Just be careful about trying to put a factory built airplane on the register as "Experimental". What is it that you are experimenting with? Sure, sticking a diesel engine where a Lycoming once was is an experiment, as are modifications to the flying surfaces.

 

You are better off putting the airplane on as a regular registration, then if you seel it the new owner can keep it there, or stick it back on the RAA-Aus register without too much hassle.

It is not prohibited to change from RAA-Aus to VH registration. The major work is gathering all the paper work together. That means you will need all the engine and airframe log books and Maintenance Releases. Then you will need a weight and balance calculation, so you will need to have the data for Centre of Gravity as well as the location of the Datum points. You should be able to get these from the airplane's maintenance books, or manufacturer. Then you need to know if there have been any required maintenance notices (sorry forgot the right name for them)

 

The airplane will need to be inspected by a suitable experienced LAME. You will need to buy a new CASA approved maintenance log book. Then you will have to apply to CASA for a registration mark (VH letters). I suggest that you give Dave Dent at Dent Aviation, Camden a call (02 46551514). He's put heaps of airplanes on the Australian Register and knows the ins-and-outs of the process.

I agree with the idea of hitting the flying training as hard as you can, as often as you can. When I started to learn, I had saved enough money to buy a block of hours. I was at Uni and waited for a semester break and went and flew at least twice a day during the week, not weekends. I trained at Bankstown and it was busy back in the early 70s, so flying during the week got me less taxy/holding time and more air time (and I got a deal for paying up front - $17.50 per hour in a C-150). I still took a bit longer that I should have to solo, but that's because I'm ham-fisted.

 

I completed most of the syllabus, but then the money ran out and I was out of flying for a few years. I finally got interested again and had a job, so I saved up another wad of money, took my annual holidays and went flying. I completed my Restricted PPL and a few of my Navs before I had to go back to work and I saved more. After I had saved a bit more, I whacked it all down and completed my Navs in another block.

 

If I was renewing my licence (certificate) now, I think I would catch on a lot quicker because of the experience I've gained handling ground vehicles. When I was young, I didn't have the command confidence or the skills to be master of the airplane and make it do what I wanted it to. Now I have the confidence, and the theoretical knowledge to put an airplane where I want it to be.

The people beside 109 with the Rising Sun markings appear to be a Japanese ground crew with a European pilot and another European. Perhaps this is a pre-war photo of a Japanese evaluation test, and the Europeans are the demonstration pilot and a sales rep.

So OAE what you are trying to point out isn't the fact of a badgeries creek airport it is the fact that they are murmuring about getting rid of bankstown? Is that right or am I way off?

Quite correct. I've no complaint about Badgerys Creek. There is a need for expanded commercial aviation infrastructure in the Sydney Basin. I agree with Yenn that not all International travelers want Sydney to be their only destination, and it shouldn't be. However, the increasing size of the resident population needs another airport to allow the residents to fly to locations within Australia. Also, Badgerys is a good place to expand International and Domestic air freight as it is well positioned for linking air and ground transport.

 

What I wanted to point out is the crass stupidity and deception of politicians. The comments clearly show a desire for a land grab. Anybody with a smidgen of knowledge of the social and economic demographic of South West Sydney knows this comment, " It is easy to imagine Bankstown as the next Macquarie Park or Norwest Business Park, full of tens of thousands of high-wage jobs and providing employment opportunities for local people in Sydney's south and west." is pie in the sky. Tens of thousands of residents in South West Sydney don't have the education levels to gain high-wage jobs. Successive governments of both persuasions have pushed low income and blue collar types into that region (subject to the exceptions that prove the rule).

 

And who is to be the holder of the head lease at Badgerys Creek? If it is a mob like the Sydney Airports Corporation, then "In March 2010, the Australian Competition and Consumer Commission released a report sharply critical of price gouging at Sydney airport, ranking it fifth out of five airports. The report noted Sydney Airport recorded the highest average prices at $13.63 per passenger, compared to the lowest of $7.96 at Melbourne Airport, while the price of short-term parking had almost doubled in the 2008–09 financial year, from $28 to $50 for four hours. The report also accused the airport of abusing its monopoly power.

 

What chance would the small aircraft maintenance businesses currently barely keeping their heads above water at Bankstown have if forced over the Badgerys? And how would very light aircraft manage to get airways clearances to drop in at Badgerys for their 100 hourly's?

