Just some questions that i have been milling over in my mind since the systems exam the other week!!
Does anybody actually know what the answers to these would be?
In a modern Jet aircraft, landing forces are dampened by what?
A.Nitrogen and viscous fluid
B.Nitrogen
C.Hydrogen
D.Oxygen
are they talking about what supports the weight of the aircraft?.......then it would be nitrogen only............or are they talkin about the whole events during a landing.............in which case it would be nitrogen and viscous fluid!!!!!!
When leaning a mixture:
A: Fuel flow to the combustion chamber reduces
B: Airflow to the combustion chamber reduces
C: Fuel flow to the carburettor reduces
D: Airflow to the carburettor reduces
When you lean a mixture the fuel flow to the main jet reduces, therefore you can say that A is correct!!!
However, if you class the 'Main jet' as being a part of the carburretor then you could say that C is also correct!!:rolleyes:
After the power stroke, which valves are open?
A. Inlet
B. Outlet
C. Inlet and Outlet
D. None
So, theyre talkin about the exhaust stroke then! In which case the outlet valve is open!! However, during the exhaust stroke the inlet valve will also open!!! So what are they askin for???
What AIR:FUEL Mixture will allow the max EGT??
A..Near Idle cut off
B.. 1:9
C..1:1/15:1
D..Cruise settin
Yeah, algebra will tell you that C is the same as 15:1 and is the most probable answer, but is it really a fair question??? More of a trick to me!!!
What is shimmy?
A. potentially damaging vibration of the nose wheel
B. Movement of the nosewheel in the time between the input from the control wheel and the reaction of the wheels
Could be both id say.............there was definately not a definition in the available options that i had ever heard of!!!
No results today!:(
