Operational Needs<br />
Introduction to TATEM<br />
• <strong>Technologies</strong> <strong>and</strong> <strong>Techniques</strong> <strong>for</strong> nEw <strong>Maintenance</strong><br />
<strong>Concepts</strong><br />
• TATEM aims to tackle the 20% <strong>and</strong> 50% reduction in<br />
MRC by improving Aircraft Operability…<br />
• “Aircraft Operability is an aggregate measure of the<br />
aircraft's availability, operational reliability <strong>and</strong><br />
maintenance related costs…”<br />
• What is innovative about TATEM<br />
• Scope + integration + prognostics = a revolutionary effect…<br />

Operational Needs<br />
Underst<strong>and</strong>ing the operational needs<br />
1. Punctuality: ensure scheduled revenue flights<br />
CHALLENGE: Avoid operational interruptions due to aircraft failures,<br />
damages or servicing tasks<br />
2. Higher utilization: maximize the time where the<br />
product can be operated<br />
CHALLENGE: Avoid down-times where the aircraft cannot be<br />
operated due to maintenance<br />
3. Lower costs: minimize <strong>Maintenance</strong> Related Costs<br />

Higher Utilization<br />
•More robustness against defects<br />
•Pro-active maintenance<br />
•More flexible maintenance scheduling<br />
Punctuality<br />
•More robustness against defects<br />
•No maintenance during turn times<br />
•Rapid ground servicing<br />
Lower operating costs<br />
•Less fuel burn<br />
•Lower maintenance costs<br />

Operational Needs<br />
Top-Level Requirements (TLR)<br />
• 30 TLRs were defined, from which 19 are related to Health<br />
Management<br />
• TLRs provide a guidance framework to the research<br />
Str<strong>and</strong>s<br />
• TLRs can be used as theoretical inputs (virtual research<br />
results) to the benefits assessment so as to know what<br />
could be the ultimate achievable benefits if TLRs were fully<br />
fulfilled by the project<br />
Remark: as our underst<strong>and</strong>ing of TATEM concepts<br />
continuously improves, some TLRs will be revised<br />
where appropriate<br />
