SUN - Mounting Adapter - 3-Function
The SUN mounting adapter has 3 ports to accommodate triple probes which sense pitot, static and TE (Total Energy). Many sailplane manufacturers build the SUN adapters into their aircraft. Probes that work with the SUN mounting adapter also work with the shorter UN mounting adapter. However, if probes that are designed for use with the SUN mounting adapter (such as carbon multiprobes MNIC/UN or DN/3-fach/UN) are used with a UN mounting adapter, it will work fine, but the collar on the probe will be located 20 mm from the tip of the mounting adapter. Therefore, the SUN mounting adapter is recommended for most applications.
