Content:
How should you determine the amount of oxygen in a portable, high-pressure cylinder? Weigh the cylinder and its contents. Read the pressure gauge mounted on the cylinder. Measure the pressure at the mask.
Aircraft which operate only ac generators (alternators) as a primary source of electrical power normally provide current suitable for battery charging through the use of: a stepdown transformer and a rectifier. an inverter and a voltage-dropping resistor. a dynamotor with a half-wave dc output.
Which of the following is employed to maintain lateral stability when jettisoning fuel? Two separate independent systems. Crossfeed system. Two interconnected systems.
Under certain conditions, type A rivets are not used because of their: low strength characteristics. high alloy content. tendency toward embrittlement when subjected to vibration.
The purpose in checking main rotor blade tracking is to determine the: relative position of the blades during rotation. flight path of the blades during rotation. extent of an out of balance condition during rotation.
Superficial scars, scratches, surface abrasion, or rain erosion on fiberglass laminates can generally be repaired by applying: a piece of resin-impregnated glass fabric facing. one or more coats of suitable resin (room-temperature catalyzed) to the surface. a sheet of polyethylene over the abraded surface and one or more coats of resin cured with infrared heat lamps.
The vast majority of aircraft control cables are terminated with swaged terminals, that must be: corrosion treated to show compliance with the manufacturer's requirements after the swaging operation. pull tested to show compliance with the manufacturer's requirements after the swaging operation. checked with a go-no-go gauge before and after, to show compliance with the manufacturer's requirements after the swaging operation.
In the landing configuration GPWS typically monitors the radio (radar) altimeter; air data computer; instrument landing system; and: aileron, rudder, and elevator positions. landing gear and flap positions. spoiler, slat, and stabilizer positions.
What controls the amount of oxygen delivered to a mask in a continuous-flow oxygen system? Calibrated orifice. Pressure reducing valve. Pilot's regulator.
(Refer to airframe figure 16.) Which of the antennas shown is a typical glideslope antenna? 3 2 4.
Fuel boost pumps are operated: automatically from fuel pressure to provide a positive flow of fuel to the engine primarily for fuel transfer.
The general rule for finding the proper rivet diameter is: three times the thickness of the materials to be joined three times the thickness of the thickest sheet two times the rivet length.
What is the purpose of a float operated transmitter installed in a fuel tank? it sends an electric signal to the fuel quantity indicator it senses the total amount of fuel density it senses the dielectric qualities of fuel and air in the tank.
A hydraulic system operational check during ground runup of an aircraft indicates that the wing flaps cannot be lowered using the main hydraulic system, but can be lowered by using the emergency hand pump. Which is the most likely cause? the flap selector valve has a severe internal leak the pressure accumulator is not supplying pressure to the system the fluid level in the reservoir is low.
How can it be determined that all air has been purged from a master cylinder brake system? by noting whether the brake is firm or spongy by noting the amount of fluid return to the master cylinder upon brake release by operating a hydraulic unit and watching the system pressure gauge for smooth, full scale deflection.
The evacuation of a vapor-cycle cooling system removes any water that may be present by: raising the boiling point of the water and drawing out the vapor drawing out the liquid lowering the boiling point of the water and drawing out the vapor.
Which characteristics apply to aircraft hydraulic systems? 1. minimum maintenance requirements 2. lightweight 3. about 80 percent operating efficiency (20 percent loss due to fluid friction) 4. simple to inspect 1, 3, 4 1, 2, 3, 4 1, 2, 4.
Two types of hydraulic fluids currently being used in civil aircraft are: mixed mineral base and phosphate ester base mineral base, and phosphate ester base petroleum base and mixed mineral base.
Aircraft instrument panels are generally shock mounted to absorb: all vibrations low frequency, high amplitude shocks high frequency, high amplitude shocks.
(1) When servicing aircraft hydraulic systems, use the type fluid specified in the aircraft manufacturer's maintenance manual or on the instruction plate affixed to the reservoir or unit. (2) Hydraulic fluids for aircraft are dyed a specific color for each type of fluid. Regarding the above statements, only no. 2 is true only no. 1 is true both no. 1 and no. 2 are true.
A radar altimeter determines altitude by: transmitting a signal and receiving back a reflected signal means of transponder interrogation receiving signals transmitted from ground radar stations.
The lubber line on a directional gyro is used to: represent the wings of the aircraft align the instrument glass in the case represent the nose of the aircraft.
On some cabin pressurization systems, pressurization on the ground is restricted by the: main landing gear operated switch cabin pressure regulator negative pressure-relief valve.
What would be the effect if the piston return spring broke in a brake master cylinder? the brake travel would become excessive the brakes would become spongy the brakes would drag.
What is ventilating air used for on a combustion heater? carries heat to the places where needed provides air required to support the flame provides combustion air for ground blower.
A pressurization controller uses: barometric pressure, cabin altitude, and cabin rate of change bleed air pressure, outside air temperature, and cabin rate of climb cabin rate of climb, bleed air volume, and cabin pressure.
If it is necessary to use an electrical connector where it may be exposed to moisture, the mechanic should: coat the connector with grease use a special moisture proof type spray the connector with varnish or zinc chromate.
Why are aluminum plates 1/4 inch or more thick usually preheated before welding? reduces welding time prevents corrosion and ensures proper distribution of flux reduces internal stresses and assures more complete penetration.
When an empty shock strut is filled with fluid, care should be taken to extend and compress the strut completely at least two times to: ensure proper packing ring seating and removal of air bubbles force out any excess fluid thoroughly lubricate the piston rod.
How are generators rated? watts at rated voltage the impedance at rated voltage amperes at rated voltage.
How do deicer boots help remove ice accumulations? By preventing the formation of ice. By breaking up ice formations. By allowing only a thin layer of ice to build up.
Which statement concerning the 100-hour inspection of an airplane equipped with a push-pull tube-type control system is true? The threaded rod ends should not be adjusted in length for rigging purposes because the rod ends have been properly positioned and staked during manufacture. The terminal end threads of the turnbuckles should be visible through the safety hole in the barrel. The threaded rod ends should be checked for the amount of thread engagement by means of the inspection hole provided.
If a static pressure system check reveals excessive leakage, the leak(s) may be located by: pressurizing the system and adding leak detection dye. isolating portions of the line and testing each portion systematically starting at the instrument connections. removing and visually inspecting the line segments.
Why do most aircraft tire manufacturers recommend that the tubes in newly installed tires be first inflated, fully deflated, and then reinflated to the correct pressure? To allow the tube to position itself correctly inside the tire. To eliminate all the air between the tube and the inside of the tire. To test the entire assembly for leaks.
What should be the included angle of a twist drill for hard metal? 118°. 100°. 90°.
A fuel jettison system is required under certain conditions if the maximum takeoff weight exceeds the maximum landing weight. What regulations cover the requirements of fuel jettisoning? Federal Aviation Regulation Part 43 and 91. Federal Aviation Regulation Part 23, 25 and CAM 4b. Federal Aviation Regulation Part 21, 43 and CAM 8.
