EFD Bonding Strap
An 8” or shorter braided bonding strap is required between the screw (below and left of
the static port- see Figure 6-8) on the backside of the EFD to a location on the backside
of the instrument panel using one of the mounting screws and nuts. Verify ≤ 3 milliohms
resistance to airframe ground at bonding strap connection point.

Pitot and Static Connections
Pitot and Static connections are made to the EFD1000 E5 via two keyed quick connect
fittings. These connections will typically require a “T fitting” to be installed in-line with
the existing altimeter and airspeed indicators.
The quick connectors are keyed such that they cannot be interchanged. Once the correct
quick connector is fastened to the pitot and static lines, they cannot be inadvertently
swapped on the rear of the EFD unit.
NOTE: The pitot quick connector will fit on the EFD static port but the static quick connector cannot
be inadvertently connected to the EFD pitot port due to the keying.
Each connector has a barbed fitting that accepts a 3/16” hose.
