  Electrification can help to reduce the carbon footprint of aviation. The
transition away from jet fuel-powered conventional airplane towards
battery-powered electrified aircraft will impose extra charging requirements on
airports. In this paper, we first quantify the increase in energy demands at
several airports across the United States (US), when commercial airline
carriers partially deploy hybrid electric aircraft (HEA). We then illustrate
that smart charging and minor modifications to flight schedules can
substantially reduce peak power demands, and in turn the needs for grid
infrastructure upgrade. Motivated by our data analysis, we then formulate an
optimization problem for slot allocation that incorporates HEA charging
considerations. This problem jointly decides flight schedules and charging
profiles to manage airport congestion and peak power demands. We illustrate the
efficacy of our formulation through a case study on the John F. Kennedy
International Airport.
