61. Module 8 set 5 question # 6
Spoilers are interconnected with?
correct answer is Ailerons
Thank you. Corrected
62. 12) Low wing loading
a) increases stalling speed and maneuverability
b) decreases stalling speed and maneuverability
c) decreases lift and increases stalling speed,
the correct answer here is one which is not correct, if an aircraft has low wing loading it will have lower stalling speed and lower landing speed, reference LBP M8,pg 14,4th para. and if i'm wrong please correct me my exam is near..!
Yes, you are correct. low wing loading decreases stalling speed, landing speed and landing run. however it increases manoeuvrability. But airliners prefer high wing loading in order withstand turbulence. Thank you.. corrected

64. 2) What is absolute humidity?
1.The temperature to which humid air must be cooled at constant pressure to become saturated.
2.The actual amount of the water vapour in a mixture of air - water.
3.The ratio of the water vapour actually present in the atmosphere to the amount that would be present if the air were saturated at the prevailing temperature and pressure.
The correct answer is
the actual amount of water vapour in a mixture of air and water
Thanks for notifying, We will check the answer and let you know and do the necessary changes
65. With ISA conditions, what is the temperature at 30,000ft ?
A. Troposphere, Tropopause, Ionosphere, Exosphere
B.Stratosphere, Ionosphere, Exosphere Tropopause
C. Troposphere, Stratosphere, Ionosphere, Exosphere
this is a copy of the question and I don't think it has the correct answers for this question. Answers are not related
Thanks for notifying. it is corrected
66. 4) An aircraft travels at a constant speed of 800 km/h for 30 minutes. How far it would have traveled in 30 minutes?
In an hour it will travel 800 km. So in half an hour(30 min) it would travel a distance of 400 km. The answer should be 400 km.
67. The purpose of a patch cord used with an OTDR is
a. to compensate for any contraction of the Fiber optic cable during test.
b. to overcome the dead zone problem caused by reflection at OTDR launch connector.
c.to attenuate OTDR output power which could cause damage to the cable under test.
Optical Time-Domain Reflectometer (OTDR) is an optoelectronic instrument used to characterize an optical fiber. A patch cord is a length of cable, with connectors on the ends. At the same time, when the faults are masked in the length close to the OTDR is called "dead zone".
The patch code is used to overcome the dead zone problem.
68. Question from: Prathan
Radiant heat of a body, heated from a radiant source is
a. inversely proportional to the square of the distance.
b. proportional to distance.
c. inversely proportional.
Radiant heat, radiates out from a source, warm objects rather than the air. For example the heat you feel from a fire without touching it is due to radiant heating. As you move away the intensity of heat reduces. Further you move lesser you feel the heat. This is defined with the inverse-square law.
The Answer : A. inversely proportional to the square of the distance
69. Question from: Prathan
If heat is constant, and if pressure increases on a liquid what will the volume do?
According to Boyle's law, as the pressure increases the volume decreases when the system is at a constant temperature. The Boyle's law is only applicable for gases. Here the question is about the liquid, and liquids are usually incompressible. So the volume remains the same irrespective of pressure variation.
The answer is: Volume remains the same
70. If a tuning fork is struck and held close to the ear and slowly rotated about the vertical axis in one rotation how many times is there no sound?
In mediums which are fluid (e.g., gases and liquids), sound waves can only be longitudinal. So when the tuning fork is held near ear, sound can be heard, but when it moved up or down, the sound cannot be heard. In one rotation tuning fork moves up and back to ear and then down and back to ear. The sound cannot be heard twice ( one, when the fork is above the ear and second time when the fork is bellow the ear). Sound can heard only when the fork is near the ear.
