weather data or engine instrumentation. It may also be used as a redundant display of
the flight instrumentation through the inter-display link. If a builder prefers dual AHRS
systems for redundancy, a second S200 should be used in place of the S100.
An internal GPS is standard in the Sport SX S200. Any external GPS may also be used,
as long as its serial data output is in one of the commonly used avionic formats. Most
GPS units will always transmit their flight plan, allowing the EFIS to display either the
GPS’s flight plan or its own internal plan. This ability is useful for adding IFR GPS
capability to the Sport system via an IFR-approved GPS navigator. Please note that only
the GPS functions will be transmitted via a GPS serial output, such as position, ground
track, groundspeed, flight plan, etc
… Other data provided to an external GPS (such as
weather) are not displayed on the GRT EFIS screen (unless this data is also available to
the EFIS, such as weather from an ADS-B receiver). Database information (such as
airport frequencies, runway information, etc
…) will always come from the EFIS navigation
database.
When the GRT Avionics Engine Information System (EIS) unit is connected to the EFIS,
its data is displayed on the EFIS screen. The EFIS enhances the usefulness of the engine
data by adding such features as an EGT time history, percent power and engine efficiency
(specific fuel consumption). The EIS may include its own digital display or may be fully
remote. The ENG page on the EFIS is dedicated to engine and environmental
parameters. Engine data can also be displayed on a portion of the primary flight display
page.
1-4: Integrating Third-Party Equipment
GRT Avionics differentiates itself from other manufacturers by embracing compatibility
with third-party equipment. This allows new technologies to be adopted quickly and gives
the owner the ability to take full advantage of the advances made in a competitive
marketplace. This includes equipment like Comm/Nav radios, transponders, ADS-B
transponders/receivers and many other devices. The addition of a second or third display
unit doubles or triples the number of available serial and USB ports, allowing for the use
of more third-party devices. The inter-display link between display units also allows for
data from most devices to be shared amongst the units for redundancy and convenience.
