Going to 'The Dish' (Parkes)

Flight hours: 3.3
Study hours: 0

Note: This event occurred during October

Preface: The plan was to fly out to Parkes and go visit the dish. The only preparation outside of flight planning was to ensure that the radio telescope was open for tours. Hilarity ensues.

Guest writer: Wade Beattie AKA Turtle

It was an ordinary day, besides waking up late next to a few empty bottles of Bacardi Rum. Today we were going to fly out to the dish, the same radio telescope that was used in the movie 'The Dish'.

Getting out to the airport, it was the first time I had seen a light aircraft up close. I was surprised at how cramped you could get inside a small plane when you pack a couple of motorised scooters. Also the fact that weight and balance can be an issue and that the windows opened... Cool.

Geoff's preparation of the navigation logs, fuel, charts and instruments seemed complex, but he assures me that anyone can learn. Before pulling the aircraft out of the hangar, I was shown how to perform the first daily inspection, a detailed check of the various aircraft systems and flight controls.

We taxied out to the run-up area and had discovered a rough running engine when only using one magneto. That was soon sorted out by leaning the engine and running a slightly higher rpm.

Before long we were airborne after a crosswind takeoff, which I found interesting as when we gained altitude, the plane was turned into the wind by a large degree, yet we were still flying straight ahead.

We flew west over the Blue Mountains and initially the bumpiness and hangover started to gain control. Soon after, the air smoothed out and everything was 'plane' sailing. Geoff never tired of me speaking as a captain or randomly yelling out "Contact!".

Approaching Parkes, we flew over the airfield and the windsock was swinging in different directions up to 180 degrees making it harder to pick the best runway. I was a little worried as when I asked the captain what we were going to do because of the changing wind, his reply was "Not sure, I think I need to use a lifeline and phone an instructor. Can you pass me the phone? We didn't cover landings in training".

After a smooth landing, we parked the plane and prepared the scooters. We were using the scooters to get ourselves around town. The airfield is about 6 kilometres from the town centre and we found out that the road to get there was a highway. Perhaps we should have booked a taxi!

Leaving the airfield on our scooters, stunt driver Geoff decided to navigate himself over a cattle grate at full speed. In the process, the scooter partially disintegrated when the rear wheel was forcefully ripped off the scooter after it was launched skyward from hitting the first grate.

The scooter came to a sliding stop, sparks being generated from the steel frame sliding along the bitumen, with Geoff perfectly balancing on it. The engine was still producing power and the rear wheel flicked up into the air, over Geoff's head and bounced down the road. To put this into perspective, Geoff is 6 foot 4.

He turned around to face me and cut the engine. Now we had to find the wheel and I had to manage to not crash my scooter by the fact that I couldn't stop laughing. On quickly inspecting the scooter, we found we could fix it if we could get some tools. Amazingly the chain had not broken.

Taking the scooter back to the airport, we found an aircraft mechanic and borrowed some tools so that we could start our repairs. This involved bending the frame straight, removing the rear brakes and re-inserting/re-tensioning the rear wheel.

One hour later we were back on the highway, but only after we lifted the scooters over the cattle grate. Travelling along the open highway at 40 kilometres an hour, we soon reach the town centre only to find that my scooter now needed a service, the clutch was no longer supplying power properly to the rear wheel.

After borrowing more tools and fixing my scooter as best we could, taking the better part of another hour, it was time to think about flying home. At least we know how to find Parkes and that scooters were impractical for this airport. Perhaps we should spend a night or leave earlier in the morning so that if we have to conduct ad-hoc repairs, we have enough time for a tour as well.

Flying back home, Geoff let me fly most of the way back. I had trouble with altitude and directional control initially, so that we were heading south instead of east, but this was fairly short lived and I felt relaxed at the controls.

Geoff performed a wing over near a Sydney's Warragamba dam. Wingovers are fun. Back at Bankstown, we cleaned the plane and put it away.

Still looking forward to seeing the dish.

Brisbane Scenic and the flight home

Flight hours: 5.2
Study hours: 0
Aviation Reading: None

Wade and I decided to take a leisurely scenic flight around Brisbane and the islands before I had to finalise my preparation to depart for Sydney.

There is a published VFR track that takes you south of the city, over to Stradbroke island, tracking north to Moreton island before crossing water to the west for Bribie island and finally now being north of the city, returning to Archerfield.

There were some interesting colours to be seen, the coast and islands looked great from the air. Pity about the low cloud which reduced picture clarity.



