The aerodrome data in SkyDemon is not of poor quality. As you say, we include official data from AIPs for free inside SkyDemon. Because we include this free official data, we do not want to duplicate the data ourselves. There is simply no need to.
Perhaps you could elaborate and mention some specific airfields/situations in which you believe our data to be poor.
Certainly, it is our goal for basic information like runway lengths, surfaces and a PPR contact telephone number to be present in our database for all airfields.
