The presentation of the Sentinel research as presented during the Airline & Aerospace MRO & Flight Operations IT Conference -Frankfurt,12th of June 2012

1. Human Interaction
with IT systems in
aircraft maintenance

Frankfurt, June 2012
Which role does it have in
continued airworthiness and
how does the future look?

2. Short intro
Sentinal research program:
Study into contribution of IT systems
and human interaction with these
systems to continued airworthiness

3. What my boss thinks I do What I think I do What I really do

5. Introduction (IST)
Computer systems and software have obtained a dominent level in airline
operations and thereby directly influence the airworthiness of aircraft
Problem:
Airworthiness of aircraft is nowadays safeguarded in automated IT systems.
These systems are operated and designed by human individuals and thus
liable to human error.
How big is the impact of human error liability in IT systems and
what can be done to mitigate the risk?

System availability
How big is the impact

12. • Digital data entry, data transfer, software creation, human-system
interaction and system availability are the new additional key-items for
continued aiworthiness.
• So what do the regulations say:
Regulations do not differentiate between digital information or paper /
classic model, only refer to “the system”
However, systems (e,g aircraft tech log registration) always requires
approval from the local authority
Based on what is the approval granted if no clear regulations exist…..????
How big is the impact

13. • Continued airworthiness has moved from human driven to computer
driven
• Traditional regulations are not umbagious to the digitalization of aviation
Good example: digital release of maintenance and electronic tec-log
How big is the impact
Digitization in Aviation is performed based on “best-abilities of people” and “best-
practice of industry” without any underlying norm, standard, regulation or
guideline to mitigate safety risks specifically related to digitization.

14. What can the industry do
• Integrate usage of systems and creation of systems into the current
existing risk mitigating and safety culture tools to increase awareness:
Dupont’s Dirty Dozen ExSyn’s 10 prevention measures
Short term:

15. What can the industry do
• Reduce human involvement in data entry / creation to the upmost
minimum

17. “the Aviation Cloud”

18. To summarize
• Continued Airworthiness Management has moved from human driven to
Computer driven
• Human error oppurtunities exist during intial data entry, transfer of data
between organizations, updating data, software creation and system
availability
• Traditional regulations are not established to take digitalization in
account (basically only one rule concerning data storage)
• Short term gain lies in dirty dozen theory to reduce human error in the
digital world of continued airworthiness
• Long term gain lies in a centralized airworthiness management system
“the aviation cloud”
