This parameter defines the frequency (in milliseconds) at which the Diagnostic

Interval

0 .. 1000000000

sequence will be executed. This sequence is used to retrieve the Diagnostic

 

Counter information and to read the Buffer Overflow Flag from the SRU.

 

 

 

 

A typical scan interval is 3600000 milliseconds (1 hour).

 

 

 

AI with time

No

This parameter is used to indicate if the analog input information is expected

 

Yes

to be received with or without time when the SRU is polled or when it sends

 

an unsolicited message.

 

 

 

 

NOTE: This parameter should match the way the device is configured

 

 

to report analog input information, otherwise the message

 

 

could be interpreted incorrectly and the DCA could report

 

 

inaccurate analog input information.

defined in the A197_PAR table. The range of partitions specified by this

 

 

 

Not Used (-1)

offset and the Number of Partitions must specify a valid range of A197_PAR

 

 

records.

No. of Partitions

0…255

This parameter specifies the number of records in the A197_PAR table that are

 

 

associated with this SRU. This value in combination with First Partition

 

 

parameter specifies the range of A197_PAR records that define the data

 

 

partitions for this port.

 

 

The default value is 0.

 

 

 

First System

Index into A197_SYS

This parameter specifies the first System Parameter definition record that is

Parameter

or

associated with this SRU. This offset must be less than the total number of

 

Not Used (-1)

records defined in the A197_SYS table. The range of partitions specified by

 

this offset and the Number of Parameters must specify a valid range of

 

 

 

 

A197_SYS records.

 

 

 

No. Of

0…255

This parameter specifies the number of records in the A197_SYS table that are

Parameters

 

associated with this SRU. This value in combination with First System

 

 

Parameter specifies the range of A197_SYS records that define the System

 

 

Parameters for this port.

 

 

The default value is 0.

X3.28 specifications

The GE X3.28 is a sophisticated commercial jet engine developed by General Electric, known for its innovative technologies and remarkable performance. Designed specifically for the next generation of regional jets, the X3.28 showcases an impressive blend of efficiency, reliability, and low emissions, setting a new benchmark in the aviation industry.

One of the standout features of the X3.28 is its advanced turbofan design, which combines a large bypass ratio with cutting-edge materials to enhance performance while reducing fuel consumption. The engine is built with lightweight composite materials that not only improve fuel efficiency but also contribute to overall weight reduction in regional aircraft. This is crucial for smaller jets that rely on maximizing payload while minimizing operational costs.

The X3.28 is equipped with an innovative high-pressure compressor system that utilizes advanced aerodynamics to ensure optimal airflow and pressure ratios. This technology enhances the engine's thrust performance, allowing aircraft to take off and climb efficiently even from shorter runways. Additionally, the fan blades are designed using state-of-the-art computational fluid dynamics simulations, which help in achieving higher performance and operational reliability.

Another significant characteristic of the X3.28 is its noise reduction capabilities. By employing advanced sound-attenuating technologies in the fan and exhaust systems, the engine meets stringent noise regulations, making it suitable for operations in urban areas and near sensitive environments. This focus on environmental considerations extends to its low emissions profile, making it a more eco-friendly choice compared to older engine models.

The engine also incorporates digital monitoring and control systems that provide real-time data on performance metrics, enabling more efficient maintenance scheduling and enhanced operational safety. This predictive maintenance approach helps airlines reduce downtime and streamline their operations, ultimately contributing to cost savings.

In summary, the GE X3.28 stands out in the competitive market of regional jet engines due to its advanced technologies, exceptional efficiency, and commitment to sustainability. With its focus on performance and environmental responsibility, the X3.28 is poised to lead the way in the future of regional aviation, making it an attractive option for airlines looking to modernize their fleets while maintaining operational excellence.
