Cordite is primarily a propellant, which falls under the category of low explosives or deflagrating explosives, not high explosives. High explosives detonate, while low explosives deflagrate (burn rapidly). TNT (Trinitrotoluene) and PETN (Pentaerythritol tetranitrate) are well-known high explosives used in military, industrial, and terrorist applications. PEK is not a commonly recognized acronym for an explosive substance, but based on the options, Cordite is definitively not a high explosive.
– **High Explosives:** Detonate rapidly, producing a powerful shock wave (e.g., TNT, PETN, RDX).
– **Low Explosives:** Deflagrate (burn rapidly), used as propellants (e.g., Cordite, black powder, smokeless powder).
– Cordite is a composite propellant made from nitrocellulose and nitroglycerine.
The distinction between high and low explosives is crucial in understanding their applications and safety handling procedures. High explosives are used for demolition and warheads, while low explosives are used to propel projectiles (in firearms and artillery) or as propellants in rockets.

A passenger who has checked in for a flight but does not present themselves for boarding at the gate before the flight departs is commonly referred to as a “no-show”. Specifically, in aviation terms, this is often categorized as a “Gate no-show”.
– **Gate no-show:** A passenger who has completed the check-in process but fails to arrive at the boarding gate by the specified time.
– Other terms like Cancelled passenger (B) implies they cancelled their reservation.
– Transit passenger (C) refers to a passenger passing through an airport en route to another destination.
– Deported passenger (D) refers to someone being removed from a country.
Airlines track no-shows as it impacts capacity management and potential revenue loss. Depending on the fare rules, airlines may penalize no-shows or cancel subsequent legs of their journey.

In aviation, the pilot designated as being in charge of the aircraft and having the ultimate responsibility for its operation and safety during flight is known as the Pilot in Command (PIC).
The Pilot in Command (PIC) is the specific term for the pilot with final authority and responsibility for the aircraft.
The Co-pilot assists the Pilot in Command, and while both are pilots, only one is designated as the PIC for any given flight. The term “Flight Commander” is more commonly used in military aviation or specific operational contexts, not standard civil aviation terminology for the pilot in charge.

The Airport Operator is the entity responsible for the overall management, operation, and security of the airport premises. This includes implementing and managing the access control system for the airport, ensuring that only authorized personnel and vehicles enter restricted areas. While security forces (APSU/ASG) enforce the access control, and BCAS sets the regulations, the ultimate responsibility for managing the airport’s security infrastructure and ensuring access control is implemented rests with the Airport Operator.
The Airport Operator holds the primary responsibility for the overall security management of the airport, including the implementation and maintenance of access control systems.
The Airport Security Unit (ASU) or Airport Security Group (ASG/APSU) personnel are responsible for physically enforcing the access control procedures established by the Airport Operator in accordance with BCAS regulations.

While certain authorized personnel like SPG or PSOs accompanying VVIPs may be permitted to carry weapons under specific security protocols, the Sky Marshal’s primary role and operational requirement is to be an armed officer ready for immediate action during a flight. They are specifically authorized to carry loaded weapons accessible for use in the aircraft cabin to counter potential threats.
Sky Marshals are specifically deployed as armed security personnel on flights and are authorized to carry loaded weapons for the purpose of in-flight intervention.
Authorization for other personnel (like SPG or PSOs) to carry weapons on flights often involves different procedures, potentially including checked baggage or specific securing methods, whereas the Sky Marshal’s weapon is kept readily accessible.

Sky Marshals, being authorized security personnel, need to identify themselves as such to other security staff, airline crew, etc. The primary document for this identification is their official Identity Card issued by their parent organization (e.g., NSG or CISF, if applicable). While weapon authorization is necessary for them to carry a weapon, the security personnel at the checkpoint would primarily verify their official status via their Identity Card.
The official Identity Card is the key document checked by security personnel to confirm the status of a Sky Marshal.
Sky Marshals operate under strict protocols, and their identity and mission details are kept confidential. However, coordination with airport security requires proof of their official capacity.

Articles seized during the security screening of airline passengers are initially taken into custody by the security personnel who conduct the search. In India, this task is performed by the Airport Security Unit (ASU) or Airport Security Group (ASG), which are typically units of the CISF or State Police. These personnel are responsible for the handling, documentation, and disposal of seized items according to the procedures laid down by BCAS.
The Airport Security Unit (ASU) or Airport Security Group (ASG/APSU), comprising personnel from forces like CISF, are responsible for seizing and subsequently handling/disposing of prohibited articles found during passenger screening.
The disposal procedures vary depending on the nature of the item (e.g., legally prohibited weapons are handed over to police, liquids over limits might be discarded, less dangerous items may be returned or stored for collection).

In India, the Bureau of Civil Aviation Security (BCAS) is the regulatory authority for civil aviation security. While the Sky Marshals themselves are personnel from agencies like the NSG, their deployment schedule, including which flights are covered, is determined by the BCAS based on threat assessments and security requirements.
BCAS is the regulatory body that decides the deployment schedule and requirements for Sky Marshals on flights in India.
The actual Sky Marshals operating in India are typically commandos from the National Security Guard (NSG). The specifics of their deployment are classified for security reasons.

Common crime scene search methods include the Spiral method, Strip or Line method, Grid or Crisscross method, Zone method, and sometimes the Wheel or Ray method. However, the Wheel method (B) is often considered less systematic or effective for thorough coverage compared to the Spiral, Strip, or Grid methods, especially in large areas. While it is sometimes listed as a potential method for radiating outwards from a central point, it is less universally applied or recommended for comprehensive searches than the others listed.
While Spiral, Strip, and Crisscross (Grid) are standard and widely used crime scene search methods, the Wheel (Ray) method is less common and potentially less effective for ensuring complete coverage, leading it sometimes not to be listed as a primary method.
Each search method has its advantages and disadvantages depending on the size and type of the crime scene, the number of personnel available, and the nature of the expected evidence.
