Beyond Linear Delay Multipliers in Air Transport

Figure 5

Normalised quadratic coefficient and airport properties. From (a) to (f), the six panels, respectively, depict the correlation between the coefficient and the size of the airport (number of operations); the airport standard delay multiplier; the average inbound (black squares) and outbound (green diamonds) delay; the entropy of the airline distribution; the entropy of the aircraft type distribution; and the number of flights per runway; see main text for definitions.
