They are easier to own and operate
They are easier and less expensive to own and operate than typical aircraft. With modern technology, they perform well and burn less fuel. Most of the new airplane LSA are designed to burn less expensive auto fuel. Generally, the lighter-weight sport airplanes go about the same speed of other small aircraft and burn about half the amount of fuel. In combination of running auto gas versus more expensive 100LL aviation fuel, the sport plane is below one-third the fuel costs to operate of the larger heavier general aviation airplane.
Speed and range
Fast speed (120 Knots) and heated/enclosed cockpits make an airplane the travel choice in the LSA category. With high-performance composite technology sport planes have almost 1000 mile range with 5 hours of fuel capacity. Besides being one of the most fun things to do, airplane LSA provide economical travel alternatives. Typically, LSA are flown under Visual Flight Rules VFR. Many, newer LSA can be flown under Instrument Flight Rules IFR, if properly equipped.
Some airplane LSA are known for the ability to fly low and slow, to see the earth from a different point of view. The LSA’s typical airspeed for slower airplanes is about 25-35 mph (40-60 km/h). You’ll typical operate at altitudes between 300 and 3000 feet (90-900 meters). But you can ground skim just a few feet off the ground (a popular use of the aircraft). These slower aircraft are primarily for fun flying. If you are thinking flying a slower airplane LSA is good, then you may also want to consider flying a trike weight-shift control LSA or a powered parachute LSA which are also slow yet more portable, and are less expensive to buy and maintain.
Overall, an airplane is the standard for aviation and the most popular for general aviation.
