Looking at the E-Props GLOR-3-170-C8-T. Looked at going for a ground adjustable and still might - but I am not a 'fiddling' sort of person. Certainly will not be doing my own annual servicing etc. It's not about the maximum speed increase, it's about operating the engine in its maximum torque range with a lower throttle setting for range increase. I only have maybe 280 kgs to play with for useable load and 2 people my size and baggage etc eats considerably into fuel that can be carried. And yes, I know that the CS gear will weight, but the decrease in burn will more than compensate for that.

Hi. Looking for opinions on fitting a 2 blade or 3 blade propeller to my Rotax 912is with a constant speed unit. Just in the ordering phase and wonder which I should go with. The airplane will be primarily used for cruising and won't be operating out of marginal strips. I know that the old wisdom was that 3 blades were better for takeoff and 2 blades for cruise as the 3 blade was 1) heavier and 2) had more drag, but a lot of that was based on either fixed pitch or ground adjustable propellers and is the wisdom still valid for operation with a CSU (mechanical knob to a hydraulic actuator) in the age of the new composite materials (light & stiff) the blades are constructed from.

Greater than 80% load factor AND on routes around the 8 hours is their sweet spot. With lower passenger loads the 747-800 and 777's easily outdo it for fuel burn, and much greater then 8 hours the economics become less advantageous. Tis an exponential thing. For a European carrier such as Emirates that have a high density economy section and short leg lengths it works and works well, and it would be OK for Oz if we only flew to Asia....... It also works with high density and slot constraints, ie, the number of movements you are allowed at airports. But again, only with a very high passenger load as landing fees are based on airplane weight. With the same passenger load doing an LAX-SYD, the old 747-400 used some 30,000 kgs less fuel, and the Virgin 777's (when they were around) would do 30,000kgs less again than the 747. The A380 can't fly as far south (Latitude) between Aus and South Africa or South America than the 747's due ETOPS, so has to fly further and more fuel. Yes, they are a 4 engine airplane, but the outboard engines provide thrust only, same as the A340's. The right airplane for Oz was the 747-800 but Boeing got it going too late to get enough orders in to make it viable.

Once again Australian CEO's are cleverer than the rest of the World. A380 was a shockingly bad choice to begin with and only happened because Airbus gave away free A330's to go with the purchase deal.

I believe that RAAus is working on having the BFR done in an RAAus aircraft be valid for your CASA licence as well as your RAAus certificate sometime in the future. Possibly tied in with RAAus instructor ratings be accepted as CASA endorsements. Don't hold your breath .........

sometimes they find a target to home in on .... taken from my office window a few years back

Don't know where you are getting your LAME from, I have been quoted $2.5 to $3 thousand pa for an LSA with 912is with constant speed prop.

I think they have a choice .....

December 24, 2015 Arizona Senate President Andy Biggs on Tuesday appointed Sen. Sylvia Allen as the new chairwoman of the state's Senate Education Committee. And what better role for Allen, who has been building her credentials for years with bizarre statements on chemtrails and a fervent belief in creationism, than leader of an education-focused body? They are all just nuts over there ..........

Torque

Sorry - you think that EV's (cars/scooters/motorcycles/airplanes) use lead acid batteries? Lifpo battery for 2 hours lighter than your 98 octane (11.2 kgs by the way) and an electric motor lighter than your 40hp conventional engine. Your argument doesn't carry weight .....

Like this a lot. All it needs is an electric drive and you can sit in it as well ...........or add a folding electric scooter to your away kit for an additional 30kgs and you can tow it. Handy to get into town or that camping spot on the beach.

Rotax 912 requires oil change at 50 hour intervals on Avgas - 100 hour intervals on Mogas. The issue, besides lead fouling everything, is cost...........

Flew an airplane I had flown many times previously from new for 1st flight after repair (fairly major) and it flew way better than out of the factory. Tolerances, rigging etc new are "as long as it is in tolerance it's OK" whereas the repair put everything smack in the middle of where it should be.

