The sensory memory length for sounds is about 1-2 seconds 2-4 seconds 4-8 seconds 8-15 seconds.
To develop under normal conditions after the lights have been turned off, full night vision requires 15-20 minutes 30-40 minutes 60-80 minutes about 2 hours.
The sensory memory length for visual images is about I second 10 seconds I minute 10 minutes.
The average number of items which can be held in the short term memory is 7 plus or minus 2 10 plus or minus 2 4 plus or minus 2 15 plus or minus 2.
A characteristic of the short term memory is that it is apparently visual acoustic spatial sensory.
Best night vision is achieved by looking slightly'off centre looking directly at an object eating lots of carrots using a bright torch to view the instruments.
Short term memory is of average susceptibility to errors very susceptible to errors error free almost error free.
Long exposure to very bright light can affect night vision for up to 6 hours I day 3 days I week.
Excess Stress can widen the attention range can restrict the attention range does not affect the attention range affects all individuals attention ranges the same.
The short term memory has a retention span of about 5-10 seconds 15-30 seconds 40-60 seconds 23 minutes.
The 'leans' can be caused by slowly entering a turn on instruments, followed by a fast wing levelling quickly entering a turn on instruments, followed by a fast wing levelling slowly entering a turn on instruments, followed by a slow wing levelling quickly entering a turn on instruments, followed by a slow wing levelling.
A bell-shaped curve of efficiency against stress shows that too high a stress level results in most efficiency and fun that too low a stress level results in most efficiency and fun that too high a stress level results in inefficiency and collapse that too high a stress level results in lack of interest.
The minimum noise level which will cause physical pain to the ears is 85 dB 110 dB 140 dB 165 dB.
The minimum level above which does noise starts to damage the ears is 60 dB 85 dB 110 dB 140 dB.
The normal sea level pressure is halved at an altitude of 10000 ft 18000 ft 25000 ft 30000 ft.
Our eyes start 'greying out' at a V loading of about 1.5 G 2.5 G 3.5 G 4.5 G.
We start to 'blackout' at a U loading of about 6.5 G 3.5 G 2.3 G 5 G.
A person's resistance to stress will best be increased by straining the whole system prescription drugs rest and relaxation adopting a positive fitness programme.
The three stages which have been identified in the progress of ones adaptation to stress are low, comfort, high resistance, alarm, collapse low, high, collapse alarm, resistance, collapse.
Attitude is caused by our thoughts colouring our perceptions and feelings which then influence our
behaviour a rational series of mind processes anything which reinforces our beliefs irrational prejudice wearing your baseball cap backwards.
The normal sea level pressure is doubled at a water depth of 22 ft 33 ft 55 ft 66 ft.
Empty Field Myopia is the tendency for the eyes to take up a resting focus position when there is
nothing to focus on, such as looking at an empty sky. The usual distance of the resting focus position in
front of the eyes is 1-2 m 20 m infinity 5-10 m.
The Three Circles Model of leadership shows the relationship between the attention areas of Duty, Emotion and Instinct Individual, Team and Task Leader, Follower and Colleague Leader, Follower and Colleague.
After crossing a number of time zones, the average rate of time adjustment the body makes is 10 hours per day 7 hours per day 4 hours per day 1.5 hours per day.
Malaria is a leading cause of death among pilots in third world countries like Haiti. The precaution
most effective as a preventative measure to guard against infection is prescription tablets which are completely effective as a preventative measure to always sleep under a mosquito net to always sleep in an air conditioned house to always wear long sleeves and trousers and use insect repellent spray.
One danger of using cold/flu relief medicines is that they may contain antihistamines, resulting in a feeling of well being and overconfidence hyperactivity drowsiness difficulty in getting adequate sleep.
Gout is a condition which can lead to arthritic attacks, especially in males. It is a result of a disturbance of the uric-acid metabolism lack of blood supply from a bad heart, causing an imbalance in the 02 :CO2 ratio excessive exercise/overworking, and a diet lacking in iron drinking too much water.
A pilot on a check flight performs a number of accurate landings during the check but then undershoots
during a landing. This error would be classified as random sporadic systematic consistent.
A pilot on a check flight performs a number of landings during the check but the touchdown point
varies without any recognisable pattern. This error would be classified as random sporadic systematic consistent.
A pilot on a check flight performs a number of landings during the check but undershoots in all cases.
This error would be classified as random sporadic systematic kinaesthetic.
A component of basic ergonomics is that the pilot must be trained to fit the cockpit the pilot should sit in a position from which all of the instruments are clearly visible the cockpit should be designed to fit the characteristics of the people who operate it the pilot's seat should be designed for maximum comfort.
If a passenger is hyperventilating an appropriate course of action would be encourage him/her to take deeper breaths administer oxygen encourage him/her to breathe slower or hold the breath administer oxygen and breathe deeper.
An action which would help prevent flicker vertigo is turn on the landing light when flying in cloud turn off strobes and rotating beacons when flying in cloud turn cockpit lighting down as dimly as possible keep the eyes focused on the instruments.
The best preparation for good quality sleep is activities that slow you down, a quiet dark room and a firm bed vigorous activity and music reading a book on human performance and limitations writing a long letter to a friend.
