  • [pib] ABHYAS Air Vehicle

    Successful flight test of ABHYAS – High-speed Expendable Aerial Target (HEAT) was today conducted by Defence Research and Development Organisation (DRDO) from the Interim Test Range, Balasore in Odisha.

    (b) India’s indigenous anti-missile programme

    (c) An American anti-missile system

    (d) A defence collaboration between Japan and South Korea

    ABHYAS Air Vehicle

    • ABHYAS is designed & developed by Aeronautical Development Establishment (ADE), DRDO.
    • The air vehicle is launched using twin underslung booster.
    • It is powered by a small gas turbine engine and has a MEMS-based Inertial Navigation System (INS) for navigation along with the Flight Control Computer (FCC) for guidance and control.
    • The vehicle is programmed for fully autonomous flight. The check out of air vehicle is done using laptop-based Ground Control Station (GCS).
    • During the test campaign, the user requirement of 5 km flying altitude, vehicle speed of 0.5 mach, the endurance of 30 minutes and 2g turn capability of the test vehicle were successfully achieved.

    Its uses

    • Abhyas’s radar cross-section (RCS), as well as its visual and infrared signatures, can be augmented to simulate a variety of aircraft for air-defence weapon practices.
    • It can also function as a jammer platform and decoy.
    • The HEAT system is utilized to do away with the post-launch recovery mode, which is time-consuming and difficult in a scenario as the sea.

  • What are Medicanes?

    Very recently, a medicane named Ianos made landfall along the coast of Greece and caused heavy rainfall and flooding on the islands of Zakynthos, Kefalonia and Ithaca.

    What are Medicanes?

    • Medicanes are extra-tropical hurricanes observed over the Mediterranean Sea.
    • Medicanes occur more in colder waters than tropical cyclones, hurricanes and typhoons.
    • Hence, the cores of these storms are also cold, as compared to the warm cores of tropical cyclones.
    • Warmer cores tend to carry more moisture (hence rainfall), are bigger in size and have swifter winds.
    • The main societal hazard posed by Medicanes is not usually from destructive winds but through life-threatening torrential rains and flash floods.

    Why in news?

    • This year is a mild La Niña, according to the World Meteorological Organization.
    • La Niña is the cooling phase of the El Niño Southern Oscillation (ENSO) cycle in the equatorial Pacific Ocean, as opposed to the warming El Niño phase.
    • It is characterized by the unusual cooling of the central and east-central equatorial Pacific Ocean.
    • A La Niña produces more rain in the central-eastern part, where most of the Mediterranean cyclones develop.

    Mt. Everest

    • Mount Everest or Sagarmatha, Earth’s highest mountain above sea level, is located in the Himalayas between China and Nepal -– the border between them running across its summit point.
    • Its current official elevation – 8,848m – places it more than 200m above the world’s second-highest mountain, K2, which is 8,611m tall and located in Pakistan-occupied Kashmir.
    • The mountain gets its English name from Sir George Everest, a colonial-era geographer who served as the Surveyor General of India in the mid-19th century.
    • Considered an elite climbing destination, Everest was first scaled in 1953 by the Indian-Nepalese Tenzing Norgay and New Zealander Edmund Hillary.

    Everest’s first survey

    • The mission to measure the world’s highest peak was taken up on a serious note in 1847 and culminated with the finding of a team led by Andrew Waugh of the Royal Surveyor General of India.
    • The team discovered that ‘Peak 15’ — as Mt Everest was referred to then — was the highest mountain, contrary to the then-prevailing belief that Mt Kanchenjunga (8,582 m) was the highest peak in the world.
    • Another belief, prevailing even today, is that 8,840 m is not the height that was actually determined by the 19th-century team.
    • That survey, based on trigonometric calculations, is known as the Great Trigonometric Survey of India.

    Why is the height being measured again?

    • Everest’s current official height– 8,848m– has been widely accepted since 1956, when the figure was measured by the Survey of India.
    • The height of the summit, however, is known to change because of tectonic activity, such as the 2015 Nepal earthquake.
    • Its measurement over the decades has also depended on who was surveying.
    • Another debate is whether the height should be based on the highest rock point or the highest snow point.

  • What are Interest Rate Derivatives (IRDs)?

    (c) Promissory Note

    (d) Participatory Note

    Interest Rate Derivatives (IRDs)

    • An IDR is a financial instrument with a value that is linked to the movements of an interest rate or rates.
    • These may include futures, options, or swaps contracts.
    • They are often used by institutional investors, banks, companies, and individuals to protect themselves against changes in market interest rates.
    • The proposed directions by RBI are aimed at encouraging higher non-resident participation, enhance the role of domestic market makers in the offshore market, improve transparency, and achieve better regulatory oversight, according to the central bank.

    Back2Basics: Foreign portfolio investment (FPI)

    • FPI involves holding financial assets from a country outside of the investor’s own.
    • FPI holdings can include stocks, ADRs, GDRs, bonds, mutual funds, and exchange-traded funds.
    • Along with foreign direct investment (FDI), FPI is one of the common ways for investors to participate in an overseas economy, especially retail investors.
    • Unlike FDI, FPI consists of passive ownership; investors have no control over ventures or direct ownership of property or a stake in a company.

    FPI vs FDI

    • With FPI—as with portfolio investment in general—an investor does not actively manage the investments or the companies that issue the investments.
    • They do not have direct control over the assets or the businesses.
    • In contrast, foreign direct investment (FDI) lets an investor purchase a direct business interest in a foreign country.
