As yourself this question.. Definitely much better than when it was first released though. Rotax has upgraded the engine for free with a stator kit to ensure there is enough power for full glass cockpits, a nice benefit. Just curious. Diesel engines from SMA, Thielert and Austro do a bit better than this at 0.35, but when mogas versus Jet-A or diesel prices are factored, the fuel operating costs for these engines are more comparable.

Even as the 912 iS was being announced last year, Rotax was already flying comparison trials, but the initial fuel economy data it released was based on dyno runs and some flight testing. Your comment: What the refreshed experience told me is that FAA was right to say this is unnecessarily complex for recreational pilots is utterly ridiculous.

Fly with an instructor, show your competency and get signed off. Having said that I chose FD 3 times in a row for some particular reason! Mitter said the test protocol called for trials on days of similar temperatures and density altitudes and defined run periods. [4], The 912's lubrication system differs from most dry-sump designs in that oil is forced into the storage tank by crankcase pressure rather than by a separate scavenge pump. Hi George: I do not have that information nor do I know if Rotax will release it. All three Rotax engines are offered by Tecnam because we believe they are all good viable choices.

The new 912 UL S is a 100 HP* version of the certified 81 HP 912 engine, with the same external dimensions as the standard Rotax 912. In power mode, it runs at about Lambda 0.8 or 0.9. Lubrication is dry sump, and fuelling is via dual CV carburetors or fully redundant electronic fuel injection. I wonder if this is the same defensive mechanism among maintenance personnel that used to be common back in the 70s and 80s when fuel injected cars were becoming the norm or do they know something about 912is we dont..?

[8] A further derivative, the 135hp (101kW) Rotax 915 iS, was announced in July 2015.[9]. The difference between the 912is and the ULS is the Induction system. The compression ratio is one thing the pressure inside the combustion chamber is another thing, in a turbo engine the the air is forced inside the combustion chamber in a normal engine is aspirated, thats why even at lower compression ratio the pressure inside a turbo engine is much higher. Without providing much detail, Rotax said the 912 iS is also capable Lambda 1.3 or lean-of-peak operation. In addition, Mitter collected broader data that showed that the 912 iS is slightly more efficient in climb than is the ULS. By [3] The 100hp (75kW) versions are used in many light sport aircraft, such as the Zenith STOL CH 701 and the Tecnam P2002 Sierra.

The electronic fuel injected Rotax 912iS is a recent development. Hence the push for single lever control, a simpler way to handle in-flight prop control. It does come with a few costs, as did the 912iS fuel injected engine compared to the 912ULS carbureted engine. This decision can be reversed. Toying with the idea of adding a second aircraft to my stable. That sounds dubious to me. Flight Design's base price on the 912 iS version of the airplane is $152,500 versus $139,800 for a comparably equipped 912 ULS CTLS. In all cases it has been the install, not the engine. by jetcat3 Sun Feb 26, 2017 2:01 pm, Post Great article! There was a crash of a Diamond Twinstar. Impressive but no more horsepower than the ULS and likely less in many conditions. Shaft with flange for fixed pitch propeller P.C.D. Once at altitude, Christian demonstrated use of the throttle and prop controls this was not a single lever control airplane to adjust for speed or economy. Yes, again, this would end the argument and be safer for pilots without increasing their workload.

Hi John: You are most welcome. Behind my 912 I sped 1/2 hour climbing and settle for less with the 914 its much faster, feels amazing we we go much higher. Thanks! If Mitters test data is confirmed by real-world results, they may well be proven right. Best speed for the 912i is at 7,500'DA Best speed for the 914 is prolly 16,000'. It got me thinking - The 912iS is Fuel Injected, the 914 is turbocharged but is back to dual carbs.

[I] was going to go with MT props, but they seem to be unresponsive. A back-of-the-envelope calculation reveals that these numbers rival diesel efficiency and if mogas is factored into the equation, flying a 912 iS-equipped aircraft is substantially less expensive than the equivalent 912 ULS. Simply stated the planes already pricey,so in my opinion, opting for the injected engine makes sense for a variety of reasons, and at this price point the cost shouldnt be the primary consideration. engine management system. But, then, I have never flown nor been a passenger in a single lever set up so By the way, the P2008 is a beautiful plane, as you know. But more air is added in the combustion chamber He also explained that (perhaps surprisingly to some readers) the 915iS compression ratio is lower to allow for the turbo boost. Michael is the key man behind the Aerotech/Rotax/Searey/MT Prop project to develop and refine a single lever control for light aircraft (see our video explaining this, or read our article).
