APU Generator Output

This consists of one or more voltaic cells connected in series

It is the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position.

This occurs when a cell, or area within the cell, achieves elevated temperatures due to thermal failure, mechanical failure, internal/external short circuiting, and electrochemical abuse.

This consists of a CSD and AC generator

These are protective devices installed in an aircraft that "pops-out" when an abnormal surge of electrical power or shortage happens.

For maintenance technician communication with cockpit or cabin thanks to several jack connectors around the A/C.

It is the opposite of NOT Gate

These are instruments designed to constantly measure operating parameters relating to the aircraft's engine(s).

These cells remain sealed undenickel. cadmium cells are sealed with a high-pressure vent that releases only during abusive conditions.

It is the most basic of the GCU functions

101

Like any other part of an aircraft, the IDG must be serviced at regular intervals. Reasons for servicing the IDG include: refilling the IDG with oil, filling a newly installed IDG, adjusting the oil level, replacing the filter element, and replacing the cooling system.

ATA 34

It is the number of oscillations of a wave per unit time being measured in hertz (Hz).

These are gates wherein the inputs are inverted rather than inverting the output.

This makes interphone links between pilots themselves and the ground mechanic at the jack connection on the external power panel

To correct a cell imbalance during reconditioning the battery is typically discharged to zero capacity and then recharged

Shortest pointer value in altimeter

These serves as an alternate source of ambient tempreature

Requires low power

Gives the capability of tuning all communication radios

AC Generator Output

Output is at off when one and only one of its inputs is on. Otherwise, it is on.

This category covers a range of miscellaneous gauges and indicators not included in the first three groups that provide data on positions of moveable components on the aircraft, and the condition of various aircraft components or systems.

It is the surrounding pressure

Output is at logic 1 when, and only all its inputs are at logic 1, otherwise the output is logic 0.

These codes are assigned to aircraft operators and not to individual aircraft

These are systematic means of displaying binary data.

It is an equipment connected to accessory gearbox that maintains RPM for the use of the AC generator

SSR Stands for?

They perform basic logical functions that are fundamental to digital circuits

It gives the capability of tuning all communication radios

The RED mark in a Turn Coordinator means that the instrument has no _________

GPUs may be either portable or stationary units

It controls the channel and volume of transmission/reception.

Oil is only used for cooling and lubrication, but also plays a pivotal role within the CSD where it is used to automatically control the rotational speed of the generator.

These are the instruments that give information on the aircraft's flight attitude

It is the act of conveying meanings from one entity or group to another through the use of mutually understood signs, symbols and semiotic rules.

This converts DC to AC power

Airspeed is measured in _______

The heart of the audio system; directs the signals to and from the appropriate radio or interphone system.

It collects dynamic pressure for the use of the pressure type instruments in larger aircrafts
