State the main difference between Primary and Secondary Cell batteries. (pick 1)

Primary discharges only once (e.g. Memory backup for GPS). Secondary cells can be recharged

Primary cells last for longer (CPU processor) and secondary cells can only be used once

Secondary cells can be recharged but primary cells can re recharged faster

Primary cells discharge instantly (e.g. Memory backup) and secondary takes a while to discharge

Describe thermal runaway

Thermal runaway is overheating caused by the breakdown of internal resistance (which in turn increases the current drawn). Self-destruction of the battery is possible.

Thermal runaway is the overheating of the aircraft battery due to moisture entering the hull (more in the 5A2)

Thermal runaway is the cooling of the battery due to an endothermic reaction in the surrounding air molecules

Heat escapes the aircraft battery and melts stuff

List the 5 types of AC power generation for aircraft

Generators, CPU’s, APU’s, Inverters or RAT’s

Generators, GPU’s, APU’s, Inverters or RAT’s

Generators, GPU’s, FWH’s, Inverters or RAT’s

Generators, GPU’s, APU’s, Inverters or MAT’s

The Generator Control Unit monitors 3 types of fault conditions, what are they

What is the purpose of the Generator Control Relay

The GCR remotely connects or disconnects the generator from the hydraulic systems

The GCR remotely connects and diffuses any components connected to the APU

The system reconnects all components to the Generator

The GCR remotely connects or disconnects the generator from the electrical systems

What device, normally under emergency conditions can provide AC power from a DC source

Inverter

TRU

Rectifier

APU

State one feature from primary bonding and another feature of secondary bonding (pick 2)

Primary bonding utilises the aircraft metal skin to form an earth-return path for both AC and DC systems

Primary bonding uses excess wires from the aircraft circuit to prevent surges

Secondary bonding is the bonding of surfaces that do not normally carry current but electro-static current

Secondary bonding is the bonding of wires that are less likely to heat up from current but instead electro static current
