Narrow body“What are the infrastructural and operational narrow body ground handling concept specifications, based on the current KLM Boeing 737-800 ground handling turnaround process at AAS, such that in 95% of the turnarounds a turnaround time of 25 minutes is realized and the overall turnaround process reliability is improved?”

Wide body“What are the infrastructural and operational wide-body ground handling concept specifications, based on the current KLM B747-400 Combi ground handling turnaround process at AAS, such that in 95% of the turnarounds a turnaround time of 45 minutes is realized and the overall turnaround process reliability is improved?”

Possible advantages new concept KLM:– Direct cost decrease due to increase in aircraft utilization

(more “up-time”)– Extra flight(s) or less aircraft needed– Connectivity improvement (shorter minimum connecting time)– Interchangeable narrow body fleet– Punctuality improvement– Environment, safety, security, labour conditions, flexibility

Possible advantages new concept AAS– Increase in gate capacity– Punctuality improvement– Environment, safety, security, labour conditions, flexibility

The goal of 45 minutes turnaround time is not achieved reduction from 186 min to 116 min

Cabin process determines still the critical path activity catering

Reduction in turnaround time is not the motive for automation

The goal of 25 minutes turnaround time is not achieved reduction from 86 min to 50 min

Critical path is in the cabin: cabin cleaning

The requirements can be approached more when the business model would “ partly” change to from networked to “Point to Point -low-cost”

RecommendationsRecommendationsRecommendationsRecommendations

Continue the cooperation between KLM & Schiphol Continue the cooperation between KLM & Schiphol Further research to get more insight in variance of the

involved activities e.g. Lean theory

Investigate other aircraft types e.g. B777-300ER, A320

Investigate investments for design options e.g. co-innovation
