GLIDER OPS OCCUR AT OTHER POINTS
BETWEEN.
FROM 12 142123 TO PERM

Clearly, if pilots expect hand gliders only at these two points while they can in fact be found anywhere in-between, this is a safety issue. So I took my nicest red pen and joined the two points with a nice, thick and conspicuous red line.


After patting myself on the back for having read the NOTAMs in full and spotted this one, I was left wondering where those hand gliders on the Northern Beaches would launch from. The roof of the Bahá'í Temple? The top of the lighthouse at Barrenjoey Head? Or are we talking about parasailing? It's all relatively flat out there, and I couldn't remember seeing nice cliffs such as those found near Stanwell Park.

Thanks again to the Almighty Internet, I discovered the Northern Beaches Hand Glider Club. They launch both hand gliders and paragliders from a number of locations along the aforementioned red line: Newport, Mona Vale, Cooks Terrace, Warriewood, Turimetta, and all the way south to Long Reef.

Most of the launch sites have an elevation of about 100 feet. My guess is that they use a combination of thermals and ridge soaring to stay up in the air, otherwise that's a very short glide down to the beach. Pretty impressive. A pity they do not offer joyflights or instruction, those sites are much closer to my house than Bankstown airport.

Wilkins Runway, Antarctica

If you had to choose between Iceland, Greenland and Australia as the country which built a runway out of compacted snow and ice on top of a glacier you would be forgiven for discarding Australia straight away. And you'd be wrong.

I found the ad below in the aviation section of The Australian a while back, which reminded me of the existence of the Wilkins Runway, a 3500 meter-long (that's 11,500 feet) runway built a few years ago in Antarctica.

The scientists and support staff working at the various scientific bases over there can now enjoy the convenience of a weekly airline service, which beats having to spend two weeks on a boat crossing some of the roughest seas on the planet.


Skytraders operates this very peculiar airline with one Airbus A319 fitted with long-range tanks. The flight from Hobart, Tasmania to Wilkins Runway takes approximately 4.5 hours and takes place about once a week during the summer period.

Since meteorological conditions are rather unpredictable and unforgiving, and alternate airports are few and far between in that corner of the world, the airliner always has the option of flying all the way back to Hobart. That's quite smart, since it also eliminates the need for refuelling in Antarctica.

The runway is actually made of hard blue ice on top of which a layer of compacted snow was laid down. Snow provides better grip than ice and also does not melt as much under the sun. Still, the Airbus 319 Flight Policy issued by the Australian Antarctic Division says that at times during the summer, flights will be constrained by temperature and friction issues at Wilkins Runway. Flights during this period may only occur during “night” hours.

There is no entry in the ERSA for Wilkins Runway, but an RNAV approach can be found. The runway is called 09T/27T. The letter T refers to the fact that all headings are in degrees true, as opposed to degrees magnetic. That's what happens when you get too near a magnetic pole: magnetic declination is too large and unpredictable to predicate aerial navigation on compass readings. The aerodrome chart mentions the existence of a PAPI on 09T.

Another thing I didn't know is that the Australian Antarctic Territory is the largest chunk of Antarctica. Amazing what you can learn through an interest in aviation.
