EFB placement & workload
Position and display:
| Item | Rule | Cite |
|---|---|---|
| Viewing position | EFB in use (viewed or controlled) within 90 degrees either side of pilot's line of sight | AC 700-020 Appendix D, Hardware, Position (6)(a) |
| Flight-critical info needing immediate action (terrain/obstacle warnings, take-off/landing V-speeds) | In pilot's primary field of view | AC 700-020 Appendix D, Hardware, Position (6)(a) |
| Exception | Info not directly monitored from the EFB in flight, e.g. V-speeds only used to set bugs, airspeed indicator sole reference | AC 700-020 Appendix D, Hardware, Position (6)(a) |
| EFB display vs installed avionics display | Crew must tell them apart. EFB display is supplemental | AC 700-020 Appendix G |
| Positioning or database errors | Crew must report when visual checks reveal display discrepancies | AC 700-020 Appendix G, Training Requirements (1)(d) |
Critical phases (take-off, landing, others) and any phase:
| Phase | Item | Rule | Cite |
|---|---|---|---|
| Critical | EFB visual and auditory messages | Inhibited | AC 700-020 App D, Hardware with installed software, Messages (4)(a) |
| Critical | Required flight information | Stays presented. No uncommanded overlays, pop-ups or pre-emptive messages, except those indicating failure or degradation of current EFB application | AC 700-020 App D, Hardware with installed software, Messages (4)(a) |
| Critical | Data entry | Avoid complex multi-step | AC 700-020 App D, Workload (a) |
| Any | Flashing text or symbols in any EFB application | Avoid | AC 700-020 App D, Hardware with installed software, Messages (4)(a) |
EFB workload (AC 700-020 Appendix I, Workload (1)):
- Procedures in place to minimise workload and prevent crew distraction.
- Positioning, using, stowing: no significant workload increase, particularly in critical flight phases.
Trap: assuming EFB messages show in critical phases (they are inhibited), or treating the 90-degree limit as 45 degrees.
