Fuel Systems
It is an emergency system provided so that the flight crew can quickly bring the weight of the airplane down to the maximum landing weight if an emergency occurs during or shortly after takeoff.
What is the purpose of a fuel dump system?
The length is the combined thickness of the materials to be joined by the rivet.
What is the grip length of a rivet?
A cable guide that routes a cable through the structure. It should not deflect the cable more than 3° from a straight line.
What is a fairlead?
Service the strut with dry nitrogen unless the aircraft maintenance manual specifically permits another gas.
What is used to inflate an oleo type landing gear shock strut?
A wire gauge (AWG) tool.
What tool is used to measure the size of unmarked electrical wire?
Bladder-type cells and integral (wet-wing) tanks.
What are two types of fuel cells?
depends on the bend radius, material thickness, and bend angle.
What factors are used to determine setbacks?
Install bolt heads up in vertical applications and forward in horizontal runs when practical.
When installing an aircraft bolt, what precaution would you take regarding the position of the bolt?
It is a unit designed to prevent nose wheel vibration or shimmy during taxiing, landing, or takeoff.
What is the purpose of a hydraulic shimmy damper?
A green light is mounted on the right wingtip, a red light on the left wingtip, and a white light is mounted in a position where it is visible from the rear of the aircraft.
What are the colors of aircraft position lights and where are they mounted?
Sight glass, mechanical (float/resistance), electrical, and electronic(capacitive).
What are the four general types of fuel quantity gages?
The line in the layout where the bend starts (transition from flat to radius).
What is the bend tangent line?
7×19 strand construction
What is the most common construction configuration of flexible control cables?
This item melt at a specified temperature and release air to prevent wheel/tire burst from heat-induced overpressure.
What is the purpose of the fusible plug in some aircraft wheels?
An excessive supply voltage or the motor field windings shorted.
What could cause an AC electric motor to run too fast?
To prevent the fuel from surging as a result of changes in the attitude of the aircraft.
What is the purpose of the baffles in a fuel tank?
A temporary, spring-loaded or threaded fastener inserted in drilled holes to hold sheets together until permanent fasteners are installed.
What type of device is a Cleco fastener?
To reduce continuous control forces required from the pilot.
What is the primary purpose of a trim tab?
A weight-on-wheels switch or sensor mounted in the landing-gear system that helps prevent gear retraction on the ground; its exact location varies by aircraft.
What is a squat switch and where is it located?
Insufficient insertion or over-crimping damages the conductor.
What are common causes of wire failure in a crimped connector?
An interconnected fuel system designed so that fuel can be fed from various tanks to any engine.
What is a cross-feed system?
Minimum 2 × rivet shank diameter from the edge.
What is the minimum edge distance allowed when installing rivets in a piece of aircraft sheet metal structure?
It is the Movable control surfaces on a V-tail airplane that are controlled by both the rudder pedals and the control yoke.
What is a ruddervator?
Three green lights on most aircraft.
What information is given to a pilot to indicate that all of the landing gears are down and locked?
When the voltage rises above the desired value, an electromagnetic relay opens and inserts a resistor in the generator field circuit, decreasing the field current and lowering the generator output voltage.
How does a vibrator-type voltage regulator maintain a constant voltage?
