Description of model parameters and variables.

SymbolRangeDescription

dDelay of a flight (d0 means d=0)

Max utility of a flight when its d=0

NNumber of flights operated by an AU in the reference period

Elasticity of the utility function of flight i. Used to model in a simplified way (continuous model) different operational flight margins

Probability of a flight i for being affected/delayed by a hotspot

Average delay expected for flight i in the route operated (i.e., typical delay from hotspots on that route)

Baseline (random) delay for flight i

Delay shift, to increase or reduce the delay of flight i

Optimal delay for flight i in the actual hotspot

Shifted delay, i.e., delay difference between the optimal delay and the baseline delay, for flight i
