-
Diode-switching network.
Correct Answer
A. Diode-switching network.Explanation
The diode-switching network is the unit of the localizer course transmitter that provides a means of suppressing the carrier in the sideband only (SBO). This network uses diodes to switch the carrier on and off, allowing only the sideband signal to be transmitted. This helps to improve the accuracy and clarity of the localizer course signal by eliminating unwanted carrier signals. The exciter generates the carrier signal, the modulator assembly modulates the carrier with the navigation information, and the identification keyer adds identification signals to the transmission.Rate this question:

-
Integral detectors.
Correct Answer
A. Sampling loops in each log periodic dipole (LPD).Explanation
Sampling loops in each log periodic dipole (LPD) provide samples of the localizer radiated signals to the radio frequency (RF) combining network. These sampling loops are a crucial component of the system as they capture and measure the signals emitted by the localizer. By sampling the signals, the system can accurately determine the direction and position of an aircraft in relation to the localizer. The samples collected by the sampling loops are then fed into the RF combining network, where they are combined and processed to provide the necessary information for navigation and guidance.Rate this question:

Station assigned frequency (SAF).
-
Amplitude of the sidebands and carrier.
Correct Answer
A. Station assigned frequency (SAF).Explanation
The station assigned frequency (SAF) does not affect the difference in depth of modulation (DDM) for a localizer signal. DDM is determined by the amplitude of the sidebands and carrier, as well as the modulation and sideband and carrier phasing. SAF refers to the frequency assigned to the localizer station and is not directly related to the modulation characteristics of the signal. Therefore, it does not impact the DDM.Rate this question:

Tailoring the antenna power levels, a-spacing, and pair-to-pair phasing.
Correct Answer
A. Tailoring the antenna power levels, a-spacing, and pair-to-pair phasing.Explanation
In a single-frequency localizer, the course width is maintained at 5.0° by tailoring the antenna power levels, a-spacing, and pair-to-pair phasing. This means that the power levels of the antennas are adjusted, the distance between the antennas (a-spacing) is optimized, and the phasing between pairs of antennas is adjusted. These adjustments ensure that the signals from the antennas combine in a way that creates a narrow course width of 5.0°, allowing for precise navigation along the desired course.Rate this question:

Correct Answer
A. Above the runway threshold.Explanation
When operating an instrument landing system (ILS) at category II, the pilot must be able to fly inbound to a point of interception where the localizer course line intersects the glide path at a point above the runway threshold. This means that the pilot needs to be able to align the aircraft with the runway and descend to the correct altitude above the threshold before landing. The threshold is the beginning of the runway, so flying above it ensures that the aircraft is properly aligned and prepared for landing.Rate this question:
