Flight 1: Cessna 172 VH-BUA

Flight Log | Posted by Dan Cowell

Flight 1 – VH-BUA (Bravo Uniform Alpha)

Signed in and got a visitor’s pass first, then did the pre-flight brief.  Learned about climbing, cruising and descending and then went out to the aircraft (a Cessna 172) for an introduction to the flight controls.

Found out about fuel straining and what to look for in the preflight walk-around and got taken through the checklist.

I got to taxi the plane down to the end of the runway.  I was all over the place.  I could hear the whole airport laughing at me in my imagination.  :p  The rudder pedals are harder to get the hang of than I thought they would be.  Andrew (my instructor and all-around great guy) told me that I was doing better than most trainee pilots do in their first lesson – apparently most of them almost go off the side of the taxiway!  He said that if others did as well as I did, there would be a lot more good pilots in the world… Though I think he might have been exaggerating a little.

He managed all of the communications with the tower, and we stopped at the holding area at the end of the taxiway before being given runway clearance and finally, clearance to take off.

We climbed to our assigned altitude of 1,500ft and after reaching it, Andrew gave me control.  We headed southeast, following the coast to Byron Bay.  Along the way I did my first climb, up to about 2,500ft.  To climb, you push the throttle all the way in and pull back on the control wheel.  Coordinating that was hard enough, but it was easy compared to adjusting the trim while maintaining the climb.  As you get the trim right, the resistance on the control wheel drops, and if you’re not careful, you will end up pulling up too much and climbing too fast.

The initial plan was to perform another climb to 3,500ft but there was a cloud ceiling at about 3,000ft that put an end to that idea.  We stayed at 2,500ft for most of the flight.

Being out of the controlled airspace around the airport, we were allowed pretty much free reign, as all northbound aircraft are directed around the training area.  When we reached Byron Bay, I did a large left hand turn out over the water and around the headland.  It’s a different feeling flying over the water.  Not -bad- per say, just different.  The lack of landmarks can be disorienting and you might as well be in the middle of the ocean for all you can tell your position.  I imagine it would be easier if there was less cloud cover and if there were watercraft to provide some idea of position.

After doing a few turns and a couple of laps around Byron, we turned northwards on a 0 degree heading.  We followed the coast over land up toward Fingal Head, and Andrew pulled out the throttle, which caused us to start descending.  We descended to 1,500ft according to instructions from ATC.  I had to pull back on the control wheel to prevent us from descending too fast.  About a mile from Fingal we were directed over water and we passed between Cook Island and Fingal Head, at which point Andrew took control.

ATC directed us to continue long into the wind overwater as we travelled past the airport.  Andrew explained that this was so the controller could safely direct other aircraft overland, away from us.  I think it was more for the other aircraft’s safety than ours.  ;)

ATC estimated another mile before they could clear us to turn for final approach.  It was about this time that Andrew started a slow descent (much slower than mine) to 1,000 ft.

We came around and followed another Cessna 172 in to land.  He seemed rather slow in clearing the runway – or at least slow enough for Andrew to make comment.

As we came in to land, Andrew pulled the throttle right out, taking the engine almost to idle.  There was a bit of a crosswind at (if I remember correctly) 220 degrees.  I’m glad I wasn’t landing.

With landing finished, Andrew switched the radio frequency to Ground Control who cleared us to the taxiway.  We cleared the runway quickly and took the nearest taxiway to Air Gold Coast’s hangar back to the tie-down point.  Ground Control instructed us to hasten our taxi as another aircraft was awaiting taxi clearance.  I couldn’t see the aircraft myself.

That concluded the flight – Andrew took care of the shutdown checklist, and we vacated the aircraft.

Skills Learnt:
Cruising
Climbing
Descending
Banking/Turning
Taxiing

Issues:
Taxiing needs a LOT of work
Seemed to be climbing slightly while cruising – trim?
Coordinating trim adjustment during climb & descent
Too much focus on altimeter at this stage
Seat could possibly be a bit more forward

Cost: $285
Total so far: $285

Aeroplane: Cessna 172
Flight time: 1.1 hours
Total so far: 1.1 hours

Distributed Solar & the Problems with Photovoltaic Power Stations

Uncategorized | Posted by Dan Cowell
May 19 2010

The vast area requirements of the generators is the biggest problem with photovoltaic (solar) power systems. Hundreds of hectares of solar cells can only provide enough power for about 15,000 homes; an energy density easily surpassed by all other forms of electricity generators. Following closely behind is the issue of storage. The sun only shines on a given area of the earth for part of the day, excluding of course the extreme north and south of the world, where “days” lasting up to 6 months are followed by 6 months of darkness.

The solution, which is rapidly gaining support in the commercial market, is distributed solar power. These systems typically take one of two forms. Grid-connected photovoltaic arrays mounted on rooftops or on specially-constructed frames on private land, or self-contained units that are installed in devices with a rechargeable battery to power solely that device (typically lights.)

