4.5.1 GAE Installation
CAUTION
Make sure there are no pneumatic leaks. Make sure there is no fluid, sealant, or particles
inside the lines and fittings.
The installer is required to:
y
Fabricate static hose connections.
y
Label the hose near the unit.
y
Attach the aircraft static pressure source to the GAE.
Refer to section 3-1 for general guidance and installation information.
1. Secure the GAE to the GTX 335 back plate assembly with two screws.
2. Connect the wiring harness to the GAE.
3. Static System Connection
a. For aircraft with independent static systems and two transponders, the transponders should
be installed on different static systems. If no second static system is available, then it is
satisfactory to install transponders on the same static system.
a. Refer to the aircraft manufacturer’s documentation for pneumatic tubing and fitting part
numbers that can be used to connect the static system to the GAE female 1/8-27 ANPT.
Refer to 14 CFR Part 43 appendix E for approved practices to connect the GAE to the
aircraft static system.
a. Do not exceed the aircraft manufacturer’s minimum bend radius. Avoid routing near aircraft
control cables, structure, or high temperature lines, tubing, and components. The GAE must
not be the low point of the static plumbing lines, to avoid moisture or debris collecting at or
near the unit. The static line must be labeled near the unit.
a. Modifications must not interfere with the previously approved effectiveness of the static
system drains, the effectiveness of the alternate static source selector switch (if applicable),
or the independence of dual static systems (if applicable).
a. Modifications to the static port surface, aircraft surface near the static port, or other changes
that would affect the relationship between measured static air pressure and true ambient
static air pressure are outside the scope of this STC.
4. Refer to section 6 and section 7 for system configuration, calibration and checkout.
