The biggest surprise was the amount of gear–avionics, flat panel EFIS, and accessories such as pitot heat, etc.–that some owners are packing into these airplanes. Because of this, the director of maintenance told me that LSA West has instituted a policy of automatically specifying an option on all Rotax-powered airplanes. The option is a 40-amp supplemental alternator since the standard system only supplies 20 amps.
The other option that they try to talk everyone into buying is carburetor heat. The twin carburetors on Rotax engines are mounted above and close to the water-cooled cylinder head–inlet air is drawn in from an area that’s in close vicinity to the exhaust system so carburetor heat is an option.
One advantage of LSA is that many more airplanes can be stacked in a standard sized hangar.