The need for storage, as well as the the issues with density call for careful consideration if solar power is ever to become a primary means of electricity generation. I believe the answer is to bring the two concepts of grid-connected arrays and self-contained units together, to create a true distributed solar power solution.

The current thinking with grid-connected systems is that the power required for the grid-connected home is first taken from the photovoltaic array mounted on the property. The surplus power is then pumped back into the grid. I propose taking a similar approach with self-contained appliances in public space. Imagine, if you will, a city where each street light is powered by a battery housed in the light itself. The light turns on at dusk and off at dawn, while the battery is charged throughout the day via solar power. When the battery is fully charged, a switch is triggered which causes the power generated by the light’s solar panel to be offloaded onto the grid.

Voltage drop would not be an issue, as the power would be offloaded onto the local grid. The only issues that may arise would be regulation of power output, however a similar system to the current grid-connected systems could be put in place.

The system as described here is only a supplemental measure, and obviously the light example is just that, an example that can be expanded to any public area, from awnings over public toilet blocks to sheds with roofs covered in photovoltaic cells, all of which are connected to the grid. Imagine a city where every house has a roof covered in solar cells, all supplying power to the grid where needed, with most public utilities supplying supplemental power as well. Without long-distance transmission lines, and a grid dependent on only a few points of supply, there would be a much more stable infrastructure, where a break in any number of lines, including the complete isolation of a suburb, would not cause an outage, but merely a slight drop in overall power supply for the affected area. When the sun sets, of course, they’ll be out of luck, but at least the street lights will be on! Distributed solar could account for up to 50% (in an ideal world) of our energy needs over the course of a year. The only barriers to it now are cost and infrastructure adaption, which hopefully will come sooner, rather than later.

The Lost Art of Analytical Reading

Uncategorized | Posted by Dan Cowell
May 13 2010

These days we have at our fingertips the greatest single repository of human knowledge since the great library of Alexandria in ancient Egypt.  Community websites like Wikipedia and various commercial ventures provide floods of information in detailed, lengthy articles, with every possible piece of data imaginable presented to the user at face value.

This torrent of information comes at a cost.  With articles on certain topics running for pages on end, brevity and skillful writing are sacrificed in order to present information it its plainest, most easily accessible form.  Statistics litter the pages, and convenient hyperlinks allow for explanations of certain terms to be spoon-fed to the reader in even simpler discourse.  The consequence of this is that when people are confronted with an artice written in concise form, which relies on context to be interpeted and that, when interpreted correctly contains much valuable information, they are at a loss.

Stargate Iris Framed & More

Uncategorized | Posted by Dan Cowell

This will probably only interest a very few people, but hey!  That’s what this blog is for!  For me to broadcast my opinion to the world and to get a false sense of inflated self-worth by believing someone cares!  :D

Today I got my Stargate Iris piece that I bought at Supanova back from the framers.  They did a great job.  :)   Here’s a photo:

Anyway, after getting it home, I decided to hang it on the wall with my photo of the Southern Cross and the Pointers that I got a number of years ago at Parkes Observatory.

DSCF5573-F800x600

Next on the list of things to buy:  Replicator blocks!

After hanging my new shiny, I was overcome by a desire to tidy up.  So I spent the next three hours turning an absolute pile of chaos into this:

If you’d seen what it was like before, you wouldn’t believe it was the same room.

Supanova 2010 – Day 2

As usual, pictures at the end.  :)

The first thing that anyone going to Supanova thinks of is the line.  The line on the Saturday is indescribably long, and if you want to walk from one end to the other, you’ll want a packed lunch and more than one bottle of water.  In fact, if you can get your hands on a camel, you’re probably almost ready to make the trek.  Every year, there is at least one person who does it right, and I am incredibly envious of their foresight and planning.  See exhibit A:

How to wait in line.

Unfortunately, the number of people that organised is low.  See exhibit B:

Supanova 2010 – Day 1

If you just want to check out the gallery of photos I took, go straight to the end, otherwise, read on! :)

I was late to the opening day of the Supanova Pop Culture Expo in Brisbane this year, however that pales into insignificance when you consider how close I was to not going altogether!  It was only on the Friday morning that the money I needed to buy my tickets came in, and even then I only had about $200 to spend the entire weekend.  Either way, I got my tickets, did a solid day’s work and then went up as soon as I could.

Due to the size of the expo last year, they kicked off proceedings at 1PM instead of 6, and due to work, I was unable to make it up there until about 5:30.  The good thing about this was being able to miss the queue for picking up my tickets.  The bad thing was that the main hall was almost empty, with most people going over to the preview night.

The Fantastic Bar Staff

As I’m sure many people know, today the Mana Bar was officially opened to the public. People started lining up at 9AM, and by the time 12 noon rolled around, which was the time I rocked up, the line was already about 75 people long. There was one common feeling: Anticipation. At the head of the line were Mario, Waluigi, Wario, Princess Peach and Princess Daisy, while the Little Sister patrolled up and down the line, looking sinister. More pictures and the full review after the jump!
