1. A tire internal pressure management device comprising:
a data acquisition unit that acquires internal pressure time series data and temperature time series data of each tire mounted on a mobile body including an aircraft;
a representative value calculation unit that calculates a representative value of internal pressure data subjected to temperature correction for each predetermined period including a period from immediately after landing of the aircraft until a temperature of each tire becomes an outside air temperature, based on the acquired internal pressure time series data and temperature time series data; and
an internal pressure filling timing prediction unit that predicts a timing when an internal pressure value falls below a threshold value that is set in advance as an internal pressure filling timing, based on a transition of the calculated representative value of the internal pressure data.
