“СКАТ” system

Recorded parameters database:

Recorded parameters database contains information on the parameters to be recorded by the flight data recorders making part of particular aircrafts flight data recording system, and provides for entry and correction of composition, description, graduation and recording cyclogram of analog parameters and event signals. It is possible to open several databases at a time, as applicable.

Lying personnel database:

Flying personnel database contains the following information on pilots:

• Name.
• Call sign.
• Squadron.

The required data are entered into the flying personnel database at the stage of preparing the “СКАТ” system for putting into use and processing recorded data.

Aircraft fleet database:

Contains information on aircraft types and numbers according to the real configuration of aircraft fleet.
The required data are entered into the aircraft fleet database at the stage of preparing the “СКАТ” system for putting into use and processing recorded data.

The users database:

Provides:

• registration of system manager;
• registration of “CKAT” users with installation for everyone of the individual input password and the list of the permitted rights;
• users removal from among of registered ones.

The “СКАТ” software allows for time synchronization of the processing results obtained in different types. 

The “СКАТ” software allows for time synchronization of the processing results obtained in different types. While examining data processing results displayed in any form it is possible to browse the data in the following modes:

• in direct and reverse directions;
• in automatic mode-Start/Stop mode;
• in single-step mode;
• beginning from preset point of time.

Flight trajectory

Flight trajectory provides a means for representation of the processing results in the form of an aircraft movement trajectory with a possibility to make analysis from different viewing points and to change the picture scale. Flight trajectory is constructed in accordance with parameter values from flight information file. It is possible to display several flight trajectories simultaneously.
While examining data processing results displayed in the form of flight trajectory it is possible to use the following operations: 

• setting of sighting point and target tracking mode;
• map selection;
• map layers image setup;
• trajectory binding to a point on the map defined by user;
• trajectory origin and end points stitching;
• switching to 3-D aircraft attitude model;
• alteration of processing time gap.

3D aircraft attitude model

3D aircraft attitude model provides a means for representation of the processing results in the form of a dynamic three-dimensional image of aircraft with the indication of basic flight parameters (altitude, course, speed, pitch, and roll). Aircraft display image is formed in accordance with parameters values from the flight information file.

Dashboard

Dashboard provides a means for display of basic dashboard set pointer indicators readings. Instrumentation indications correspond to parameters values from the flight data file.

Graph

Results of flight data processing can be formed in accordance with the parameters of the current or standard (formed earlier) task with corresponding output attributes.

Table

Table provides a means for carrying out an accurate quantitative analysis of data and saving the results in various formats:

• in the form of the physical value of the assigned format or code;
• in a prescribed colour;
• in vertical or horizontal direction;
• with data decimation.

Proximate analysis module 

Proximate analysis module makes it possible to draw a conclusion on the technical condition of the aircraft, its systems and units, and also on flight crew actions during intervals between flights, following the algorithms from the Message Catalogues compiled by the aircraft designers. In order to acknowledge the events, revealed during the proximate analysis, “СКАТ” software allows for the reference information in the form of parameter graphs and “Reference-mode. Proximate analysis module provides processing of flight data recorded by more than one flight data recorders (BUR) involving unified database of the designed parameters.

Module for evaluation of aircraft test flight results

This module allows for automatic formation of the Test Flight Card by use of flight data received directly from the “СКАТ” software.

Module for recording of individual loading of components of type AL-31F engines

This module implements information support for change-over to operation of the engine according to its actual damageability.

Control module for monitoring of vibration in engines of type AL-31F

This module provides for timely detection of failures of the power unit.

Module of diagnostics and forecasting of a condition of inertial navigation system

Module of diagnostics and forecasting of a condition of a system of an automatic control

Engine diagnostic control module

This module makes it possible to carry out diagnostics of the combustion chamber, gas flow duct, fuel and oil systems, as well as engine vibration control, within the band of individual tolerances, by graphically representing and documenting the data both for individual flights and from flight to flight.
The modules used for control of loading of vertical stabilizers and outer wing panels, and for diagnostic control of engines, are ones of the most prospective trends in the field of development of flight data processing systems, because, using the mathematical tools, they allow for change-over from mere recording of a failure of one or another aircraft system to forecasting of such failure and its correction in proper time.

Vertical stabilizer and outer wing loading control module

1. This module makes it possible to make comparative analysis of loading degree of vertical stabilizers and outer wing panels by way of:

• computing the aircraft current mass, balance, and moments of inertia with due regard for different versions of external stores;
• determining maximum values of bending moments and computing their critical values in test cross-sections.

2. The module can give respective recommendations in the course of aircraft operation.
