ABOVE QUESTIONS WITH ANSWERS 


Question Number.    1.    Primary Radar is.     
Option A.    for ground use only. 
Option B.    reflected signal from aircraft's own radar. 
Option C.    interrogation of aircraft's transponder. 
Correct Answer is.    for ground use only. 
Explanation.    NIL.     


Question Number.    2.    A battery in situ on an aircraft charges at a fairly constant rate because generator voltage remains constant.     
Option A.    may charge slowly if initial battery voltage is low. 
Option B.    may charge at an excessive rate if initial battery voltage is low. 
Option C.     
Correct Answer is.    may charge at an excessive rate if initial battery voltage is low. 
Explanation.    NIL.     


Question Number.    3.    To parallel an alternating current generator with one or  more other generators, phase A must be.     
Option A.    in-phase with other generators and CBA only. 
Option B.    90 degrees out-of-phase and ABC. 
Option C.    in-phase with other generators and ABC. 
Correct Answer is.    in-phase with other generators and CBA only. 
Explanation.    NIL.     


Question Number.    4.    On an unparalleled twin generator alternating current  system, the phase of the second generator to be  brought on line.     
Option A.    must be in-phase prior to paralleling. 
Option B.    is important if the first generator fails. 
Option C.    is unimportant. 
Correct Answer is.    must be in-phase prior to paralleling. 
Explanation.    NIL.     


Question Number.    5.    When an autopilot is Fail Passive,.     
Option A.    the aircraft reverts to fail operational autopilot. 
Option B.    the pilot must resume control and land the aircraft. 
Option C.    the autoland can continue.

Explanation.    Pallett Automatic Flight Control p211.     


Question Number.    6.    On the direct current short shunt generator circuit shown, output voltage at the load is 200V. What is the voltage across the shunt winding?.     

Option A.    200V. 
Option B.    206V. 
Option C.    212V. 
Correct Answer is.    200V. 
Explanation.    The 10 ohm shunt, 0.06 ohm and the 0.04 ohm are the field windings. The generator output is split between the 0.06 ohm and the 100 ohm load, but only by 0.06/100x 200V = 0.12V (across the 0.06 ohm). So the voltage across the shunt winding is closer to 200V than the other two answers.
