Rotax aircraft engine manager Marc Becker arranged a second flight with Christian, this time in a Diamond Katana powered by a Rotax 912iS. Its expensive but in this case you get what you pay for and given the comfort, performance and reliability, its well worth it for us. The addition of a controllable pitch propeller may require a single lever control, at present a single lever control is not required. The lightest engine in the Rotax aircraft engine portfolio. Engine performance may vary depending on, among other things, general conditions, ambient temperature and altitude. Rotaxs 915iS uses the same displacement as the 912iS. I will cover many aircraft stories, but allow me to take the most recent first: flying the brand-new Rotax 915iS and comparing it to the 912iS, although not in the same airframe. Thanks again, love all the interviews and flight videos. The climb angle seemed vigorously steep, although this was my first experience in an Aquila aircraftso I had no basis of comparison. Marc Becker summarized, The 915iS is about 12 kilos (26 pounds) more for the engine only; 40-50 more pounds when installed and about 3,000 ($3,750 at todays exchange rates) more than the 914. It is significantly more than the 912iS, as you should expect for an engine with substantially more power and the ability to use that power up to higher altitudes. 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. Mitter said the test protocol called for trials on days of similar temperatures and density altitudes and defined run periods. This page was last edited on 3 December 2022, at 14:57.

Similarly, in cruise, the iS did better at low altitudes than Rotax originally calculated, but at higher altitudes8000 feet and aboveit did much better, showing as much as a 36 percent improvement over the ULS fuel burns. Looking forward to the fewer pneumatic synchronizations! At this setting the 914 is making a lot more horsepower that a 912. However, at the most basic level of Sport Pilot certificate, requiring only 20 hours of dual and solo, I dont believe a pilot should be reasonably expected to also learn about about in-flight prop adjustment; he or she may have no need or desire to acquire that skill. By comparison, the 912 iS appears to be running at about 0.36 to 0.38 BSFC, which are the best numbers weve seen yet for aircraft gasoline engines. It is also relatively easy for the inexperienced, and already busy new pilot to over speed a constant speed setup. Just pursue a PPL if one wants to increase the complexity, thats what its there for, and its not at all difficult to do. At altitudes needed for California cruising there's a 20kt difference.

Dry sump forced lubrication with separate oil tank, automatic adjustment by hydraulic valve tappet. I keep reading about 912 iS being a smoother running engine . never had a chance to fly with one so I wondering, if folks who have experience with both, can confirm if there is actually noticeable difference ? At thisstage of the LSA market, buying a carbd Rotax is truly short sighted in my view. Is Rotax similar? Please contact Just Aircraft. Ill have to ask if its possible. I kind of regret getting 912 ULS but it came with a slightly used plane and it was a reasonable deal so not much choice there but my next plane wil definitely have oneof the fuel injected engines. Forgive my ignorance, but if a 912 ULS or 914 UL engine loses electrical power, what happens to the functionality of these carbureted engines? Late to this party, I fly constant speed props and appreciate them. 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.
