Trapped Gas in Humans
This is any volume of trapped gas in the human body unable to equalize with ambient pressures.
Trapped Gas
Decompression sickness is caused by the evolution of bubbles of this gas in the body.
Nitrogen
These contaminants are brought into the cabin through the ECS system.
External Sourced Contaminants
A turn at or below this rate is considered to be below the sensory threshold.
3 degrees per second
Rarely is spatial disorientation a factor when flying under these flight rules in these conditions.
IFR in IMC
Barotitis Media is a blockage of this.
The Ear
The first cases of DCS were noted in these workers in the 1800s.
Caisson
Contaminants such as viruses, bacteria, and bioeffluents come from this internal contaminant source.
People
Vestibulo refers to these organs of the vestibular system.
Semi-circular canals and otolith
This dirty dozen factor breeds a loss of situational awareness.
Complacency
Barotitis Media is similar to this condition.
Barosinusitis/sinus block
Nitrogen bubbles form in the body in accordance with this gas law.
Henry’s law
Pyrolysis of chemicals is a contaminant from this source.
Aircraft Systems
Somaato refers to this.
Body
According to FAA research, pilots involved in SDO accidents have over this much experience.
1000hrs and 10 years
Gas in the body expands in accordance with this gas law.
Boyle’s Law
This is the least severe type of DCS.
Type I
This can be difficult due to smoke filled environments.
Egress efforts
Oculo refers to this.
The Eyes
This illusion typically occurs at night upon roll out from a sustained turn over 20 seconds.
Oculogyric
Pulmonary Barotrauma occurs because ascent is too
Rapid
An aircraft system that effectively prevents DCS is
Cabin Pressurization
Venting an aircraft could make a fire worse due to reintroduction of this.
Oxygen
This is the amount of our orientation the eye is responsible for.
90%
Elevator illusions occur because of this.
Unanticipated up or downdrafts.
