I infer from this thread that the general view is that a pilot
(perhaps more so in low hours) has a higher potential to spin when
thermalling or attempting to thermal at less than 500' AGL than at
higher altitudes.
Additional to the pilot oriented aspects already noted by others, the
environmental factors also include:
- the disjointed nature of thermal convection at low level (Jorg Hacker
speculates that 1200' AGL is where thermal gusts get it together as a
single core)
- terrain variation is more obvious as obscuring 'horizon'
- where pilot experience is based on launches to greater heights than
this, low air time in this environment kicks in.
