The results of an experimental investigation on the human thermal comfort inside the cabin of someAirbus A319 aircrafts during 14 short-haul domestic flights, linking various Italian cities, are presentedand used to define a correlation among the predicted mean vote (PMV), a procedure which is commonlyused to assess the thermal comfort in inhabited environments, and the equivalent temperature andmean thermal vote (MTV), which are the parameters suggested by the European Standard EN ISO 14505-2 for the evaluation of the thermal environment in vehicles.The measurements of the radiant temperature, air temperature and relative humidity during flightswere performed. The air temperature varied between 22.2 °C and 26.0 ° C; the relative humidity rangedfrom 8.7% to 59.2%. The calculated values of the PMV varied from 0.16 to 0.90 and were confirmed bythe answers of the passengers. The equivalent temperature was evaluated using the equations of Fangeror on the basis of the values of the skin temperature measured on some volunteers.The correlation linking the thermal sensation scales and zones used by the PMV and the MTV resultedquite accurate because the minimum value of the absolute difference between such environmental indexesequalled 0.0073 and the maximum difference did not exceed the value of 0.0589. Even though theequivalent temperature and the MTV were specifically proposed to evaluate the thermal sensation invehicles, their use may be effectively extended to the assessment of the thermal comfort in airplanes orother occupied places.
