Additional Practice Questions: Human Factors (Part 1): DGCA Air Regulations questions
The first extra practice set moves between the body at altitude and the way pilots take in information, handle stress and work as a crew.
Its 30 questions lean on hypoxia and hyperventilation, time of useful consciousness, cabin pressurisation and night vision, then turn to short-term memory, stress and the SHEL model. Exam sessions have included 5 of these questions.
In SHEL, a badly designed cockpit is a mismatch between Liveware and Hardware. Software means procedures, checklists and charts, so it is the wrong pairing. Your urge to breathe is driven mainly by the carbon dioxide level in the blood, not by a lack of oxygen, which is why hypoxia gives so little warning.
