Airspeed and Altimeter
The existing airspeed and altimeter must remain in the original certified positions (basic T
configuration). Relocation is not approved under this STC.
The EFD1000 E5 should be connected to an independent pitot and static line
(independent of the existing pneumatic airspeed and altimeter) whenever available.
WARNING:
Failure to adhere to these specific instrument layout requirements and EFD1000 E5
configuration requirements will invalidate the STC.
4.4.5
Back Up Nav Indicator
For certification reasons a backup navigation indicator is required for at least one type of
operation for which the aircraft is certificated. This means that in any installation in an
aircraft certified for IFR where the EFD1000 E5 is the only display of navigation
information in the cockpit, a backup navigation indicator is required. This will ensure
that a failure of the EFD1000 E5 system does not result in a complete loss of all
navigation data to the flight crew.
Thus, for example, an installation that includes a panel mount GPS with an integral LCD
display that includes a CDI indicator approved for navigation would not require a backup
NAV indicator. However, a GPS with legacy VLOC radio that does not include an integral
display with CDI indications approved for navigation will require a backup NAV indicator.
If there is already a dedicated indicator wired to an existing NAV Receiver or GPS then it
can be paralleled to the ACU as shown in Section 9.
WARNING:
Failure to provide a backup NAV indicator when required will invalidate the STC.
CNX-80/GNS480
It is not recommended that a backup NAV indicator be connected. If it is desired to
connect a backup navigation indicator then it should only be wired to the dedicated VOR
Composite output on connector P7 of the CNX/GNS. Connecting the NAV indicator to the
AUX CDI output on P5 or to the Main Course Deviation output is not recommended.
4.4.6
Placards
All placards must be of a material that is not easily erased, disfigured, or obscured, and
securely adhered to the instrument panel.
The following placard is required and must be located near the EFD1000 E5 within the
pilot’s maximum field of view (see Figure 4-2). The placard must be in black and white
(white letters on black background or black letters on white background) in a font no
smaller than other placards in the aircraft and reads as follows:
If there are two GPS or two VLOC receivers installed in aircraft, label the GPS connected to
the EFD1000 E5 as “GPS1” and if a VLOC receiver is connected label as “VLOC1”.
ON BAT Dispatch Limit is 80%
