Challenges for Commercial Aviation

Flight Schedules Drive Your Business - They Should Drive Your Planning Too

Fleet availability and certified airworthiness are absolute requirements. The challenge? Few service supply chains serve as mobile an installed base of constantly changing assets over such broad networks. Generic planning tools cannot handle the volume, complexity and uniqueness of an aviation maintenance environment.

A full-spectrum solution incorporates the following capabilities:

  • Articulated aircraft configurations by fleet type or tail number
  • Part effectivity, supersession and criticality
  • Route projections or activity metrics by fleet type and station
  • Scheduled maintenance events
  • Initial provisioning
  • Probabilistic bills of material (BOMs) representing planned and conditional parts requirements

Don’t Let a Needed Part Ground You

Achieving flight schedules requires reliable fleet availability. In turn, fleet availability requires the right array of parts in the right places, both inside and outside of your network.

As the commercial aviation service supply chain becomes more multi-enterprise, the process for planning material requirements become more complex. Examples include:

  • Scheduled removals for big-ticket items like landing gears require coordination with the MRO.
  • Leasing arrangements with partner carriers create new sources of supply, and a web of new suppliers.
  • Repair shops spring up in response to new internal requirements for parts, base or line maintenance.

Flight schedules are the foundation of any material plan: they drive scheduled maintenance and influence random failures and unscheduled removals. When you understand route pairings by fleet type (or activity metrics of hours/cycles), you can tune parts optimization to your flight profile and quickly adjust when aircraft are reassigned to new routes. The as-flown configurations of each tail number provide great insight into the required parts and revisions. This knowledge dramatically increases the accuracy of the plan, reducing inventory exposures.

Many world-class carriers have leveraged PTC's solutions to reduce their overall cost per-flight-hour through reductions in overall inventory investment, maintenance delays for parts, and AOGs. Parts availability greatly contributes to cost-per-flight-hour.

Materials Management Can Be a Competitive Advantage


In aviation, successful materials management means avoidance of negatives – which is critical - rather than achievement of positives. Aircraft maintenance now requires a network of partners, all of whom rely on materials.

PTC software solutions prevent common yet significant problems. Having the right parts in the right places avoids delays and even cancellations, preserving revenue and customer satisfaction.

PTC’s algorithmic sophistication yields higher levels of parts availability while simultaneously lowering costs, which is important to both the maintenance and finance communities. Dramatic reductions in work stoppages due to lack of parts availability increase maintenance productivity and throughput resulting in reduced cycle times. Initial provisioning logic collaborates with major suppliers while pooling collaborates with flying partners. Long range planning avoids the accumulation of excess, limits exposure to obsolescence and avoids costly write-offs.