Like the idea of all EFB's talking to each other - The Govt has gone some way to help us though. The rebate for ADSB devices is pretty good - this will show ALL traffic with an ADSB out on your Oz runways - don't know about AVPlan or Garmin or Foreflight or any of the other contenders. Not cheap - portable IN/OUT is > $1,000 before the rebate. Portable IN only is ~$450. Going to become compulsory in a few years if you want to fly into controlled airspace - not just Kingsford-Smith, but anywhere with a tower.

That requirement is from table 19 of the VFRG and quite correct, but MOS 26.13 on page 147 of the VFRG gives you some wiggle room depending on your certification. "Application – VFR flight requirements do not apply to certain light sport aircraft (MOS 26.13) Light sport aircraft for which a special certificate of airworthiness has been issued and is in force under CASR 21.186, or for which an experimental certificate has been issued and is in force under CASR 21.191, the equipment standards listed in Table 19 and Table 20 do not apply if the aircraft is fitted with equipment which provides a pilot with the same flight and navigation information." I don't know what your 19-XXXX type is but can be a LSA.

Nimitz was OK, Melbourne was tiny ....

Not an option - standard fit, as is electric flaps, electric elevator & rudder trim.

Yes. Similar stall speeds, similar cruise speeds. Not in an LSA and maintain a useful load and enough power to become airborne. Beg to disagree.

Gudday, Gotta be a high wing - Covid Vaccine left me a little gift in that I am no longer able to tolerate direct sun which is also why I have had to give away motorcycling and look for a new hobby. And yes, I know that some low wings have good overhead shielding but they are still hotter inside, hard to sit under or camp under and are just too hard to get in and out of when you get a little less supple. Flew a Piper something or other for 1 flight when I was getting my licence renewed after quite a long break from flying, and crawling under the wing on my hands and knees to do the fuel drain really convinced me, so the rest of the flights were in Cessnas. The 3 month build time is quoted by Ekolot (it's a factory build) assuming that all the electronics are readily available, and the 1 month transport is based on previous deliveries from the distributer here, though it maybe up to a week longer if the shipping still has to avoid the Suez by then. The other big holdup seems to be Customs in Melbourne. Still waiting for EASA to sign off on the new documentation for the shorter wing and spoilers before we can place an order. Until EASA certifies it, CASA won't automatically issue a Special Certificate of Airworthiness and we are not prepared to take the risk and order one until that come through. Unfortunately while we wait, their order book is filling up from people in countries that don't have our wonderful CASA looking after their wellbeing. EASA was supposed to be completed with the new documentation before Christmas 2023, but they have been a little busy with other stuff going on in the region. Went and talked to the Sling guys in Wentworth at Ausfly and I have lusted after the HW since I first saw it, but it's just on twice the price for not a lot of performance gain, I'm rarely going to have any passengers on the trips away and I'd have to build 51% myself.

My first trip to one of these type events and pleasantly surprised. Not sure what I expected but the stalls were all there for what I was looking for. I sat in on most of the seminars which were well presented and attended. The Saturday was very well attended by the general public seeing as it wasn't really an airshow and the display from the Freedom formation was excellent given the heat of the day and the blustery wind. And it was free ............ I can't comment for those that were underwing camping as I drove up and stayed in Wentworth.

747 would sound the caution if any button hadn't been pressed for 20 minutes (don't really exactly - may have been 25 minutes). Might sleep through a radio call - not going to ignore a bloody loud horn .....

OK - my bad - read the fine print and the $1M is coverage for the building. The $250K for a passenger seems light considering they could conceivably require medical assistance for a very long time. Going to have to get mine to sign a waiver .... Talked to the broker and he was very helpful explaining it.

Sorry - meant liability & not comprehensive. Doing my house & contents ins renewal at the same time - should not try and multitask ..... And the payout is limited to $1,000,000 where the aircraft insurance brokers are recommending $10M as a minimum with $20M as a realistic figure..
