Procedures should be established for the maintenance of the EFB system and how unserviceabilities
and failures will be dealt with to ensure that the integrity of the EFB system is assured. Maintenance
procedures will also need to include the handling of updated information and how this will be accepted
and then promulgated in a timely and complete format to all users and aircraft platforms.
Should a fault or failure of the system come to light it is essential that such failures are brought to the
immediate attention of the flight crew and that the system is isolated until rectification action is taken.
As well as back up procedures to deal with system failures a reporting system will need to be in place
so that any action necessary, either to a particular EFB system, or to the whole system, is taken in
order to prevent the use of erroneous information by flight crews.
The EFB system will need to be secure from unauthorised intervention. This should include the use
of password protected system updates as well as physical security of the hardware. Measures should
also include the control of laptop software installations to prevent use of unauthorised data.
7.5 Role of the EFB Administrator
The role of the EFB Administrator is a key factor in the running of the EFB system. He/she will need
to receive appropriate training in the role and should have a good working knowledge of the proposed
system hardware and operating system. The EFB system supplier should provide guidelines to
clearly identify, which parts of the system can be accessed and modified by the EFB Administrator
and which parts are only accessible by the supplier. It should also be clearly stated which changes
and modifications may be further delegated by the EFB Administrator to maintenance and support
staff. The EFB Administrator should establish procedures to ensure that these guidelines are strictly
adhered to and that no unauthorised changes take place. The EFB Administrator will also be
responsible for conducting audits and for ensuring that company procedures are complied with by all
personnel. This should include systematic audits/checks against the procedures and random checks
of reports to ensure that any detected errors are correctly followed up.
7.6 Flight Crew Training
Flight crew will need to be given specific training in the use of the EFB system before any approval is
given. Training should include at least the following:
• An overview of the system architecture
FLIGHT SAFETY FOUNDATION • FLIGHT SAFETY DIGEST • JUNE 2005 21

Section Four: Operations, Part Three: Temporary Guidance Leaflets (JAR-OPS)
Section 4/Part 3 (JAR-OPS) 36-11 01.10.04
• Pre-flight checks of the system
• Limitations of the system
• Specific training on the use of each application and the conditions under which the EFB may
and may not be used
• Restrictions on the use of the system, including where some or all of the system is not
available
• Procedures for cross checking of data entry and computed information
• Phases of flight when the EFB system may and may not be used
• CRM and human factor considerations on the use of the EFB
• Additional training for new applications or changes to the hardware configuration
Consideration should also be given to the role that the EFB system plays in Operator Proficiency
Checks as part of Recurrent training and checking.
7.7 Operational Evaluation Test
The object of the Operational Evaluation Test will be to verify that the above elements have been
satisfied before final approval of the EFB in place of paper documentation.
7.7.1 Initial Retention of Paper Back Up
Where paper is initially retained as back up, the operational evaluation test will typically be conducted
in two stages. The first stage should run in parallel with the equivalent paper format to verify the
correctness and reliability of the system. This will normally be for a six-month period but may be
varied at the discretion on the National Authority. The evaluation should include audits of the
procedures used as well as checks on the accuracy of any computed data. On completion of the first
stage a report should be sent to the National Authority who will then issue an approval for the use of
the system in place of the paper format. As a precaution, the paper documentation must be retained
during a second stage for use in the event of the EFB system not being available or any fault being
detected with the system. When the National Authority is satisfied that the back-up procedures are
sufficiently robust, approval may be given to allow removal of the paper documentation.
