CDC 2A354C Volume 1. F-16 Attack Control Systems

The correct answer is SNSR PWR panel. The SNSR PWR panel is where the CARA power switch is located.

The correct answer is that the forward CARA antenna transmits, while the aft CARA antenna receives. This means that the forward antenna is responsible for sending out signals, while the aft antenna is responsible for picking up incoming signals.

To prevent the FCR system from reentering the BIT (Built-In Test) during the operational checkout of the F-16C/D, the FCR switch should be placed back to the FCR position before the four-second time-out sequence is completed. This means that the switch should be turned back before four seconds have passed since the reinitialization process started. By doing this, the system will not go through the full BIT process and will continue with the operational checkout instead.

Each tic on the aircraft velocity scale represents a measurement of 10 knots. This means that every mark on the scale represents an increase or decrease of 10 knots in the aircraft's velocity.

The correct answer is "On/off brightness control switch on the JHMCS control panel." This is because the question asks specifically for the switch that would be used to power up the JHMCS (Joint Helmet Mounted Cueing System). The JHMCS power switch on the avionics power panel may control the overall power to the system, but the on/off brightness control switch on the JHMCS control panel is the specific switch that would be used to power up the JHMCS itself.

Radar antennas are designed to transmit and receive signals in a specific direction at any given time. This allows them to focus their energy and accurately detect objects within a specific area. By operating in only one direction at a time, radar antennas can effectively scan the surrounding environment and gather information about the location, speed, and direction of objects. This directional capability is essential for radar systems to function efficiently and provide accurate measurements and tracking.

The DMS (Digital Map System) is located on the side-stick controller. The side-stick controller is a control device used to manipulate the aircraft's flight controls. It is typically located on the side of the pilot's seat and is used to control the pitch and roll of the aircraft. Since the DMS is a part of the avionics system that provides digital maps and navigation information, it makes sense for it to be located on the side-stick controller for easy access and control while flying the aircraft.

If the active towed decoy system is installed, it would allow for a 12th display format to be possible. This suggests that the active towed decoy system has some impact on the display formats available to the user. The other options mentioned, such as loading an ECM pod or completing a time compliance technical order, do not have an effect on the availability of display formats. Therefore, the correct answer is the active towed decoy system being installed.

The correct answer is PDU moisture indicator is pink. When the PDU moisture indicator is pink, it indicates that there is excessive moisture in the HUD PDU. This can be a cause for concern as excessive moisture can lead to damage and malfunction of the PDU. It is important to address this issue and take necessary steps to remove the moisture and prevent further damage.

The LANTIRN HUD would be the best option for using the HUD PDU with the largest FOV. LANTIRN stands for Low Altitude Navigation and Targeting Infrared for Night, and it is a system used by military aircraft for navigation and targeting. The LANTIRN HUD is specifically designed to provide a wide field of view, allowing pilots to have a broader visual coverage of their surroundings. This makes it ideal for situations where a larger field of view is required, such as in combat or low altitude flying.

The correct answer is "interruptive, meaning that normal operation of the subsystem is not available until the BIT has been completed." This means that during the actual Built-In Test (BIT), the normal operation of the subsystem is interrupted and not available until the BIT is completed.

During the process of boresighting the F-16 FCR, the boresight fixture is attached to the antenna. This is because the antenna plays a crucial role in the functioning of the FCR (Fire Control Radar) system. By attaching the boresight fixture to the antenna, the alignment and calibration of the radar system can be accurately adjusted. This ensures that the radar's line of sight is properly aligned with the aircraft's reference axis, allowing for precise targeting and tracking of objects.

The indication that the SDC has latched is that the radar altitude in the display is frozen, even though the aircraft altitude is changing. This suggests that the system has locked onto a specific altitude and is not updating the displayed value. This can be a useful indication for a pilot to know that the SDC has latched and they should be aware of the frozen altitude reading.

The size of the air-to-air missile allowable steering error circle depends on the missile type and selected field of view (FOV). The missile type determines the capabilities and specifications of the missile, including its accuracy and maneuverability. The selected FOV refers to the field of view that the missile's guidance system can cover. By considering both the missile type and selected FOV, the allowable steering error circle can be determined, which affects the missile's ability to hit its target accurately.

The UART (Universal Asynchronous Receiver/Transmitter) provides the communication link between all the CMFD (Centralized Multi-Function Display) and the CPDG (Centralized Processor and Display Generator). UART is a hardware component that allows serial communication between devices. It converts parallel data from the CMFD and CPDG into serial data for transmission and vice versa. This enables the exchange of information and data between the two components, facilitating their communication and coordination.

Depressing the LIST priority override key on the UFCs will cause the UFCs to display a list of infrequently accessed DED (Data Entry Display) pages. This means that the DED pages that are not frequently used or accessed will be shown on the UFCs for selection.

