Computer based training is now available to selected customers from Global Radio Support.

CBT format

All CBT training courses are based on the material presented in the corresponding Instructor led training courses.

A single CBT program can contain one or multiple courses, with multiple course format used when a student or student group will all be taking the same multiple courses.

The CBT program is designed to have a responsible Training Administrator. To execute the program the administrator is required to have a password, supplied by GRS. When the program has been installed, the administrator can log in with a personal password.

The Training administrator can access student information in the program. Information available to the administrator includes:
Student name
Student password
Student sign in date
Student progress through each course (In-process, passed or failed)
Student’s supervisor

With the program executed, students can log-on, sign-in, and create their own personal password for the training course. The student does not have to complete the training in one setting; they can stop and return later.

Each course has a printable Student Guide that each student can print our and use as they progress through the training program.

CBT programs can contain provisions for from 1 to 100+ student slots (we have not identified an upper limit). After the program has been delivered, GRS can increase the number of “student slots” available through a software change, completed by the on-site training administrator. Each CBT program’s student slot loading can be “increased” via software in steps of 1, 5, 10, 25 or 50.

Course Descriptions


005001. ARINC 429-I Training, Theory and Overview: A class similar to ARINC 429-II, but compressed for CBT application. The course is designed for the student involved in the testing and troubleshooting of ARINC 429 based systems or equipment. Simplex and bi-directional control schemes including the star and bus drop configurations are examined. 429 data words are analyzed for number of bits, parity, bit assignments, clock recovery, hi and lo data speed, and inter-word gaps. 429 cable specifications, cable length, impedance, terminations, 429 receivers, transmitters and addressing are covered. Testing and troubleshooting tips and suggestions are covered along with troubleshooting aids. The course includes two interactive troubleshooting practice examples.

005037. Mil. Std. 1553B-1 Training: A class similar to Mil Std 1553B-II, but compressed for CBT application. The course is designed for the technician involved in the testing and troubleshooting of Mil. Std. 1553B control based systems or equipment. The course begins with an overview of Mil. Std. 1553B and the terms associated with the standard. Bus architecture, is explained along with data priority and the modulation type used. The 1553 word format is cover in detail for command, data and status words including a bit by bit analysis, including sync and parity, of each word type. The course also covers signal, cable, receiver and transmitter specifications required for troubleshooting a 1553 controlled unit or system. Students receive practice in developing and interpreting 1553 words and receive aids to assist them in future troubleshooting. The course includes two interactive troubleshooting practice examples.

010043. RS-232/RS-422/RS-423/RS-485: These four data buses are covered in one class. The course covers the similarities and differences in signal specifications and use. The course covers the signal parameters and the protocol of each bus type. Interface circuits are presented and discussed along with specific signal specifications required for troubleshooting.

010026. ARINC 717 Training: A course for the technician involved in the testing and troubleshooting of Flight Data Acquisition and Recording Systems (FDARS). Students taking this course should have a thorough understanding of ARINC 429. The course reviews the FAA regulations requiring the use of FDARS on commercial aircraft. ARINC 717 course covers the interchangeability of equipment designed to meet the FAA requirement. Date acquisition is examined along with data ordering, reformatting, sampling rate, and sampling control. The ARINC 429 standard is analyzed. The data stored is analyzed, including Data Frames, sub-frames, sub-frame addressing, words, Modulation, waveforms and specifications. A complete system is examined to explain the functions of each LRU, the interconnects to the system and signals present on each interconnect pin.

005048. Have Quick I and II Training: This course provides students with an overview and the theory of Have Quick (HQ) I and II. Student learn the differences between; HQ I and II, training and combat modes of operation, word of day (WOD) and time of day and WOD and MWOD. During the course students learn the important aspects of training tables and frequency lists for both HQ I and II. Three methods used to obtain time of day (TOD) for an HQ radio are covered. The source of frequency hopping signals is explained along with an overview of synthesizers. The importance of frequency separation in HQ nets is explained along with the frequency separation specifications used for HQ. Students are provides with examples of both software and hardware related problems that may make it impossible for radios to hop together in a net.

010077. ATC Transponders Training: This course provides an overview of transponder equipment, theory and operation, and is intended for a student requiring a detailed knowledge of transponders. Transponder terms are presented and explained to provide a conversational knowledge of transponders. The airborne and ground portions of a transponder system are introduced, analyzed and explained. Transponder interrogation and reply pulses are analyzed to explain bit position significance and timing within and between signals. A block diagram theory of operation is presented to provide students with an understanding of the internal makeup and workings of a typical transponder system, including control and altimeter inputs. The ATCRBS functions of a transponder system are introduced and explained along with the airborne separation assurance (ASA) when it is interfaced with a TCAS system.
