43 Self Test Questions
Question | Answer |
---|---|
Information about non powered AGE can be found in which technical orders? | The 35 and 37 series technical orders. |
What are the basic parts of a maintenance stand? | A base assembly, upper structure assembly, platform assembly, and on most stands, a hydraulic system for raising and lowering the platform. |
How is the height of the platform adjusted on the B-1 Maintenance stand? | Hydraulic hand pump. |
Which maintenance stand is best suited for performing maintenance and inspections on the vertical stabilizer and rudder? | B-2. |
What should you ensure prior to standing on the ladder of a scissor-type maintenance stand? | Ensure safety pins are installed. |
What should you do with the wheels of a B-4 or B-5 maintenance stand before towing? | Lock the rear casters in the fore and aft position. |
How is the operation of the model 4000/4100 maintenance trailer controlled? | Hydraulically |
Other than transporting heavy loads, what's an additional use for the model 3000 transportation trailer? | Holding engines while inspections are performed. |
What can happen to an engine that has not been properly supported? | It may twist or bend, damaging the engine or its sub parts. |
Describe what the two-hand pumps are designed to do in a hydro mechanical jack? | The larger pump is used to raise the ram at a higher speed to meet the load. The smaller pump allows for greater ease of lift with a full load engaged. |
How do you control the speed of lowering a jack? | By the amount the release valve is opened. |
Tripod jacks are generally used for what procedures? | 1. Weighing an aircraft 2. changing a landing gear component 3. Repair a landing gear or gear component 4. Perform a landing gear retraction check. |
What are some of the uses of the axle jack? | 1. Tire Change 2. Brake Change 3. Wheel/bearing inspection and lubrication. |
Aircraft Oxygen systems are serviced with what two types of oxygen? | Gaseous(GOX) and Liquid (LOX) Oxygen. |
What are the properties of LOX? | A pale blue water like substances, that boils at -187 degrees Celsius or -297 degrees Fahrenheit. When warmed to a gaseous state, it expands to 860 times its original volume. |
How much LOX does the TMU-27/M LOX mobile storage tank hold? | 50 Gal. |
What is the pressure gage range on a TMU-27/M LOX mobile storage tank? | 0-100 PSI. |
What position should the pressure buildup valve on the TMU-27/M LOX mobile storage tank be in? | Closed. |
Why should LOX never be confined in any completely airtight piping or container? | Because it expands to approximately 860 times its original volume. |
What form is used to track all aircraft oxygen systems serviced with a specific LOX cart? | AFTO Form 134, Aviator Breathing Oxygen servicing trailer log. |
What is stenciled in white on the side of each high-pressure gaseous oxygen cylinder bottle? | Aviator's breathing oxygen. |
How many oxygen cylinder's is the AF/M32R-3 oxygen-servicing trailer designed to transport? | Eight. |
What is nitrogen used for on aircraft maintenance. | Pressure-operated mechanisms. |
Why is nitrogen the preferred gas for servicing aircraft systems? | Because it is an inert gas that doesn't form flammable or explosive mixtures with air or oxygen. |
The gaseous nitrogen cart is designed to use what method? | Cascading. |
What's the primary function of powered AGE? | Provide an auxiliary means of external power without operating the aircraft engines, APU, or internal systems to support maintenance. |
What happens to the waste product when the SGNSC separates the nitrogen from the air? | Enriched with 33% oxygen. |
What is the purpose of the MC-1A air compressor? | To provide high or low pressure clean, dry air for servicing aircraft pneumatic systems, hydraulic accumulators, also struts and tires. |
How much compressed air is the MC-2A air compressor capable of producing? | 15 CFM up to 200 PSI. |
How is heat increased or decreased on the H-1 Heater? | By allowing more or less fuel into the burner section. |
How is heating accomplished on the NGH? | By a 60 hz alternator that powers a separate oil burner and combustion blower. |
What is the temperature range of conditioned air provided by the C-10 air conditioner? | 47 to 200 degrees Fahrenheit. |
From where does the C-10 receive its source of air? | Hot bleed air from a gas turbine compressor. |
What's the electrical power output of the A/M32A-86 Generator? | 115/200 VAC, 400 Hz, 3 Phase. |
How much air is the A/M32A-60 capable of producing? | 150 pounds per minute at 50 psi. |
What source of power is used to start the A/M32A-95 generator? | A nickel cadmium battery, or two 12 volt gel pack batteries. |
How much electrical power can the FL-1D trailer-mounted floodlight produce? | 120 VAC, 60 Hz electrical power. |
How high can the mast on the FL-1D trailer-mounted floodlight be raised? | 12 Feet. |
How is power supplied to the MK-3A-3? | A 93 HP, 440 volt, 3-Phase, 60 cycle, 1,760 rpm electric motor with a two-stage start-split winding. |
