The correct answer is D. According to aviation security regulations, passengers with prosthetics are not exempted from security screening.
All passengers are subject to security screening. For passengers with medical implants or prosthetics, modified screening procedures are followed to ensure both security and the dignity/comfort of the passenger. This might involve a combination of walk-through metal detectors, hand-held metal detectors, pat-down searches, and visual inspection, potentially in a private screening area. Exemption is not provided.
The specific procedures are designed to address the potential for metallic components in prosthetics triggering alarms while still ensuring that no prohibited items are concealed. Screening is mandatory regardless of medical condition or alert level.

The correct answer is B. The Bureau of Civil Aviation Security (BCAS), India’s aviation security regulator, primarily mandates the use of Millimeter-wave (MMW) technology for full body scanners at airports.
BCAS has issued guidelines specifying MMW technology as the standard for body scanners. This technology uses non-ionizing electromagnetic radiation, which is considered safe for passenger screening.
While Back Scatter Technology exists and uses ionizing radiation (X-rays), it is generally not preferred for widespread passenger screening in India due to potential health concerns and is often not the technology prescribed by BCAS for new installations compared to MMW technology. Therefore, only MMW is the technology prescribed for mandatory installation.

Airports in India are classified by the Bureau of Civil Aviation Security (BCAS) into categories such as Normal, Sensitive, and Hypersensitive based on threat perception, traffic volume, and other security considerations. Chennai airport (D) is a major international airport and is consistently classified as Hypersensitive. Pune airport (A) and Chandigarh airport (C) are generally classified as Sensitive airports. Jaipur airport (B), while a significant airport and tourist destination, is also commonly classified as a Sensitive airport. Based on common classifications where Chennai is Hypersensitive and Pune, Jaipur, and Chandigarh are Sensitive, any of the options A, B, or C would technically be correct answers to the question “Which one of the following is not a hypersensitive airport?”. However, assuming the question intends a single correct answer from the given options based on a specific official classification list used by the exam setters, and acknowledging the potential for variation in classification lists over time or by specific criteria, Jaipur airport (B) is selected as the intended answer, implying it is classified as Sensitive while potentially other options listed under A and C might be considered Hypersensitive in that specific context, along with D.
Airport classification (Normal, Sensitive, Hypersensitive) is crucial for determining the level of security measures required. Chennai is a Hypersensitive airport. Pune, Jaipur, and Chandigarh are generally classified as Sensitive.
The exact list of airports in each category can change based on dynamic threat assessments. While Chennai is consistently listed as Hypersensitive, the classification of other airports like Pune, Jaipur, and Chandigarh as Sensitive or potentially Hypersensitive can sometimes vary depending on the source and date of classification. The question, as phrased with the provided options, contains ambiguity if interpreted using commonly available classification lists where multiple options are Sensitive (and thus not Hypersensitive).

LAGs is an acronym used in aviation security that stands for Liquids, Aerosols, and Gels. Following security incidents involving liquid explosives, regulations were introduced globally (and implemented by bodies like BCAS in India) restricting the quantity of liquids, aerosols, and gels that passengers can carry in their hand baggage.
LAGs refer to the category of substances (Liquids, Aerosols, Gels) that are subject to specific restrictions in hand baggage on aircraft.
Typical regulations limit individual LAGs containers to 100 ml (or equivalent) and require them to be placed in a single transparent, resealable plastic bag with a maximum capacity of 1 litre per passenger.

The Central Industrial Security Force (CISF) is unique among the Central Armed Police Forces (CAPFs) in that it is primarily a cost-reimbursement force. While other CAPFs (like BSF, CRPF, ITBP, SSB) are primarily deployed for border guarding or internal security duties with costs covered by the central government, CISF provides security cover to public sector undertakings, industrial units, government buildings, airports, ports, power plants, etc., and the cost of this deployment is reimbursed by the entity receiving the security cover to the government.
The cost-reimbursement model for its deployments is a distinctive feature of the CISF compared to other CAPFs.
Other CAPFs also have armed capabilities (making A incorrect), and while intelligence gathering and disaster management are functions they contribute to (often through deputation to agencies like NDRF or having their own intelligence wings), CISF is not the *only* force performing these roles (making B and C incorrect as unique features).

A Mini Remotely Operated Vehicle (MROV) equipped for EOD and surveillance is designed to operate in various environments, including confined spaces and public areas, to investigate suspicious objects or conduct reconnaissance without risking human life. In an airport environment, suspicious items or potential threats could be located inside aircraft cabins, lavatories, or cargo holds (1), within the public areas of passenger terminals (2), or in other buildings, offices, or cargo facilities within the airport complex (3). A versatile MROV would be capable of navigating and conducting operations in all these locations.
MROVs are versatile tools used in EOD and surveillance across diverse environments, including those found within an airport.
MROVs used in security or EOD contexts are typically equipped with cameras, manipulators (arms) for interacting with objects, and sometimes other sensors like chemical detectors or disruptors. Their size and maneuverability make them suitable for accessing areas that may be dangerous or difficult for human personnel.

Technical specifications for security equipment like NLJDs, particularly in regulated environments like airports or security forces, often prescribe minimum performance standards. While the exact standard referenced here requires specific documentation (likely from BCAS or procurement guidelines), detecting electronic components like ABCD circuits (possibly referring to standard electronic logic circuits used in timers or triggers) buried under dry soil is a typical application for NLJDs in search operations. A depth of at least 12 inches (approximately 30 cm) is a plausible minimum requirement for such detection capabilities in certain operational contexts. Without access to the specific official specification, it is difficult to confirm definitively, but 12 inches fits within the expected performance range for such equipment detecting small buried targets.
NLJDs are used for detecting buried or concealed electronic components. Performance specifications include detection depth.
The effective detection depth of an NLJD depends on various factors, including the power of the transmitter, the sensitivity of the receiver, the size and orientation of the target non-linear junction, and the composition and moisture content of the medium (soil, walls, etc.) it is searching through. Dry soil generally allows for better penetration compared to wet or highly conductive soil.

A Non-Linear Junction Detector (NLJD) is a device used to detect electronic components. It operates by transmitting a low-frequency signal and listening for harmonic responses characteristic of non-linear junctions found in semiconductors (diodes, transistors, integrated circuits). This allows it to locate electronic devices, such as listening devices, cameras, GPS trackers, or electronic components within an Improvised Explosive Device (IED), even if they are switched off.
NLJDs detect devices containing semiconductors, which are fundamental components of electronic circuits.
NLJDs are primarily used in technical surveillance counter-measures (TSCM) and Explosive Ordnance Disposal (EOD) or search operations to find hidden electronic devices or components of IEDs. They do not directly detect explosive materials themselves, but rather the electronic triggering or control components.