During some of the island hopping, I decided to provide Wade with a taste of what a zero G environment feels like. Seeing as I still had the sound recorder hooked up, I decided to record the experience. You can listen to it here (Warning: Contains Explicit Language).

On the return trip to Sydney, I decided to re-record most of the radio conversations again for my Student Pilot Training podcast listeners. This is because I totally screwed up major portions of the radio conversations on the first trip by failing to ensure that the unit was able to record at the correct volume and also because I needed better settings to transfer the recordings to my laptop.

The weather ahead looked like it wanted me to make a diversion back to Byron Bay, where my friends Bill and John were still staying. No drama, diversion adventures crop up occasionally when flying light aircraft.

The cloud cover was getting increasingly lower than forecast and I had to transit the Gold Coast Class C airspace at 1,500 ft, whilst dodging small areas of rain.

The cloud cover was lighter and higher when passing Byron Bay, which saw me climb to 6,500 ft. Visually ahead however, the clouds looked broken to overcast, below my current altitude, covered the entire horizon and extended one hundred miles or more.

I didn't want to find myself above an overcast and unable to descend when needed. Calling up Flightwatch, I was informed that Sydney has unlimited VFR. I decided to fly VFR on top, using the breaks in the cloud every few minutes to maintain visual tracking along with using navigational aids to backup my track made good.

Passing Coffs Habour, the clouds started to clear over the coast and I was able to maintain 6,500 ft for most of the trip home.

The Bankstown ATIS on my return had the wind at 05010G20KT. That means the wind was coming from 50 degrees, at 10 knots gusting to 20kt. The ATIS broadcast crosswind maximum was at 18kts, 3 knots higher than my Cessna 172's crosswind limitation.

The landing was quite interesting, having to adjust the aircraft at all stages of the circuit for landing. The flare, landing and roll out all required correct crosswind technique, otherwise it may have been an unhappy landing.

Flying between Sydney and Brisbane is quite fun in terms of the radio work, the number of differing airspace areas and the different weather patterns you may encounter. I would recommend it to any private pilot for flying, radio and decision making experience.

Byron Bay and BrisVegas

Flight hours: 3.7
Study hours: 0
Aviation Reading: Aiming High

A good friend of mine lives in Brisbane whilst another is taking a short holiday on the eastern most point of Australia, Byron Bay. What a perfect excuse to take a short break and fly myself up the coast to visit them and score some free accommodation.

The Sydney area had quite a lot of low cloud hanging about, however it was forecast as fine and sunny along the coast up to Brisbane. The clouds wouldn't present a problem as they were high enough for me to fly the Sydney lane of entry and soon after, I would be descending to 500ft to pass the Williamtown military area, which would then open up into better weather.

My trip today would take me to Tyagarah, a grass landing strip right on the water near Byron Bay. I planned to fly coastal most of the way, with only a detour around a restricted area used as airforce firing grounds if it was active.

During the flight, I recorded the radio conversations as an opportunity to present my podcast listeners with a wide range of radio calls including GAAP, CTAF, CTAF(R), Class C, Class D, Sarwatch and Restricted airspace. I will put the radio calls together and publish it in the next podcast.

The sky was BKN55 (read: Broken cloud at 5500 feet) and I didn't have enough light to take good photos, so hopefully the trip back will present better conditions for photo opportunities.


The weather was much better in Byron Bay and after meeting up with my friends, we hung out at the beach and went for a swim, followed by some relaxing drinks at the beach hotel.

The next day, I left the boys, prepped the plane and flew up to Archerfield, the GAAP airport in Brisbane. I have never been to Archerfield before, so it was important to read all of the relevant material and instructions in the airport directory (ERSA).

I will be staying in Brisbane for 3 days before flying back home, but my next flight may be a scenic around Brisbane and the coast.

The DJ's mums B'day

Flight hours: 1.0
Study hours: 0
Aviation Reading: Aiming High

I've been fortunate enough recently to be regularly judging or being a VIP of the local Inside Sport model search events. These events allow me to have unfettered access to the models and because I have been taking Trieu, my friendly Asian photographer, he has been snapping up literally hundreds of excellent semi-naked photos at each event both backstage and on.

But that isn't the point of this "aviation" blog. What point am I trying to make? Oh that's right.

The main host on some of the nights was none other than MJ, a Saturday night DJ from Nova 969 (radio station). It was his birthday the night we met and I was soon invited to the crazy party that was to ensue on the following Saturday.

