Static tube installation
In order to utilize the full capability of the Raven 2 PRO an Indicated Airspeed (IAS) probe must be install
in the aircraft. The IAS probe must have two components, Ptot (total air pressure) and Pst (Static Air
pressure). Tubing from the Ptot probe and Pst probe needs to be connected to the Ptot and Pst ports on
the unit. Use only soft silicon tubing to connect to ports of the unit!
Inside IAS tubing set user can find one 3mm brass fitting where IAS probe can be connected. This fitting
must be installed in nose or on tail as high as possible to get as laminar air flow as possible. It must point
to the flight direction. Additionally, 2 x 2.5mm brass tubes for static intake on sides of fuselage are
located in IAS tubing set. Those tubes must be located where airflow around fuselage is in non-turbulent
area. We advise to install it in canopy area in front of wing on each side of fuselage. To connect all
together a silicone tubes and 2 x plastic T-jonts are included. Figure shows an example of how to
connect all components and to use electronic compensation for vario (Pte is connected to Pst). When
nd
normal TEK probe is used then connect Pte to TEK probe and do not use 2 T-joint.
