The planes you mentioned have a higher gross weight than 1,232 lbs and exceed the VNE as well. You are mistaken. These aircraft fit the Light Sport classification in all respects. Rans Cyotee II - 540lb useful load Avid Aircraft Mark IV - 540lb useful load Zenith Zodiac 601 - 542lb useful load Fisher Dakota Hawk - 550lb useful load Sonex ltd. Sonex - 550lb useful load Aerocomp Merlin - 600lb useful load Capella XLS - 600lb useful load CGS Hawk Arrow 2 - 600lb useful load Skystar Kitfox Classic 4 - 650lb useful load Take 2 190 lbs adults, that 380 lbs, subtracted from 1,232 gives 852 lbs for the aircraft and fuel. Assume 26 gal of fuel, subtract 156 lbs from 852 giving 696 lbs for you plane. A 1969 Cessna 150 has a useful load of only 540 lbs. It has 22.5 gallons of fuel and a no reserve endurance of 4.1 hours. This gives a fuel burn of 5.5 gal/hr. The extra 3.5 gallons is unusable and makes up 21 lbs of the empty weight. A Zenith Zodiac has a very similar useful load of 542 lbs. Let's compare. 2 x 190 = 380 lbs. (for occupants) 22.5 x 6 = 135 lbs. (for fuel) 380 + 135 = 515 lbs. 540 - 515 = 25 lbs. (remaining) For the Cessna 150, full fuel would leave only 25 lbs for baggage. Now for the Zodiac. First we need to figure how much fuel we need to match. The Rotax 100HP 912S engine only burns 4.9 gal/hr @ 75 HP. 4.1 hours endurance x 4.9 gal/hr = 20.1 gallons 20.1 x 6 = 120.6 lbs. Let's round up to 121 lbs. 380 + 121 = 501 lbs. 542 - 501 = 41 lbs. (remaining) Compared to a Cessna 150, Zodiac: Has 16 more lbs. for baggage. Cruises 17 mph faster. Climbs 310 fpm faster. Has a wider cockpit. And is stressed to +/- 6.4 Gee's You can buy a Zodiac ready-to-fly today for $42,500 plus shipping. If Light Sport becomes law, this aircraft would be legal to fly already assembled. If a Cessna 150 is adequate then a Zodiac is more than adequate. This will change the value of a Cessna 150. |
