PITOT / STATIC CONNECTIONS
The connector kit supplied with the unit contains two (2) pneumatic quick disconnect fittings. These
fittings are specific to the connections on the rear of the unit and required for proper operation.
Aircraft tubing that connects to the unit must be ¼” OD with an approximate 0.17” ID. When determining
tubing length, be sure that it can extend through the cutout in the panel by approximately 8” to allow the
unit to be installed and removed from the front of the panel.
NOTE: It is helpful to identify/label each tube (pitot or static) so that it can be connected to the
correct port on the back of the unit during installation. WARNING: Lock quick disconnect before
connecting to the unit to avoid damaging the O-ring.
2.8 INSTALLATION
COMPLETION
Prior to operating the unit in the aircraft, verify the basic operation of the unit and conduct a standard leak
check of the pitot/static system per the aircraft maintenance manual or industry practice.
Configuration information is stored on the configuration module, allowing easy replacement of the MD302.
Because of this, the configuration module must be installed prior to applying power and configuring the
unit (See Section 3.1.)
Within 10 seconds after power is applied, the STAT (status) light should illuminate solid green. This
indicates normal operation. If the STAT light indicates RED, there is an issue preventing normal
operation. See Section 5.1.3 for details regarding operation and troubleshooting.
