1. Purpose and Applicability

This FSB report specifies FAA requirements applicable to operators seeking operations approval to use the ARINC Messenger (NavAero) Electronic Flight Bag (EFB) Class 2 device, under FAR 121.  Provisions of this report are consistent with the guidance defined in FAA Advisory Circular 120-76A and assume that appropriate airworthiness certification for installation of the EFB is/will be accomplished.


2. EFB Description

This installation consists of one ARINC Messenger NavAero electronic flight bag (EFB) at the Second Officer’s (S/O) station located directly behind (outboard of) the S/O’s instrument panel just aft of the area currently utilized for the First Officer’s (F/O) flight bag.  A thermal printer is installed on the aft structural support of the S/O’s instrument panel, directly to the right of the panel.  The EFB control panel will be secured to the forward edge (left side) of the S/O’s panel.  In addition to the cockpit equipment, an aircraft communication unit (ACU) ACARS unit will be installed in the E&E bay and a VHF antenna will be installed externally on the aft belly of the aircraft.

NOTE:  As part of the installation, the F/O’s oxygen mask location and ICS jack-box will be slightly altered.  There are no changes to existing operational procedures.

There are no operating limitations associated with this EFB mounting system.


4.  EFB Display Lighting and Reflectivity

4.1                    Display lighting.

This EFB has been evaluated in both low-light and full sunlight conditions. The display is readable under the full range of lighting conditions without distraction.

4.2                    Display Reflectivity.

The display has been evaluated during approach under night lighting conditions. There is no distracting reflectivity observed from the display under these conditions.

5 Typical Acceptable Operations Manual Procedures for Use of EFB

5.1       Normal operating procedures are included in the applicable airplane Flight Crew Operations Manual and Flight Crew Training Manual. Descriptions of specific applications may be contained in a “User Guide” supplied by the application vendor.

5.2       Non-Normal procedures:

If the 28VDC “S/O EFB” or “ARINC MSGR” circuit breakers should open during flight, the S/O is to leave the circuit breaker open (ARINC Messenger system will be repaired by ground personnel).  Make a logbook entry.

5.3       Limitations:

There are no Airworthiness Limitations associated with this installation.

6  Acceptable EFB Data Revision Process

6.1        TBD

7  FSB Specifications for Training and Typical Acceptable Training Course Description

7.1     General. As this installation currently encompasses ACARS type functionality only, initial training is set at Level B.

7.2      Programs Crediting Previous EFB Experience.   NA

7.3      Pilots Initial, Transition and Upgrade Ground Training

7.3.1        Pilots: Initial Training.   Initial EFB training is accomplished as specified by this FSB report or included in an approved AQP or airplane transition training program.  No unique provisions or requirements are specified.

7.3.2         Areas of Emphasis. None

7.4      Recurrent Training

7.4.1        Recurrent training is not normally required for EFB operation provided the functions are used regularly in line operations.  Operators are encouraged to include EFB as a component of simulator recurrent training to the extent practical.

7.4.2         As part of an approved training program, an operator may use many methods when conducting recurrent training, including classroom instruction, pictures, videotape, ground training devices, computer-based instruction, and static aircraft training.

7.4.3         Recurrent Training Simulator Requirements (reserved)

8  FSB Specifications for Checking

8.1       Checking Items.   No specific checking requirements have been identified at this time.  Operators are encouraged to include EFB use as a part of recurrent checking where practical.  Proper EFB use should be included in line checks.

8.2       Areas of emphasis.   The following areas of emphasis should be addressed during line checks as necessary:

8.2.1              TBD

8.2.2              TBD

8.2.3              TBD

8.2.4              TBD

8.2.5              Proper cross-check of data entered into the performance application

8.3       Proficiency Checks/Practical Tests. At the discretion of the evaluator, and if the EFB is installed in the operator’s training device or simulator, EFB may be included in the practical testing and annual proficiency checks.

9  FSB Specifications for Currency

9.1                Assuming EFB is used regularly , no unique currency provisions apply to the EFB.

10 Electromagnetic Interference (E.M.I.)

The ARINC Messenger EFB (including the power supply) has been tested by ground and flight testing in accordance with procedures contained in ARINC Document No. 23-06-0001-20, Revision: 1R.  The ARINC Messenger EFB has been found not exhibit any unacceptable levels of electromagnetic radiation.


Changes of any of the components listed in paragraph 2.3 will require that the EFB is checked again for acceptable levels of EMI.

11  Rapid Depressurization Testing


The effects of rapid depressurization have been evaluated for this EFB installation in accordance with Advisory Circular 25-10.

12  Operating System Change Requirements

Changes to the Windows operating system that involve .exe, .dll files or Java scripts will require that the operator notify the FAA Principal Inspector that the operation of all approved applications continues to meet intended function.

13  Configuration Control

The certificate holder or the operator will need to satisfy the Principal Inspector that they have procedures in place to manage the hardware and software configuration of any Class 2 EFBs that will be in operational use.

14  Instructions for Continued Airworthiness

The certificate holder or the operator is responsible to demonstrate that they have procedures in place to track repairs to EFB units and to ensure each EFB remains in compliance with the approved configuration.

15  Compliance Checklist

15.1   Compliance Checklist (see Appendix 2).

Compliance checklists are provided as an aid to identify those specific rules or policies for which compliance has already been demonstrated to FAA.  The checklist also notes rules or policies which must be demonstrated to CHDOs by the operator.  Not all rules or policies or variants are necessarily listed or addressed.

15.2   Discussion of Specific Compliance Checklist Items (reserved)

16  FSB Specifications for Devices and Simulators-(Reserved)

17  Application of FSB Report

Relevant parts of this report are effective for the specific combination of Class 2 EFB and mounting system when the report is approved by FAA.

18  Alternate Means of Compliance

18.1  Approval Level and Approval Criteria.  Alternate means of compliance to the provisions of this report, must be approved by AFS-200.  If alternate compliance is sought, operators will be required to establish that any proposed alternate means provides an equivalent level of safety to the provisions of AC 120-76A and this FSB report.  Analysis, demonstrations, proof of concept testing, differences documentation, or other evidence may be required.

18.2  Requires Equivalent Safety.  In the event alternate compliance is sought, training program hour reductions, simulator approvals, and device approvals, may be significantly limited and reporting requirements may be increased to assure equivalent safety.  FAA will generally not consider relief through alternate compliance means, unless sufficient lead time has been planned by an operator to allow for any necessary testing and evaluation.

18.3  Unforeseen Circumstances.  In the event of clearly unforeseen circumstances in which it is not possible for an operator to comply with report provisions, the operators may seek an interim equivalent program rather than a permanent alternate compliance method.  Financial arrangements, schedule adjustment, and other such reasons are not considered “unforeseen circumstances” for the purposes of this provision.
