  • Innovation



Innovative blueprints are shared with potential investors, launch customers or supportive peer groups to determine the frame of collaboration for MVP development.

The objective is to provide a solution with minimal features for early adopters to use and to prove the benefits and ROI. The MVP tackles the most important and most basic problems.

A better product is to be developed based on feedback and continuous cooperation.

The idea is to maximize learning and minimize the development cost and implementation risks.

Today there is no standard for CI calculations. Operating cost for CI calculations are provided by applying traditional cost value calculations. The re-/calculation cycles of CIs range from manufacture based recommendations per aircraft type, per season, quarterly, monthly, weekly, daily to per individual flight. The leverage of accurate operating cost for fuel and cost of time is not proven. 

The biggest error in calculating CI values undoubtedly comes from the miscalculation of operating cost. This is unlikely to be resolved until flight operations and financial departments of airlines cooperate.

XLM Aero is confident that significant savings are generated with an optimal CI based on accurate operating cost not only pre-flight, but also by taking in-flight cost drivers changes into account by providing the latest real-time operating cost for delays and misconnections. 

Proof of concept objective

Significant fuel and cost savings when an optima CI is calculated based on exact operating cost.

Expected results to be measured and verified: calculate an optimal cost index (CI) on a flight by flight basis with KEOPS CC and compare the results with the currently applied CI savings and values applied by an airline.

KEOPS CC has the ingredients ready for proof of concept (POC) or to provide a minimum viable product (MVP) demo. KEOPS CC is an activity based costing solution providing exact airline operating cost.

IRREG and cost impact prediction

Today airport collaborative decision making (A-CDM) is about airport individual departure management. Target off block times (TOBTs) are set by the handling party based on experience, not based on calculated, required or predicted turnaround times. A highly digitalized industry applies outdates times.

requires the ability to collaborate and share ideas with other people, and to sit down and talk with customers and get their feedback and understand their needs.

Minimum Connecting Time (MCT)

Apply MCT for reservation:

  • Day of OPS -> needed connecting time (NCT)
  • Day of OPS -> estimated connecting time (ECT)
  • Day of OPS -> required time of arrival (RTA)
  • Day of OPS -> required connecting time (RCT)

Minimum Ground Time (MinGT)

Appy MinGT for scheduling:

  • Day of OPS -> needed ground time (NGT)
  • Day of OPS -> variable ground time (VGT)
    according to steering activity applied
  • Day of OPS -> required ground time (RGT)

Static Taxi Time per airport / aircraft (STT)

Apply STT for scheduling:

  • Day of OPS -> variable taxi in and out time (VTT)

Framework - Status

Bad weather forecasts and their predicted impact on airport capacity are not published. The MET CDM process implemented in Australia is not an international standard.

ICAO Annex 14, Amendment 13 makes Runway Condition reporting compulsory for airport operators from November 2020. This is already enforced by the FAA in the US, with the use of the TALPA Matrix to determine Runway Condition Codes (RCC). ICAO Working Paper A 39-WP/286 19/8/16.

India presented a dynamic VTT calculation to improve the predictability of TTOT and TSAT. TTOT = TOBT + dynamic VTT.


With KEOPS CC worldwide airport charges are managed and calculated. In addition to the airport charges KEOPS CC++ can provide the airport status, MET and impact cost & condition predictions in one application for the airline’s network supplying OPS Control with best times and cost. KEOPS CC can be used as an impact calculation engine to analyze and track the impact of different scenarios and change to take the best economic decision in the OPS solution master system. With KEOPS CC rotation delays can be managed.


Provide the industry with a predictive impact awareness for better and more economic decisions complimenting the traditional master solutions. The provision of exact operating and irregularity costs generates significant savings.

Expected results to be measured and verified: compare the results of traditional cost and operations control results with the ones taken with KEOPS CC++. Document the cost savings and gains in passenger satisfaction and efficiency.

Lease management

Maintenance cost are provided by traditional costing solutions as maintenance cost / FH. Exact calculation and cost predictions are not covered by today’s Maintenance Planning and ERP solutions. Lease contracts, lease return, lease and maintenance cost management are managed in different solutions.

Imagination plus innovation equals realization.