During the party I met MJ's parents and soon after, MJ asked if I would be able to take his Gold Coast living parents out for a flight around Sydney for his mothers 50th birthday. No sweat.

A few days later, the trip was arranged and it was looking like a great day from the ground albeit with some smoke haze from recent bush fires. The visibility was forecast as 8 kilometres in haze and a high was over the Sydney basin area along with light winds. Fairly stable weather.

I arrived early to the hangar, pre-flighted and swept the hangar in preparation for my syndicate's annual general meeting the following night.

The sweeping was interrupted due to my required attendance on a global conference call. Soon after and about 2 hours after I actually arrived at the airfield, the whole tribe arrived being his parents and his two brothers. MJ knew I would only take two people on board my Cessna and everything was cool, the boys would wait near the car whilst we went flying.

Briefings were performed and we were soon in the air. Climbing straight into thicker than forecast haze. The go-no go decision was made harder by the fact you couldn't determine what the haze was doing from the ground.

The haze wasn't a problem below one thousand feet, with visibility ranging between 6 and 8 kilometres (confirmed by reference to what towns I can see and how far away we were according to GPS), but around 2500 hundred feet, visibility was significantly reduced. Still legally visual, but not the best weather for a scenic flight over the city.

I descended back to 1500 feet and on approaching the control zone, requested clearance to the harbour which was approved. Approaching the city, the haze was quite thick and would have made for terrible photos. I amended my clearance request and descended to 500 feet to fly along the Victor one coastal route.

It was much clearer at this level and if I didn't like the look of the haze at Wollongong, I would return north along Victor one before returning home. The horizon was becoming quite difficult to see, so as to require straight and level flight to be based on instruments.

The haze down south was much the same, so we continued the flight back home over the national park and around the Holsworthy military restricted zone by use of instruments for flight and navaids for pilotage.

On approaching the airfield, the ATIS was now reporting 3 kilometres visibility and restricted VFR. The winds had also picked up in the area, thickening the haze band and making it denser in the process.

I was told by ATC to hold at my inbound reporting point known as 2RN. I put the Hoxton Park frequency on my second radio unit to improve my situational awareness, as the departing traffic from Hoxton can come close to 2RN, my holding location.

I positioned myself further west of 2RN so as to not be right over the top of 2RN at the same altitude as other traffic that may be approaching the airfield via 2RN.

Just as I was completing an orbit, I had spotted another inbound aircraft (Cessna 172) that proceeded to fly over the top of 2RN and continue north-east bound. It had no strobe or navigational lights switched on.

I kept a close eye on the traffic and was soon cleared to join crosswind as number one in the circuit. I informed the tower of the unidentified aircraft approaching the GAAP control zone.

I noticed that the other traffic was turning left and right and changing altitude by up to 300 feet either side of the required inbound altitude over the next few minutes. Keeping an eye on the other traffic at all times, I joined crosswind and as I was starting my right turn to downwind, I noticed the other traffic was also turning downwind and was now at a much higher speed possibly from a descent. I decided to slow down and would inform the tower that I am going to manoeuvre behind this other aircraft and that it may have an electrical fault.

The radio soon sprang to life with the pilot in the other plane reporting inbound 2 miles north of 2RN. (In fact, they were around 4 miles north east, towards the airfield and on an extended downwind).

The tower mentioned the other traffic in the circuit (me), and the pilot mentioned he didn't have me in sight.

I was on the right hand side in relation to the other aircraft, at his 2 o'clock and no more than one mile away. He was also now at the correct altitude.

As we were effectively on a collision course, I radioed the tower to say that seeing as he didn't see me, I would further slow down and slot in behind him. I also mentioned to the pilot that his lights were not on. He acknowledged but no lights ever were switched on (I noticed this much later after seeing him land).

The poor visibility was easily confirmed by the fact that it was difficult to see the airfield when on downwind.

The other pilot flew the largest circuit I have ever seen, so wide that to maintain my usually very tight circuits, I had to slow down to roughly 60 knots to await his return from outback Australia and turn final on 29R.

Again this other pilot astonished me by ignoring the crosswind alert on final and allowing the wind to swing him through the runway centre airspace.

I didn't have a chance to go up and talk to this person after shutdown, but I wonder sometimes if these types of pilots ever learn that they made mistakes, could have made better decisions and that they were putting other peoples lives at risk.
