“Whilst CASA has continued to review its operations and streamline them wherever possible the shortfall in the funding of the aviation regulatory services has continued to increase and is expected to continue to do so under the current arrangements,” http://australianaviation.com.au/2015/04/industry-calls-for-rethink-of-new-casa-charges/ It's a good read

The batteries are sucking up some of the spikes too

To get free right seat time at least offer to clean the plane. Hanging around an airport a lot will help Flight time clarification - no you can't log hours as PIC outside the training area (25nm, direct track etc) unless the flight is approved by and operated under the supervision of a flight instructor http://www.comlaw.gov.au/Details/F2013L00218 See division 61.A.3

Flew under an overcast just high enough to let me do what I needed. 1.6 hours including my first PIC flight for the year. Wind was mostly down the runway

If he'd told you why the paper plane flew as part of the class, maybe not so much. Mine was a train buff so the maths was about friction, slopes, acceleration due to gravity and other two dimensional Newtonian-ness

The one I can hire, isn't broken and isn't at the back of the hangar. That would be my favorite

Ops manual section 2.15-6 clause 19 (a) suggests the AIP is reference material. Section 3.01-3 clause 6(d)(x) says "and your flight training facility should have copies" It doesn't specifically reference either AIP for last light (nor should it) Bob Tait BAK 2008 edition Air Law (section 10) also says refer to AIP GEN and AIP ENR. Page 10.22 question 20 regards last light. Aviation Theory Centre BAK 2008 Air Law chapter 5 references AIP ENR s1.2 but doesn't have a question on last light. Next edition probably will, now. Don't have a Dyson Holland book handy. The question comes up a fair bit. Don't get too bummed about not getting an exam question right because it is not in your study guide. The CASA VFR pilots guide is free in electronic form and is searchable. A student should at least have this as a copy and it rarely gets updated. Part 61 changed a few things but not too much. Half the fun is reading the WHOLE section to see what else you missed or didn't understand. Mine was carriage of animals (CAR256a) and guns (CAR143). Ironically they appeared next to each other in the VFRG. Go figure.

VFR Guide page 110 references AIP Gen 2.7 s1.1 for the definition of last light AIP ENR 1.2 s1.1.2 contains last light rule for Day VFR. Tell me which book you are looking at and I'll try to find it for you. Your book will most likely reference both of these. From AIP Gen 2.7 Last Light is defined as "End of Civil Twilight" however if you are on the South Eastern side of a hill and a bit down a valley, last light can happen a lot sooner

Depends on how the map graphic was created

One example of a 4 to 6 tonne helicopter uses 400 Kg or 490 litres of jet fuel per hour. A Boeing 747 on full fuel averages out at one litre per second per engine door to door. In comparison a Bell jet ranger will use 80-90 Kg per hour or a quarter of the fuel to produce one fifth the power.

It's all about the Reynolds number. A turbine the size of your thumb feels air molecules like they are ball bearings. The Rolls RB-211 has a compression ratio of 27:1 at sea level but the colder less dense air at cruise allows a compression ratio around 39:1. Depending on the altitude the engine can produce 25 to 30 MW Newer turbines will go as high as 50:1 but the flight level atmosphere is 1:100 as dense as at sea level. The pumping losses on a small turbine are huge because of the effect of the Reynolds number on high speed air travelling through relatively smaller cross sections. Refer this link, page 18 for a deeper understanding The History of North American Small Gas Turbine Aircraft Engines http://books.google.ca/books?id=V0SnFt8JGokC&pg=PR3&source=gbs_selected_pages&cad=2#v=onepage&q&f=false For reference 1 sea level atmosphere is 14.69 pounds per square inch (PSI) or 1 Bar. Petrol engines top out reliably around 55 PSI boost for short bursts, diesels can go a little more. The maximum overall compression ratio would be (let's say 60 PSI boost) 4 Bar x 18:1 or 72:1 less the pumping losses. I'm not going into how or why this is bad for smog production but it really is. A piston warbird will see 60 inches MAP or +1 bar of boost on top of approximately an 8:1 compression ratio but at the expense of TBO. The Solar T-62 is a centrifugal turbine found in the early Chinook helicopter that produces around 80-95 HP for 65Kg but it has a woeful 5:1 compression ratio and only runs at one speed. Often a turbine isn't the best choice for an application, rather it's the only choice. Everything else will still use pistons.

So a question was asked and the person asking already knew the answer. There is only only RA-Aus school registered at Goulburn although memory says there are two. Well, good luck with that. I'm not playing. In future please reference a public announcement from the organisation concerned, CASA, RA-Aus or some primary source that has authority to make definitive statements and a charter to do so. May I suggest this drift continues on PPRune, where it belongs?

No idea. Do share?

It's not $200 for the Cessna. YSCB charges $12.50 per arrival for CAC aircraft inclusive of TNC. Goulburn also charges even for the aircraft owned by the AOC holder, but not $12.50 http://canberra-aeroclub.com.au/cac/index.php/aircraft-menu/club-aircraft

And there is an ILS at Oakey

International standard atmosphere ir 29.92 inches of mercury. When the engine is turned off the manifold pressure will read about this or a bit less if your field elevation is a bit higher. 28 inches is 948 HPa which you will get around 1000-1500 feet AMSL. So if the engine is stopped and you are standing at 1500 feet above the sea on a nice day with the grass airfield begging to be used ... Etc etc ... 28 inches it shall read. This is the theoretical limit for the engine at wide open throttle (WOT) too, in the absence of forced air flow and pumping losses. The higher altitude you go, the lower the WOT value will be. Anyone with a constant speed propellor feature endorsement goes through this learning. The EJ25 will shift 2.5L of air every two crank revolutions. So at 6000RPM (just a number for the ease of math) with no pumping losses the engine will pass 7500 Litres of air a minute, mix it with liquid fuel and poop out a bit more because now it's got combustion products mixed in with it. At sea level that would be 7.5 Kg of air. At 948 HPa or 28 inches of mercury it's 7.0 ish kilograms per minute or 420 Kg per hour. Now we look at kilograms of air plus kilograms of petrol. Conventional wisdom says the ratio of air in kilograms to petrol is 14.7 : 1 if it's pure octane e.g. Like 100 Low Lead. Let's say the engine runs at 5300 rpm and 28 inches as suggested. That gives us 6.2 Kg of air per minute or 372 Kg/hr with an expectation that 25 Kg of 100 octane petrol would give the best mixture. In practice, it's a bit richer as the engine produces more power more safely at WOT if the mixture is rich. Lets go for 30Kg per hour. Convert 0.72 Kg of petrol to one litre and you get 34 litres for 25 Kg and 41.6 litres for 30 Kg. The engine is doing fine but probably could be richer at WOT if it is often operated at sea level on hot days. The extra fuel will help to keep the head temperatures down. 22 litres per hour is 63% of the WOT value therefore the same percentage of the WOT power

Ask the cows

They all look like they are upside down. They look the same to me. Please, not another episode of "guess what this was before it got totalled"