When altitude data is unavailable, the HUD displays the barometric altitude. This is because barometric altitude is calculated using atmospheric pressure, which can be measured by the aircraft's instruments. It provides an estimate of the aircraft's height above sea level based on the atmospheric pressure at that location. This information is important for pilots to maintain safe flying conditions and navigate accurately, especially when other altitude data sources are not accessible.

CARA R/T is the correct answer because it stands for "Controlled Approach Radar Altimeter/Receiver-Transmitter", which is a component in the F-16 that processes returned RF signals and provides radar altitude signals to other equipment. The CARA R/T is responsible for accurately measuring the altitude of the aircraft during controlled approach operations.

If DED or PFLD data is displayed on the HUD, it will prevent the roll indicator from being displayed. The DED (Data Entry Display) and PFLD (Pilot Fault List Display) are other types of information that can be shown on the HUD, and when they are being displayed, the roll indicator will not be visible.

The FCR TWS mode, which stands for Fire Control Radar Track While Scan mode, has the capability to track up to 10 targets. This mode allows the radar system to simultaneously track multiple targets while scanning the surrounding area for additional targets. With the ability to track 10 targets, the FCR TWS mode provides a comprehensive situational awareness, making it an effective tool in various applications such as military defense systems or air traffic control.

The correct answer is parallel intermodule/ serial digital test and maintenance bus. This bus provides communication between modules in a parallel and serial manner, allowing for testing and maintenance operations to be performed on the modules. It is specifically designed for carrying out diagnostic tests and maintenance tasks on the modules in a digital format.

The B-scan format is the correct answer because it refers to a type of radar display that shows a cross-sectional view of the radar returns. This format is commonly used in situations where the radar is scanning a specific area or target and needs to provide a detailed representation of the echoes received. The B-scan format is different from a PPI display, which shows a plan position indicator of the radar returns, and from a logarithmic display, which shows the radar returns on a logarithmic scale. A programmable PPI format refers to a customizable version of the PPI display.

To initiate the CARA IBIT, the correct action is to depress the OSB adjacent to RALT on the MFD TEST page. This means that the Integrated Bit Test (IBIT) for the CARA system is started by pressing the On-Screen Button (OSB) located next to the RALT (Radio Altimeter) option on the Multi-Function Display (MFD) TEST page.

During a CARA IBIT (Continuous Aircraft Recovery Aid - In-Built Test), the MFD (Multi-Function Display) will highlight the RALT (Radio Altimeter) indication and display the value of 300 feet beneath the mnemonic. This indicates that the IBIT is in progress and the RALT system is being tested. The highlighting of the RALT indication and the display of 300 feet is a visual feedback to the pilot that the test is ongoing.

The F-16C/D FCR LRU (Line Replaceable Unit) that generates the RF (Radio Frequency) drive signal to be amplified and transmitted is the MLPRF (Medium Power Radio Frequency) unit. The MLPRF unit is responsible for generating the necessary RF signal and transmitting it with amplification. It plays a crucial role in the functioning of the F-16C/D FCR system.

The correct answer is the 100mr circle below the boresight cross at 0 degrees azimuth and -3 degrees elevation. This means that the maximum toss anticipation cue is a circle with a radius of 100mr (mils of range) located below the boresight cross at a specific azimuth and elevation. This cue is used to help determine the appropriate range for a toss in a specific direction.

The correct answer is LANTIRN TGT pod, HUD, FCR. The LANTIRN TGT pod, HUD (Head-Up Display), and FCR (Fire Control Radar) are the F-16 systems that require boresighting in addition to the INS (Inertial Navigation System) and the gun. Boresighting is the process of aligning the sights or targeting systems of an aircraft to ensure accuracy and precision in weapon delivery. In this case, the LANTIRN TGT pod, HUD, and FCR need to be boresighted to ensure their proper functioning and effectiveness in combat situations.

When the designate switch is released to command the F-16C/D FCR system to enter single target track, the target will appear on the MFD as a triangle enclosed in a circle. This symbol is used to represent a tracked target on the display.

The F-16's JHMCS FOV refers to the field of view of the Joint Helmet Mounted Cueing System. This system allows the pilot to see and track targets outside the aircraft's cockpit by simply looking at them. The FOV determines the extent of the pilot's vision while using this system. In this case, the correct answer is 20 degrees, indicating that the pilot can see targets within a 20-degree angle from the center of their vision.

The optional clinometer is used to check and set angular relationships of parts to each other in the pitch or roll plane. This means that it can be used to measure and adjust the angles of parts in either the vertical (pitch) or horizontal (roll) planes. It is not limited to just one plane, but can be used in both.

In GMT mode on the FCR, fine MTG adjustments are made on the Throttle Gain Control. This means that when the aircraft is in GMT mode, the pilot can make small adjustments to the throttle gain control to fine-tune the aircraft's performance. The throttle gain control is responsible for regulating the sensitivity and responsiveness of the throttle inputs, allowing the pilot to have precise control over the engine power. By adjusting the throttle gain control, the pilot can optimize the aircraft's performance and ensure smooth and accurate throttle response.

