Paco Viry, a PhD candidate at the Institute for Sustainable Aviation, presented his research at the TSAS conference in Toulouse. His study, based on 30 years of air operations in North America and 56 different aircraft models, identifies three key factors in aircraft allocation to routes:
– Route length,
– Passenger flow intensity,
– Competition between models within the fleet.
Why does it matter?
Aircraft renewal does not follow a simple logic: an A380 can indirectly compete with a B737-800 through a complex chain of substitutions. Yet, allocation choices have a major impact as fuel consumption per passenger-kilometer can vary significantly, even between aircraft of the same generation. This research, which will contribute to the AeroMAPS platform, aims to better quantify fleet renewal and allocation dynamics to support decision-making for airlines, manufacturers, and regulators.
