Call me weird but I have difficulty viewing helicopters as flying machines, let alone something that levitates using gas. It will fail & be relegated to being an advertising billboard.

The downside of a slow flow (nipple a crack) is that you don't get the potential benefit of scouring and the job will take a lot longer.

Yeh! but if so desired, they could take all the ocean to climb .

The whole thing is a joke - in the first instance, you can't be prevented from landing and taxiing to the tie-down area (hopefully well away from any RPT activity). Nor can you be challenged while sitting in the aircraft - its only when you sally forth, that matters have the potential to become officiouse. I think it was the last time, BC, I went on a trip & landed on a ADSCA (to meet a friend/passenger) - taxied away from RPT area (no aircraft waiting) towards tie- down, spied an active maintenance hangar nearby - parked as close as safe/reasonable and walked over to the hanger . Had a nice chat with the LAIMS therein. RPT landed. Exited the public access to hanger, walked up to airline building, found friend. Had a drink/munch returned with friend via maintenance hangers - departed. No stress, no challenge - all good.

Interesting - in particular the observations regarding Australia's massive cultural cringe (my condensing words) , which still seem to raise its ugly head today.

If you have the time, may be worth waiting for the E - my Airmaster is approaching + 12 kg on the nose

FYI - Check the weight of the Airmaster CS and then compare with the EProp CS

Cats are amazing - such soft cuddly looking creatures but look what armament they are hiding - good thing we don't have the larger members of the feline family in Australia.

Oh that one! Have browsed it several times - can't see a reference to private pilots wishing to land/short or long stay at a AD Security Controlled Airport - in the main, it seems to refer to employees of one sort or another. Perhaps private pilots dont need an ASIC - here's hoping. I would invite Markdun to cast his legal eye over https://www.auscheck.gov.au/security-card/aviation/asic#:~:text=An ASIC is evidence that,the airport owner or operator. and give his interpruitaton/understanding (without prejudice).

Don't start me on the road rules - another collection of evidence lacking BS. This whole paragraph would seem to be about international ports of entry/exit . "drug smugglers, quarantine evaders" are almost exclusively in the International realm - not dometic RPT. Your "range of "bad actors"" need only purchase a ticket to gain entry to an RPT aircraft and will be aided to board by all the ASIC wearing staff. Far from perfect????? - As it relates to, almost all, domestic RPT airports, its a complete and utter failure of intent & execution. This has been tried by many with little or no response/action - the only remaining avenue, is to vent on Forums like this.

Sorry Turbs - cant remember/find your posting . Please repost or give detailed instruction as to location.

RF - After much experience/experimentation, I have found that pressurising the system, to bleed & stop, prevents any air from entering (the nipple once cracked/open is not an airtight valve) AND in addition may have a scouring (cleaning out) effect due to the sudden rush of exiting fluid. No offence but your idea, while good in theory, does not accomodate any imperfections (air/fluid leaks) in the system. The imperfections may be due to nipple manufacturing tolerances, dirt, wear or seal deterioration. The problem with nipple integrity, can also cause the vacuum bleeding system to be ineffective. As to returning fluid to the reservoir - never having had spontaniouse air in a functioning brake system, I am always bleeding to replace old fluid or air bleed after a brake repair. In either case I would not return potentially contaminated fluid to the reservoir. What is the significance of "the Piper has 5 cylinders... (park, 4 pedals) "?

Thanks for taking the time Mark to demonstrate that justice is not about fair play or reasonable action - in the end about who has the power.

Out of interest; If the above be the case, why then is QANTAS being taken to court over phantom ticket sales? The, want to be, traveler (applicant), has payed for & received a ticket, the company does work to this end and will honour the agreement sometime (just not for the service expected). Its possibly not the best example but in both cases the vendor (QANTAS & Federal Gov) is providing a doubtful service It seems to me a "contract" can not be valid, if the applicant (pilot) is essentially coerced into instigaton, no matter the work (checks) that is then triggered in a third party. Coerced in the sense that the pilot is being pressured (fines for non compliance) to apply & pay for a service he/she does not want or believe will be delivered. For a contract to be valid the pilot must have the expectation of receiving a material benefit (increased individual & public security). It would seem that there is no significant increase in individual or public security, around RPT aircraft, at most domestic airports, therefor the contract has not been discharged. It would also seem that the Federal Gov (the contractor) has no intention of improving security (no personnel, no follow up) in this situation, again the contract has not been discharged. It should not be forgotten we are talking about access to a public airport/facility. Any on going barrier to this access would need to have very strong justification. No such justification has ever been presented .

