Question 312: What are the most frequent results of an self-centred captain on the flight deck ?
A In a two-pilot flight deck, the co-pilot is ignored and may react by disengaging, showing delayed responses or aggression B Performance is very poor as self-centred behaviour leads to an increase of cooperation and efficiency C A major risk of authority inversion if the co-pilot is unassertive D High group performance despite the strained relations Explanation: NO Question 313: Which of the following statements are correct ? -1: Modern aircraft allow for 50 - 60% relative humidity in the cabin air under any conditions of flight, which is satisfactory for the body -2: Thirst is a belated symptom of dehydration -3: Dehydration may lead to clinical manifestations such as dizziness and fatigue -4: Drinking excessive quantities of water must be avoided since resistance to periods of low hydration will otherwise be lost A 2,3 B 2,3,4 C 1,2,4 D 1,4 Explanation: NO Question 314: With regard to central vision, which of the following statements are correct ? -1: It is due to the functioning of rods -2: It enables details, colours and movement to be seen -3: Its very active both during the day and at night -4: It represents a zone where about 150.000 cones per mm are located to give high resolution capacity A 2,4 B 1,2,4 C 1,3 D 2,3,4 Explanation: NO Question 315: Which of the following statements concerning information is correct ? A 70% of information processed by man enters via the visual channel B The kinesthetic channel provides the most important information for flying C 40% of information processed by man enters via the visual channel D Hearing is the sense which collects most information in man Explanation: NO
Question 316: What is the procedure above 10.000 ft altitude when faced with explosive decompression? A Don an oxygen mask and descend to below 10,000 ft B Check the cabin altitude, don an oxygen mask and maintain level flight C First inform ATC D Descend to below 10,000 ft and signal an emergency Explanation: NO Question 317: What is the approximate Time of Useful Consciousness for a seated pilot following a rapid decompression at 35,000 ft ? A 45 seconds B 3 seconds C 5 minutes D 12 seconds Explanation: The times quoted in most HPF notes are based on times given in a number of authoritative sources. From the feedback we receive from the exams it would appear that the examiner tends to go for slightly longer times. For 35,000ft we give 15 to 30 seconds. Of the four choices offered 5 minutes is far too long and 3 and 12 seconds are both too short for a seated pilot (implying no physical exertion). That leaves 45 seconds as the best of the four choices. Question 318: What is the Time of Useful Consciousness ? A The length of time during which an individual can act with both mental and physical efficiency, measured from the moment at which he/she loses his/her available oxygen supply B The period of time between the start of hypoxia and the moment that the pilot becomes aware of it C The time taken to become aware of hypoxia due to gradual decompression
