Fuel Systems
What are two types of fuel cells used in modern aircraft?
Integral fuel cells (cells that are a sealed-off portion of the structure), and bladder- type cells.
What two types of antenna are used with most ADF receivers?
Sense and Loop type antenna
What happens when the Fire-Pull T-handle is pulled in a jet transport aircraft?
shuts down the fuel, hydraulics, and electrical systems, as well as bleed air to the effected engine.
What kind of clamp is used to secure a wire bundle to the aircraft structure?
a cushioned clamp Also known as Adel Clamp
What is the purpose of main landing gear torque links?
They keep the landing gear pointed in a straight ahead direction.
Where can you find the correct part number for the fuel quantity sensor to be installed in an aircraft fuel tank?
In the Illustrated Parts Catalog for the aircraft
How can you know when an ELT battery must be replaced or recharged?
By the date marked on the outside of the transmitter.
How can you determine the state of charge of a fire extinguisher container?
By the pressure shown on the built-in gage.
What is the maximum number of wires that should be connected to any single stud in a terminal strip?

What color is grade 100-LL fuel?
Blue
Where is the ELT transmitter normally located on an aircraft?
In the tail of the aircraft or as far aft as possible, so it will be least likely to be damaged in a crash.
How can you determine whether or not a built-in fire extinguishing system has been discharged?
By checking the blowout plugs on the outside of the aircraft near the extinguisher agent bottles
What are 3 types of circuit protection device used on Aircraft ?
Fuses, Circuit breakers and Current limiters
What power sources are normally used to retract landing gear systems?
Hydraulic or electrical.
Why are fuel tanks divided into compartments or have baffles installed in them?
The compartments or baffles keep the fuel from surging back and forth as the aircraft changes its attitude in flight.
What causes an ELT to actuate?
An inertia switch that detects an impact parallel to the longitudinal axis of the aircraft as would occur in a crash.
What is indicated if the yellow disk in a built-in fire extinguishing system is blown out?
The agent bottle has been discharged by the flight crew actuating the Bottle Discharge switch. -
Is an automatic-reset circuit breaker approved for aircraft electrical circuits?
No, a manual operation is needed to restore service after the circuit breaker has tripped.
What methods are used for transmitting cockpit control movements to a steering control unit in large aircraft?
Mechanical, electrical, or hydraulic.
Why is it important to drain all of the fuel sumps before the first flight of the day?
Water can condense in the fuel tanks and it must be drained out before the aircraft is safe for flight.
What is meant by a transceiver?
It is a piece of radio communications equipment in which all of the circuits for the receiver and the transmitter are contained in one housing.

Halon
How is a wire bundle protected from chafing where the bundle goes through a hole in a fuselage frame or bulkhead?
The edges of the hole are covered with a flexible grommet, and the bundle is secured to the structure with a cushioned clamp.
What type of nosewheel steering is provided on small aircraft?
A simple system consisting of mechanical linkage hooked to the rudder pedals.
