I am going to be setting up a new (TO me) glider panel during our fast approaching off season. Standard category if it matters and two of the things on the list are PowerFlarm and a Transponder. From talking to some people (Suppliers and other pilots) there are a few who are doing either or, and one who is forgoing the installation of a TX for a PF. Am I missing something? I have always thought you needed both the TX and PF. Have been flying with PF and so far it is doing a good job of detecting TX equipped gliders and power planes.
