Connection to the Pitot-static system
In order to display accurate speed and altitude data the Ultra needs to be connected to the
aircraft Pitot-static system. The Pitot and static ports on the back of the Ultra are equipped with
1/8" NPT female fittings. To connect the aircraft Pitot and static lines to the Ultra, you must use
standard 1/8" NPT male fittings at the end of each of the lines. Installation along with other
mechanical or digital altimeters and airspeed indicators is supported by mean of a T coupler
(not included in the Ultra box).
