Seems to me that the notion of power in a pilot study is moot. Typically, a
pilot study is a test of the research methodology and instruments. As such,
your sample size is a pragmatic decision and should consist of enough
observations to test your design and research instruments. For instance, if
you are planning to assess the psychometric properties of an instrument that
you are using, you need enough observations to meet the requirements of the
statistical tests you chose, such as Cronbach's Alpha or a Principle
Components. Power has nothing to do with this decision.