Another Cessna plummets from the sky and people on the ground are saved by the skill of the pilot.

The trouble is, is that Sydney really needs another airport and Badgerys Creek is the best location for it.

 

Why does Sydney need another airport. I don't believe that all the people who fly in to Sydney, actually want to stay there. The tourists wantto see other arts of Australia and it is just a pain in the butt for Queenslanders, Victorians and South Australians to have to travel via Sydney.A lot of the traffic could go to places like Rockhampton, Mackay, Cairns for example in Qld.

I don't know how Sydney compares with places like Heathrow, but whenever I have been there there seems to be plenty of time between traffic.

 

I can remember in the 50's Heathrow had 3 minutes between planes and I doubt Sydney is anywhere near that.

Thanks, you two for posting anything related to the original topic. I thought that I was starting a thread in which to discuss an aviation operations topic, but once again a thread has been sidetracked by pessimistic nit-pickers. If that type of people can think of nothing else but disaster scenarios involving light aircraft, then bugger off to a mass media Facebook page and spend time writing about Cessnas plummeting from the sky.

 

Now, has anyone got anything constructive to say in relation to the topic?

I'm throwing up my arms in despair at the deviousness of our politicians who try to deceive the masses with misinterpretation of reality. It seems that politicians have their eyes set on the land occupied by Bankstown Airport according to this report: http://www.australianflying.com.au/news/bankstown-airport-problematic-foley

 

In a speech to parliament , Foley,the State Opposition Leader, said that the rise of Western Sydney Airport would create air traffic issues and that the future of Bankstown needed to be considered. He used the air traffic issue to make a grab for the land by playing the "Jobs Creation" card.

 

"Our global economic corridor cannot be limited to Sydney's north and east. We must stretch the global arc to Sydney's south and west. It is easy to imagine Bankstown as the next Macquarie Park or Norwest Business Park, full of tens of thousands of high-wage jobs and providing employment opportunities for local people in Sydney's south and west."

 

"Planning and consultation around developing it as an employment centre needs to be initiated now. Part of this process will involve resolving where Bankstown's air traffic will go. Some of it, of course, can be relocated to the new airport."

 

Yes. The opening of Badgerys Creek will require changes to GA air movements in the Sydney Basin, but nothing serious enough to cause the closure of Bankstown Airport. How many GA airports are there in the vicinity of Los Angeles Inernational, and many other major airports? And if GA movements impinge on Commercial movments, how come we can fly a Victor 1 under K-S flight paths any day of the week?

 

"Foley's remarks come only weeks after the holding company that owns the leases for both Bankstown and Camden, BAC Holdco, was put up for sale." The fly in the ointment is that one of the conditions of the leases is that the leaseholder maintain the land for predominantly aviation purposes. The landlord is the Federal Government, so I don't see a major land sale in the future.

 

BAC Holdco is allegedly trying to get rid of its tenancy because the bean counters who originally saw holding the leases as a financial milch cow, soon learned that maintaining essential infrastructure can never be a profitable exercise.

Aircraft Spruce and Specialty have them: http://www.aircraftspruce.com/menus/cs/placards_aircraft.html

 

If you order from them, insist that they pack it in an envelope sized padded bag (if that's all you are buying at the time), otherwise it will come in a huge box and you'll pay a motza for the postage. If you tell them to send it US Postal Service Global Priority, you'll get it in a week. I suggest that you place your order by phone, or, if you have a headset and mike connected to you computer, use their online chat link.

Got to give some thought to the method of calculation, but I'm flat out like a lizard drinkin' at the moment. I'll get back to the problem tonight. I might even do Pommy Phil's trick of lubricating the grey cells with some Cab Sav.

 

OME

 

 

Yeah. I just used that figure for ease of calculation. Quoted figure is 16 - 19 lph.

 

When I get some moments, I am going to look at the Lift and Drag equations to see if we can calculate the relationship, Thrust = Total Drag.

 

According to Newton, once we get the airplane in straight and level flight at constant speed, then we only need to have Thrust equal to Drag to maintain the situation.

 

OME

 

 

Yep. That's the one. Thanks.

 

I was interested in comparing the electric motor with a 4 cylinder petrol engine.

