9. All placards that were associated with any/all gauges being replaced (non-limitation data) must
remain in the proximity of the EIS display.
10. Reused sensors must function through the sensor's entire range. For example, fuel tank floats may
have worn resistive elements that will result in performance issues with the gauge display.
11. If the aircraft POH or AFM has a fuel flow limit (i.e., red line), the installer must verify fuel flow
accuracy ±10% of the full scale range and adjust the K-Factor if necessary. Obtain the correct fuel
flow value using the engine or aircraft manufacturer manuals. If that data is not available, perform
a pre-installation static RPM ground check and document the pre-installation fuel flow using the
existing fuel flow indicator. Refer to Section 6.8.4 for post-installation K-Factor adjustment.
12. A single display that is a standalone EIS allows for the GPS connection to be optional. Standalone
EIS displays that do not have a GPS source connected will display dashes (---) for Fuel Endurance.
For cases where the standard gauge marking configuration cannot be used, aircraft-specific solutions for
unique gauge markings are provided in Appendix Section F.6.2.

If applicable.

Flow check may be required prior to de-modification; refer
to Appendix D.
Only required if existing gauge had colored markings,
alerts, and/or associated POH/AFM limitations.
AUX fuel quantity can only be displayed when main fuel
quantity is also displayed. GI 275 interface to fuel quantity
sensors is not approved in certain aircraft models. Refer to
Appendix D for model-specific information.
Only two of the four parameters may be gauges with
colored markings, alerts, and/or associated POH/AFM
limitations (the same parameter cannot be displayed
twice).
Configure if replacing an existing indicator. Optional if not
previously installed.
