The somatogravic illusion causes the pilot to think that - Select one: acceleration in level flight is a climb deceleration in level flight is a climb deceleration in a descent is level flight acceleration in a climb is level flight.
. If a pilot suspects that he/she is suffering the effects of hypoxia, the most appropriate remedy would be - Select one: voluntarily increase the breathing rate to increase the oxygen uptake voluntarily increase the depth of breathing to induce more oxygen into the lungs use supplemental oxygen or descend immediately to a lower level voluntarily increase both the rate and depth of breathing.
With reference to transmeridian dyschronism (jet lag), the following statement which correctly lists the worst conditions for biorhythm readjustment is - Select one: flying East (with the body system phases advancing) flying West (with the body system phases delaying) flying East (with the body system phases delaying) flying West (with the body system phases advancing).

Abdominal pain caused by the expansion of gases within the body is most likely to be associated with - Select one: a rapid descent in a high performance pressurised aircraft a rapid climb in a high performance unpressurised aircraft a rapid climb in a high performance pressurised aircraft a rapid descent in a high performance unpressurised aircraft.
At an altitude of 18000 ft the ambient atmospheric pressure is approximately - Select one: one half of its sea -level value one tenth of its sea -level value two thirds of its sea -level value one third of its sea -level value.
The primary cause of pilot incapacitation in flight is - Select one: stroke disorientation due to inner ear infections heart attack gastrointestinal disorders.
The sequence of transitions of G loads that would be most likely to produce G -LOC is - Select one: from a low positive to high positive G load from a high positive to high negative G load from a high negative to high positive G load From a low negative to high negative G load.
In the absence of reliable visual information, which of the following states of motion would be most difficult to differentiate? Select one: a rapid acceleration in level flight and a transition from level flight to a dive a rapid deceleration in level flight and a transition from level flight to a climb a rapid acceleration in level flight and a transition from level flight to a climb a steep turn and a rapid deceleration in level flight .
At a depth of about 30 feet, the underwater pressure is closest to - Select one: two times normal sea -level atmospheric pressure one and a half times normal sea -level atmospheric pressure one half of normal sea -level atmospheric pressure three times normal sea -level atmospheric pressure.

The most effective way to deal with an episode of disorientation in flight is to - Select one: rely absolutely on the aircraft's instruments keep a constant look-out for glimpses of the natural horizon outside disregard the instrument indications and fly by 'feel' until it passes keep the control column central and maintain constant power.
'The leans' is a state of disorientation which occurs when - Select one: the rate of onset of the initial bank angle is above the threshold of perception, and the rate of the pilot's correction to a level attitude is also above that threshold the rate of onset of the initial bank angle is above the threshold of perception, but the rate of the pilot's correction to a level attitude is below that threshold the rate of onset of the initial bank angle is below the threshold of perception, but the rate of the pilot's correction to a level attitude is above that threshold the rate of onset of the initial bank angle is below the threshold of perception, and the rate of the pilot's correction to a level attitude is also below that threshold .