I assume you have an assistant "depressing brake". I have trained mine to loudly intone DOOOOOOOOWN (slow depression)- UP. I find a ring spanner to be the best for working the nipple. The bleed hose goes on after "cracking" the nipple, while spanner remains in place. OPEN bleed niple slightly after the down commences. CLOSE nipply just befor end of down. Repeat, until no sign of old fluid or air. I usually start with the slave/wheel cylinder closest to the reservoir - carefully drain as much old fluid as you can, avoiding sucking air, before adding fresh fluid to the top of reservoir. Your assistant is in charge of replenishing reservoir as needed. In a vehicle - avoid depressing brake pedal all the way to floor (if in doubt small wooden block placed under peddle) prevents possible overextension/damage to piston rubbers. Opening nipple slightly after assistant commences down stroke, ensures a good high pressure scouring (removal of any contaminants including air) of system. Closing nipple, while under pressure, reduces chance of air entry, as does Blues partially filled baby food glass jar (I use a peanut butter plastic one). In an aircraft I use both bottom up, and bleed down (very similar to vehicle technique). I have tried vacuum bleeding with some success. Sometimes removing air bubbles just requires a sufficiently fast flow of fluid, to force the air to exit with the fluid - do whatever it takes.

Only done the brakes on three aircraft (several times) - despite two being the same "model" the brakes were slightly diffrent, requiring a flexible approach to bleeding. I think that's part of the problem, no two systems are exactly the same. I doubt the type of hydraulic fluid makes much difference to "bleeding". I don't think there is much if any functional benefit in using aviation fluid V automotive, other than cost & ease of acquisition of automotive. NOTE: Check and double check you are using a fluid compatible with your system - the wrong fluid is likely to damage seals/buckets and leave you with no brakes and much expense. I do think the systems, on RAA class aircraft, can be difficult due to using very small ID pipes, lowish pressures/flow (particularly for hand actuated systems), odd pipe routing (sometimes a U bend or a master cylinder, traps air, makes life difficult), duel masters, small capacity reservoir or no reservoir, etc etc In my limited experience, a combination of techniques (including much bad language)seems to deliver a non aerated fluid. Once you get to that happy place, every effort should be made to avoid future air entry.

Maaaate! The trick is not to get air in the system in the first place.

Never had what I would call problem Nev (I do my brake fluid every 2 years or KM's, whichever comes first). With the aid of a well trained family member, on the brake pedal and topping up the reservoir , ( I do the sometimes messy/dirty job underneath) it all seems to work out very well. it would seem most if not all cars of the 2000's have ABS - so far no probs.

Come come - should a disgruntled person wish to hijack an RPT aircraft, they just need to purchase a ticket and be ushered onto said aircraft by all the ASIC holding staff.:)

Just had a random thought: Does not our law require that payment for a service/good can not be demanded (illegal) where no such service/good exists (eg QANTAS is facing court over selling tickets for non existent/cancelled services). I would suggest that ASIC is a non service (in that it provides no demonstrable benefit to the customer - we the proletariat ) and therefore illegal under our system of law.

Thanks for confirming my long held opinion of ASIC. As I understood ASIC applies to almost all RPT airports, and all areas within the so called secure areas (I hear derisive laughter). Access, by non ASIC holders, will not be available for at least 1/2 a day, every time an RPT is due. Two RPT's, a few hours apart ,will see the airfield closed. The fining of non compliant pilots - The reality is that the authorities are, in lieu of adequate policing/implementation, using the threat of a large fine to frighten pilots into having an ASIC. Do we have a police state? There is no good reason for ASIC to be imposed on the vast majority of inland RPT airports - it's the proverbial crock of.... Bad legislation: Australians have a long and glorious history of ignoring bad legislation (even when the authorities refuse to remove it from the statute books). Unfortunatly this leaves the legislation available, when the authorities decide to makan example of someone - throwing the book at the poor sod.

For the purposes of section 31 of the Act, the following type of airside security zone is prescribed, that is, the security restricted area.

Good system BUT again don't get hung up on just one way of doing it. Aeroplanes are not like automotive systems (easy as) they are finitiky buggers that may need more than one technique to get to that airless happy place😁

I use disposable syringes (purchase from chemist or animal feed merchants) & clear hose to suit (Bunnings) - low cost & can, with care (flush with metho or Iso, lube plunger with silicon) be reused several times. The amount of brake fluid is very small, so a 100 mm (or smaller) syringe will usually do the job. Don't get hung up on bleeding from the bottom - you may find that you bleed from wherever, to get that last bit of air out of the system. If possible never drain your brake system ie when replacing fluid, use fresh unused fluid to flush the system, avoiding air entry.

I assume you speak in jest
