On top of that directed to try another runway (first time at this location). In a light sport it does all the work necessary at whatever altitude airport and density altitude operations plus it starts really easy, get's great fuel mileage for those long trips and has no instances of "rubber in the carbs". I have also reported that the agency made errors previously, such as demanding reciprocating engines (thereby inadvertently eliminating electric), and we are working to find remedies. Also, avgas is incompatible with the recommended synthetic oil which cannot hold lead in suspension; consequently, the use of leaded fuel mandates additional maintenance.[3]. It got me thinking - The 912iS is Fuel Injected, the 914 is turbocharged but is back to dual carbs. [3] The 100hp (75kW) versions are used in many light sport aircraft, such as the Zenith STOL CH 701 and the Tecnam P2002 Sierra.

Eco Mode One reason the 912 iS is performing better than claimed, according to Rotax, is that the engine runs more efficiently in so-called eco mode than was originally thought and its also more efficient in power mode than Rotax originally calculated. 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. The 912 iS ECU is programmed to run in eco mode at 77 percent power or less, at which point the engine will operate at what European engineers know as Lambda 1, or a stoichiometric air-to-fuel ratio of 14 to 1.
