Safe VFR Flight Over the Top of Clouds

Image
Flight above clouds Our Zenith 601HDS plane, N314LB, is not equipped for flight under instrument flight rules (IFR). Nor do we have the appropriate rating for that kind of flight. Hence, we are restricted to visual flight rules (VFR). They demand that we cannot fly into clouds, let alone fly while embedded in clouds. VFR Cloud Conditions Below 10,000 ft MSL, VFR flight must be at least 500 ft below clouds or 1,000 ft above clouds, and horizontally must be at least 2,000 ft away from clouds. Above 10,000 ft MSL, two of the conditions are stricter: The 500 ft condition for flight below clouds is increased to 1,000 ft,  and the horizontal distance condition becomes 1 mile. The conditions are relaxed close to the ground: Up to 1,200 ft above ground level (AGL), VFR flight only needs to stay clear of clouds. Near airports, indicated by magenta shading on maps, that limit is lowered to 700 ft AGL.  The above summary is incomplete since it ignores conditions for night flight, w

Flying the Snake River

Image
Shoshone Falls of Snake River near Twin Falls, ID At 1,078 miles, the Snake River of the Pacific Northwest is one of the longest rivers of the US. Snake River (By USGS and modified by Shannon1 - Terrain data from DEMIS Mapserver , CC BY-SA 3.0) The river starts in western Wyoming. Southbound, the river flows along the eastern part of the Teton mountain range, swings around the southern edge of that range, and then proceeds northwest into Idaho. From there, it flows westerly in a long arc through that state. Finally, the river turns north, forming the border of Idaho and Oregon, and  empties into the Columbia River at Pasco, WA. Over the years, we have seen parts of the river on various trips. This year, we decided to fly along all of it save a small portion at the beginning and end.  This was a solo flight, since we have found that long flights over difficult terrain with a passenger entail too much distraction and thus impinge on safety.
