Appendix J to TAA Advisory 2012-01

Operational Aircraft Evaluation

1.  Introduction

1.1   This Appendix provides details of an operational evaluation to ensure that operations can be safely conducted using the proposed EFB procedures. This evaluation may be combined with the installation evaluation described in Appendix D or conducted separately as circumstances warrant.

1.2   The scope of this operational evaluation may be greater than that provided below, dependent on the actual implementation. However, as a minimum the items listed below should be considered by the air operator. An associated checklist is contained in Appendix K. The operator is encouraged to create customized checklists as required.

2.  General operation

2.1   The guiding principle of operations with an EFB is that flights should be able to be conducted as safely with an EFB as with the methods or products that the EFB is intended to replace. The EFB should not add an unacceptable level of complexity for any critical activity or phase of flight. For systems with multiple EFBs, in the event of an output discrepancy, there should be a means for the crew to decide which output is correct.

3.  Workload

3.1   The implementation of EFBs should not cause a significant increase in crew workload, particularly during critical flight phases. Procedures should be put in place to minimize workload and prevent crew distraction. Factors which could increase pilot workload, such as loss of an EFB, should be considered.

4.  Installation Aspects Specific to the Operation

4.1   All aspects of the operator's proposed EFB procedures should be evaluated in the aircraft or a simulator representative of the aircraft to ensure that any installation issues specific to the proposed operation are identified and mitigated.

5.  Aircraft Performance Calculations

5.1   The operator should have a means to verify that the EFB outputs for aircraft performance calculations match the AFM. The EFB should have been determined during the installation evaluation to minimize the possibility of confusion and data entry errors. It should be confirmed that the operator's flight crew members using the operator's procedures find data entry to be easy and unambiguous. It should also be determined that the procedures allow for adequate crosscheck between crew members.

6.  Electronic Navigation Charts

6.1   It should be determined that crews are able to use the electronic navigation charts as readily as paper charts. The ability to easily select charts should be evaluated and the ability of the system to accommodate short notice changes, such as a change of runway, should be assessed. The possibility of crew confusion resulting from chart orientation, automatic chart selection or de-cluttering should be evaluated and mitigation should be proposed for any issues arising.

7.  Electronic Checklists

7.1   Electronic checklist features should be evaluated to determine whether crews are able to use them as well as paper checklists. The status of checklist items should be clear to the crew and it should be easy for the crew to change the status of each item. The potential to skip checklist items or assign incorrect actions should be minimized. The complete or incomplete status of the checklist should be clear to the crew.
