AMS 263 FINAL EXAM VERSION 1
When checking a Freon air conditioning system for leaks, use of flame-detection system strongly discouraged because - CORRECT ANSWER-lethal mustard gas can be produced
Which of these components of a Freon system removes the heat from the refrigerant an dissipates it into the atmosphere - CORRECT ANSWER-condenser
What is to be done if an aircraft on a 100 hour inspection program exceeds its 100 hour and is not inspected until 108 hours - CORRECT ANSWER-Eight hours must be deducted from the next inspection period, which would make the next 100 insection due in 92 hours 1 / 4

What is the condition of the refrigerant as it enters the condenser of a vapor-cycle cooling system - CORRECT ANSWER-high pressure vapor
What is the condition of the refrigerant as it enters the evaporator of a vapor-cycle cooling system - CORRECT ANSWER-low pressure liquid
The evacuation of a vapor-cycle cooling system removes any water that may be present - CORRECT ANSWER- lowering the boiling point of the water and drawing out the vapor
What is the condition of the refrigerant as it leaves the evaporator of a vapor-cycle cooling system - CORRECT ANSWER-low pressure vapor
In an operating vapor-cycle cooling system, if the two lines connected to the expansion valve are essentially the same temperature, what does this indicate? - CORRECT 2 / 4
- | P a g e
ANSWER-the expansion valve is not metering freon properly
(1) Water in a vapor-cycle cooling system will react with refrigerant to form hydrochloric acid which is highly corrosive to the metal in the system.(2) A small amount of water in a vapor-cycle cooling system can freeze in the TEV and stop the entire system operation.Regarding the above statements, - CORRECT ANSWER- only no. 1 is true
Which is considered a good practice concerning the inspection of heating and exhaust systems of aircraft utilizing a jacket around the engine exhaust as a heat source - CORRECT ANSWER-supplement physical inspections for carbon monoxide tests
When the crew manually closes the outflow valve in a properly operating pressurization system, the cabin pressure - CORRECT ANSWER-increases 3 / 4
- | P a g e
Where does the pressurizing air come from on most of the smaller reciprocating-engine-powered aircraft - CORRECT ANSWER -From the engine turbocharger
What determines the amount of pressurization that an aircraft can use - CORRECT ANSWER-The structural strength of the aircraft cabin
When the crew manually closes the outflow valve in a properly operating pressurization system, the cabin altitude - CORRECT ANSWER-decends
What normally keeps the cabin of a pressurized aircraft from being pressurized when the aircraft is on the ground
- CORRECT ANSWER-squat switch on landing gear
The operation of an aircraft combustion heater is usually controlled by a thermostat circuit which - CORRECT ANSWER-alternately turns the fuel on and off, a process known as cycling.
