In what has been the most comprehensive study to date of the airflow of aircraft that has been made, The Department of US Defense. determined that the risk of contagion es practically non-existent in flight.
Study
in august 2020, a team made up of United, USTRANSCOM, DARPA and Air Mobility Command conducting a series of aerosol tracking studies simulating a suspected COVID-19 passenger aboard Boeing aircraft 767 and 777.
The test was designed to measure the penetration of particles into passengers' breathing zones while seated near and far from the suspected passenger., in this case a robot that simulated sneezing actions of a human being.
The different measurements were made at all stages of the flight, Pre boarding, boarding, filming, takeoff, cruise, landing and disembarkation, in order to measure the effectiveness of different aircraft systems, which together are equivalent to the distance of 2 meters recommended by the authorities, completing 300 tests, with 38 flight hours and 45 hours on land.
The result
When the passenger is seated and using a face mask, on average, only the 0,003% of the particles Infected air vents could enter your breathing, even when all the seats around you are occupied or the plane is completely full.
Rapid air recirculation on board, ventilation designed downwards and efficient HEPA filters, they make the cabin of a United airplane (and in general the industry) be one of the spaces safest closed doors in the world.
In this study, which has been the most complete to date on the possibility of contagion in flight, also determined that the 99.99% of particles were filtered out of the plane by the different systems applied and active on the aircraft.
