AMTBLK06 Final A

terms are used when two waveforms go through their maximum and minimum points at different times to describe the phase difference?

• lead and lag

• capacitive and inductive reactance

• positive peak 90/ negative peak 270

phase shift created by inductive reactance always causes voltage to

• lag current

• lead current

• remain in phase with current

choice that best completes the statement or answers the question. An example of SWAMP area for aircraft wiring

• Storing aircraft in a dry environment has eliminated the environmental exposure to aircraft wiring

• When aircraft enter MRO’s for inspection, the facility will inspect the wiring for SWAMP exposure

• near wing flaps, wing folds, or pylons

VHF communication transceivers are coupled with VOR receivers, called

• NAV/COM radios

• VOR/VHF transceiver

• VHF radios cannot be coupled with VOR receivers, one is for voice and the other is navigation only

Identify the choice that best completes the statement or answers the question. Whenever troubleshooting aircraft electrical circuits, it is always valuable to consider Ohm’s Law

• Ohm’s law is of little use in troubleshooting, always consult the manufactures drawings.

• remembering that a low resistance means increased current and can explain why circuit breakers pop or fuses blow

• The law was named after German Physicist George Simon Ohm

wire type can be severely damaged on the inside without any evidence of damage on the outside?

• PTFE wiring

• ETOPS wiring

• coaxial cable

Identify the choice that best completes the statement or answers the question. While starting the engine the starter can often draw 100 or more amperes, for this reason, a. all starter motors are controlled through a solenoid b. all starter motors must be brushless DC starters. c. all starters must be shunt wound starters

• all starter motors are controlled through a solenoid

• all starter motors must be brushless DC starters

• all starters must be shunt wound starters

Identify the choice that best completes the statement or answers the question. The Altitude Encoder convert the aircraft’s pressure altitude to a code and send to ATC from the transponder when selected to ALT. This system works between the altitudes of

• 1000 feet MSL- 40,000 feet MSL

• 1200 feet MSL- 100,000 feet MSL

• 1200 feet MSL-126,700 feet MSL

What BUS is directly connected to the battery?

• Main AC bus

• emergency AC bus

• hot battery bus

Why is it important for technicians to be aware of correct orientation of the ADF antenna?

• placement of ADF antenna is critical to a correct indication since it is a directional device

• the ADF antenna is omnidirectional and placement has no correlation to operation

• the received signal induces voltage that is sent to two stators in a resolver or goniometer
