*2.2. Scenario Definitions*

This section introduces the individual scenarios for consideration at a regional airport of the future. These scenarios give an insight into which assumptions were made.

Based on the configurations and assumptions prepared by UNINA for the aircraft, these were further developed for the benefit of the regional airport. The flights of the HEA have been fitted into RTHA's flight schedule based on the following assumptions formulated by UNINA. Due to the COVID-19 pandemic, a flight plan from 2019 was used

because air traffic was not restricted in 2019. These data form the basis for the operation of the hybrid-electric aircraft in the scenarios of a regional airport of the future.


To calculate the energy required, an extra 330 km is added to the distance of 1111.2 km for any possible calamities (holding/diversion, etc.). Partly in connection with this choice, the gradual transition of aviation will accelerate the introduction of smaller but environmentally friendly aircraft with smaller passenger capacity. This may mean that aircraft such as a Boeing 737 will eventually be replaced by 2–4 environmentally friendly aircraft with a capacity of 50 passengers, followed by hybrid/electric aircraft with 100–150 passengers. For the first period, this means a severe increase in aircraft and flight movements at the airport. This will also have a massive impact on the infrastructure and organisation at the airport, with the comment that this transition will be gradual to allow the airport to prepare for it. Airport infrastructure is geared to existing aircraft for take-off, landing, taxiing, refuelling, loading/unloading, etc. Thus, it will change when adopting other disruptive aircraft propulsive technologies. The future regional airport infrastructure design focuses on the HEA, suitable for 50 PAX with a flight range of 1111.2 km.


In calculating the energy requirements in the different scenarios, a distinction has been made between typical mission (200 nmi) and design mission (600 nmi) flights. For all flights, the possibility of diversions, etc., corresponding to 330 additional km per flight has been included.
