The "additional fuel to compensate" bit is misleading as well. There's only additional fuel needed if you are (a) actually using a bigger engine than planned (the above mentioned use of the standard 912S covers that), and if you're trying to meet a specific range target using that bigger engine (of which the LSA standards do not specify a minimum range requirement for certification). So if Icon is fudging the facts about that, what else are they trying to BS the FAA with?