The correct answer is 4. This suggests that there are a total of 4 HUD test pattern pages that can be selected with the TEST switch.

If the F-C/D FCR target aspect angle exceeds 60 degrees, the intercept steering symbol will blank. This means that the symbol will not be displayed on the screen. This could be because the angle is too large and the system is unable to accurately determine the position or direction of the target. Therefore, the symbol is not shown to avoid providing misleading information to the user.

The correct answer is C (L) MUX only. This means that the outputs from the Joint Helmet Mounted Cueing System (JHMCS) European Unit (EU) are only sent to the Mission Management Computer (MMC) over the C (L) MUX. This indicates that the JHMCS EU does not communicate with the MMC through any other MUX, such as C (R) MUX, A MUX, or B MUX.

In GMT1 mode, the F-16C/D radar transmitter operates in a low PRF with precision clutter tracking. This means that the radar transmitter uses a low Pulse Repetition Frequency (PRF) to accurately track and separate clutter from the target. This is important in order to maintain precision and accuracy in detecting and tracking targets while minimizing interference from clutter in the environment.

When the CNI page is displayed, there are three function values that can be changed using the increment/decrement switch.

The correct answer is the air-to-air missile range scale. This scale on the HUD is used to indicate the minimum and maximum range of air-to-air missiles. It consists of a vertical line that represents the range, with a smaller vertical line indicating the no-escape zone. This scale helps pilots determine the distance at which they can engage enemy aircraft with their missiles.

The FOV display on the F-16 FCR can be expanded while in GM mode by using either the pinky switch on the side stick controller or the FOV switch on the MFD.

The correct answer is PDU and the gun. A boresight confidence check is performed on LRUs (Line Replaceable Units) suspected to be out of tolerance. However, the PDU (Power Distribution Unit) and the gun are not included in this check. This suggests that the PDU and the gun are not relevant to the boresight alignment process or are not expected to cause any tolerance issues.

The A/A capabilities of the radar set used on any of the F-16 models include target detection and tracking. This means that the radar system is able to detect and track targets in the air. It can identify and monitor the movement of potential threats or targets of interest. This is an important capability for fighter jets like the F-16, as it allows the pilot to maintain situational awareness and engage with enemy aircraft effectively.

The correct answer is that the velocity switch in GND SPD, when the landing gear handle is lowered, automatically switches from ground track to magnetic heading. This means that when the landing gear is lowered during air-to-air mode, the display will switch from showing the aircraft's ground track to showing its magnetic heading. This is a useful feature as it allows the pilot to easily see the direction in which the aircraft is heading.

To determine an F-16's pitch angle deviation, you would use the pitch platform and clinometer. The pitch platform is a device that allows the measurement of the aircraft's pitch angle, which is the angle between the aircraft's longitudinal axis and the horizontal plane. The clinometer, also known as an inclinometer, is a tool used to measure the angle of inclination or slope. By using both the pitch platform and clinometer, the pilot or technician can accurately determine the pitch angle deviation of the F-16.

The F-16C/D systems that have the capability for electronic boresight are the HUD, camera, and the hard points (left and right) for LANTIRN, INS, FCR, and FLIR.

The correct answer is CU. The CU (Control Unit) contains the high-voltage power supply that is used to power the CRT (Cathode Ray Tube) in the JHMCS (Joint Helmet Mounted Cueing System) HDU (Helmet Display Unit). The CU is responsible for controlling and managing various functions of the JHMCS system, including providing power to the display unit.

There are five levels of EEGS.

The Doppler effect is a principle that allows the radar system to "lock on and track a target." This means that the radar system can accurately identify and follow a specific target, continuously updating its position and trajectory. The Doppler effect is used to measure the change in frequency of the radar waves reflected off the target, which provides information about its movement. By "locking on," the radar system focuses its attention on the target and maintains a continuous tracking of its location.

Level 2 declutter is being used in the F-16's JHMCS if altitude, range to steer point, and head heading scale are being decluttered. This level of declutter removes non-essential information and displays only the most important data for the pilot's situational awareness.

The HDU (Helmet Display Unit) is the JHMCS (Joint Helmet Mounted Cueing System) component that contains the MRU (Motion Reference Unit). The MRU is responsible for tracking the pilot's head movements and providing accurate information to the JHMCS system, allowing the pilot to effectively cue and engage targets.

The correct answer is that an R mnemonic is displayed along with the altitude scale. This means that there is a visual representation of the letter "R" along with the altitude scale on the HUD. This indication helps the pilot to easily identify the ALT switch on the HUD remote control panel.

When the JHMCS TD cockpit blanking is enabled and the HMCS LOS is in the cockpit blanking region, the target locator line will stay displayed. The target locator line is a symbology that helps the pilot locate and track targets. It provides a visual reference for the pilot to accurately aim at the target. Despite the cockpit blanking, the target locator line remains visible to assist the pilot in maintaining situational awareness and effectively engaging targets.
