    2626As a good starting point it is useful to use the opposite flight direction flight lines to solve for roll and pitch. As a roll error will manifest itself as an across track shift and a pitch error as an along track shift. Be wary though that heading errors will also appear as a mixture of across and along track shifts. Heading errors are best identified using parallel lines with a 50% along track overlap.

     33=== Flight requirements: ===
     34
     35 * Multiple flight lines taken along different flight paths at different altitudes
     36  * Opposite and overlapping: e.g. a line North and a line South
     37  * Parallel and overlapping: e.g. 2 lines East
     38  * Ideally 4 or 5 lines each from at least 2 or 3 altitudes: 750m, 1350m, 2200m

     40Typically we will collect 11 or 12 lines going N, S, E and W taken at different altitudes.