 

Taking the Jabiru J170-D with a 2200 engine:

 

Engine Weight (complete to fit, without exhaust system) = 62 kg

 

Full fuel 135 l = 97 kg

 

Useful load at full fuel = 260 kg - 97 kg = 163 kg

 

135 l @ 20 l/hr = 6.75 hrs

 

Electric motor:

 

Motor weight (motor + controller circuitry + 21 LiPo batteries): 38 kg

 

135 l fuel weight in batteries = 75 batteries

 

Useful load: 260 kg + (62 - 38) = 260 + 24 = 284 kg

 

Total number of batteries equivalent to full fuel and engine = 21 + 75 = 96

 

21 batteries = 1 hour's power, 96 batteries = 4.5 hrs.

 

The big question to answer is: "How many units of horsepower are required to maintain straight and level flight at a constant speed?" In other words, if L = W, how much Thrust is needed to balance Total Drag?

Unless of course the Camden Control Zone is active, in which case to fly the RA-AUS aircraft you'd need a RPL or PPL with Medical (class 2 or AvMed).

I was just making the point that the medical standard required to fly identical airplanes are vastly different depending on the how the airplane is registered. I just used Camden as an example because I know that one of the flying schools has a foot on each camp. You are correct in mentioning the effect of the Control Zone being active. However, a person can undergo training on the 24- registration airplane under the cover of the CASA approved flying school which is also RAA-Aus approved, and during that training be flying around the circuit in the company of other students who are learning to fly in VH- registered airplanes going along the CASA path. Where's the logic for requiring medical clearance there?

 

OME

 

 

This is great news for owners of Jabiru powered planes

And then the fight started

 

OME

 

 

It looks like the way they have fitted the motor and battery to the airframe takes care of the balance problem, but then there is still the trade off for the weight of the unit. Too bad the article did not say how much the system weighed.

 

I think the engine in the plane is a Lycoming. Can anyone name the plane?

It seems that aviation regulatory bodies are being convinced that if car drivers can use a country's roadways with a simple medical clearance from the doctor who regularly cares for their health, then they are medically fit to operate an airplane in uncluttered skies.

 

Mind you, the doctors won't end up on street corners with a begging bowl. I had a medical to obtain a heavy vehicle driver's licence and it cost me around $180, and that medical was similar to the one for a Class 3 pilot's licence. It seems that it is only RAA-Aus certificate holders who don't need to fork out for a medical.

 

The stupidity is that I can go to a flying school at Camden and jump into a Jabiru 160 with RAA registration and fly it without a medical, but if I want to fly its sister shop which has VH- registration, I have to do a jig before an approved aviation medicine doctor.

I think that they are getting at something that seems to operate in the USA where the airfield is privately owned and there is a company whose business is on the airport. They call them Fixed Base Operators (FBO). The idea is that if you want to land at the airport you call up the FBO on a specific frequency (Unicom ??) and someone on the ground answers and is able to give you current information that you can use to make a safe arrival.

 

It is a bit like making an "All Stations ..." call at an uncontrolled airfield - like Narromine - and having Kev from "Kev's Propwash Shop" reply to tell you that there is a Drifter doing circuits on 06, the wind is 8 kts at 080, air temperature is 27C and QFE {local barometric pressure on the ground} is 1016.

 

Obviuosly, if CASA's ancestors in the 1930's had taken the approach to bolstering aviation that the FAA did at the same time, we would have a bustling general aviation sector servicing this wide brown land, and this whizzo new idea would be Ops Normal.

kcommxx,

 

If you examine things critically, you will soon come to the conclusion that in Australia, the most time efficient ground transport is the car. If you are flying at Bankstown, you have to get a train to Bankstown Station, then either a bus or taxi to the airport. Using public transport prevents you from being in control of the timing of your movements. So, I suggest that you use public transport to get to and from work, but use a car to get around at other times.

 

You will definitely need to put in a lot of time developing your driving skills if you want to drive in Sydney traffic. You've got two months' experience in Sydney traffic. I've got over 45 years' experience, plus I've been through advanced driving courses. I find that I am making more use of the skills I have gained through experience in recent years than I did 10 years ago. That's how much more hectic it has become in Sydney.

 

In comparison, flying around Sydney is like a stroll in the woods.
