One contributing factor to both these accidents may be a misunderstanding of the minimum altitude regulation. It is commonly described in internet discussions as " 500 feet ... except over water". But FAR 91.119 actually says "500 feet ... except over open water." (emphasis added)
Open water is not specifically defined in the FAR, but other FAA references such as the VFR sectional chart legend apply that term to large bodies of water such as oceans, bays, gulfs, and "exceptionally large lakes".
That's a really good point. I hadn't really noticed the distinction about open water before. Good catch with the chart legend.
However, like a lot of FAR's, there may be other factors to consider. The actual full text of that sentance is:
An altitude of 500 feet above the surface, except over open water or sparsely populated areas.
Anyone know if there is an official definition of "sparsely populated area? I suspect an argument could be made that a lake could constitute a "sparsely populated area".
