Commercial aircraft cabin altitude

Effect of aircraft-cabin altitude on passenger discomfort.

BACKGROUND Acute mountain sickness occurs in some unacclimatized persons who travel to terrestrial altitudes at which barometric pressures are the same as those in commercial aircraft during flight. Whether the effects are similar in air travelers is unknown. METHODS We conducted a prospective, single-blind, controlled hypobaric-chamber study of adult volunteers to determine the effect of bar...

From Preliminary Aircraft Cabin Design to Cabin Optimization - Part I -

This paper conducts an investigation towards main aircraft cabin parameters. The aim is two-fold: First, a handbook method is used to preliminary design the aircraft cabin. Second, an objective function representing the “drag in the responsibility of the cabin” is created and optimized using both an analytical approach and a stochastic approach. Several methods for estimating wetted area and ma...

Physiologic effects of cabin pressure failure in high altitude passenger aircraft.

Experimental studies of thermal environment and contaminant transport in a commercial aircraft cabin with gaspers on.

Gaspers installed in commercial airliner cabins are used to improve passengers' thermal comfort. To understand the impact of gasper airflow on the air quality in a cabin, this investigation measured the distributions of air velocity, air temperature, and gaseous contaminant concentration in five rows of the economy-class section of an MD-82 commercial aircraft. The gaseous contaminant was simul...

Influence of cabin conditions on placement and response of contaminant detection sensors in a commercial aircraft.

Potential causalities due to airborne disease transmission and risk of chem-bio terrorism in commercial airliner cabins can be reduced by fast responses. Fast responses are only possible by using sensors at appropriate locations in the cabins. Cost, size and weight factors restrict the number of sensors that could be installed inside a cabin. Since release locations and seating patterns of pass...
