How can I verify the quality of the compensation?

A prerequisite for checking is that the flights are carried out in absolutely calm air (first gunlight and windstill). Test flights require some practice and the instruments should be recorded, if possible, by video camera. This helps to exclude emotional interpretations. In the normal case, esa systems probes and nozzles are well compensated and do not require any adjustment. The graphic helps to correctly interpret the vario readings. If the readings are not within the expected limits please check the following recommendations to isolate and eliminate the cause --> 'The vario compensation is not satisfying; what can I do?'
