A specialized Science and Technology quiz designed for UPSC CSE Prelims 2027 aspirants. Covers critical topics including Instrument Landing Systems (ILS), Indian space startups, and H1N1 influenza.

  • The Instrument Landing System (ILS) provides precise lateral and vertical guidance for aircraft landing.
  • Indian startups like Agnikul, Skyroot, and GalaxEye are leading the private space revolution.
  • H1N1 influenza is a respiratory viral illness caused by a subtype of the Influenza A virus.

For aspirants preparing for the UPSC CSE Prelims 2027, mastering Science and Technology is vital for success. This week's quiz (Week 177) focuses on high-yield topics that bridge the gap between static syllabus concepts and current technological advancements.

Understanding the Instrument Landing System (ILS)

The Instrument Landing System (ILS) is a cornerstone of modern aviation safety. It utilizes radio signals emitted from ground-based equipment to provide pilots with precise lateral and vertical guidance toward the runway. This is particularly critical during low-visibility operations such as heavy fog, thunderstorms, or intense precipitation.

In the Indian context, the Airports Authority of India (AAI) categorizes operations into CAT I, CAT II, and CAT III based on decision heights and Runway Visual Range (RVR). It is important to note that while ILS guides the aircraft, it does not monitor engine performance or fuel status—those tasks remain the responsibility of the aircraft's onboard diagnostic systems.

Why This Matters

BozokMedia analysis shows that UPSC frequently integrates aviation technology and infrastructure safety into its science and technology section. Understanding how global standards like ILS function is essential for tackling complex, application-based questions.

The integration of private players into the space sector is transforming India into a global magnet for scientific talent.

The Rise of India's Private Space Ecosystem

India has undergone a paradigm shift by opening its space sector to domestic private players. Prime Minister Narendra Modi has lauded the courage of space entrepreneurs, noting that they could attract a global talent pool to India's growing ecosystem.

AgnikulSpace Technology & Rocketry
SkyrootPrivate Launch Services
GalaxEyeAdvanced Satellite Imaging

With over 400 space startups currently active, companies like Agnikul, Skyroot, and GalaxEye are at the forefront of indigenous space technological development.

Did You Know?: Aircraft are engineered to be conductive, allowing lightning strikes to travel around the fuselage and exit safely without harming passengers.

Frequently Asked Questions

1. Does the ILS help in determining aircraft weight?
No, weight and balance are determined through specific loading procedures before the flight begins.

2. What is the significance of CAT III operations?
CAT III operations allow aircraft to land in much poorer visibility conditions compared to CAT I or II.
