GS III – Economy and Infrastructure

Civil Aviation, Regional Connectivity and Inclusive Development

Introduction

Launched in 2016 under the National Civil Aviation Policy, UDAN (Ude Desh ka Aam Nagrik) seeks to make air travel affordable and connect underserved regions. As the scheme completes a decade in 2026, its next phase highlights a critical challenge: transforming subsidised regional connectivity into a financially sustainable system that promotes economic integration, social inclusion and balanced regional development.

Background and policy framework

• Objective: Improve affordable air connectivity to underserved and unserved regions through capped fares and Viability Gap Funding (VGF).
• Institutional framework: Ministry of Civil Aviation, Airports Authority of India (AAI), airlines and State/UT governments.
• Modified UDAN: Launched in July 2026, with an outlay of ₹28,840 crore for FY 2026–27 to FY 2035–36. It focuses on airport development, operational sustainability and indigenous aviation capacity. 

Multidimensional significance

• Economic: Promotes tourism, trade, investment and regional employment.
• Social: Improves access to healthcare, education and emergency services.
• Strategic: Strengthens connectivity in border, northeastern and remote regions.
• Agricultural: Enables faster movement of high-value and perishable products.

Examples: Deoghar supports pilgrimage tourism and access to healthcare; Tezu improves connectivity in Arunachal Pradesh; Kishangarh facilitates marble trade and tourism. 

Modified UDAN: Key provisions

The Challenge Mode Portal enables States and UTs to nominate suitable airstrips and helipads. Tapered subsidies seek to encourage routes to become commercially viable over time. 

Key challenges

• Financial viability: Low passenger demand, high operating costs and seasonal traffic can make regional routes dependent on subsidies.
• Infrastructure gaps: Airport construction does not guarantee regular flights, adequate maintenance or reliable all-weather operations.
• Regional inequality: Airlines may prioritise profitable destinations over remote communities with greater social needs.
• Last-mile connectivity: Poor road links and limited public transport reduce airport accessibility.
• Environmental concerns: Airport expansion and aviation emissions require appropriate ecological safeguards.
• Administrative coordination: Delays in land, utilities and intergovernmental coordination can undermine implementation.

Critical analysis

UDAN demonstrates the value of state intervention in correcting market failures where social benefits exceed immediate commercial returns. However, three distinctions are crucial:

• Airport creation is not connectivity: Infrastructure must support reliable, regular services.
• Connectivity is not inclusion: Affordability and equitable regional distribution determine who benefits.
• Subsidisation is not sustainability: Routes need stronger demand and transparent performance evaluation.

Articles 38 and 39(b) provide broader constitutional principles of social justice and the common good, although neither specifically mandates regional aviation. International regional-air-service models offer useful lessons in competitive route allocation, time-bound subsidies and performance-linked funding.

Way forward

1. Outcome-based subsidies: Link VGF to flight regularity, passenger utilisation and affordability.
2. Economic integration: Connect airports with tourism circuits, industrial clusters, agricultural markets and medical hubs.
3. Cooperative federalism: Involve States in route planning, feeder transport and infrastructure maintenance.
4. Indigenous capacity: Strengthen domestic aircraft manufacturing, maintenance, repair and overhaul (MRO), and aviation training.
5. Green aviation: Promote renewable-powered airports, energy efficiency and ecological safeguards.
6. Accountability: Publish route-wise passenger, subsidy and cancellation data and conduct independent cost-benefit assessments.

Conclusion

UDAN has demonstrated that aviation can promote regional integration beyond metropolitan centres. Its long-term success depends on moving from infrastructure expansion to reliable, affordable and sustainable services. Transparent subsidies, stronger State participation, indigenous capabilities and environmental safeguards can transform regional aviation into an instrument of inclusive development, constitutional justice and India’s broader Viksit Bharat vision.

UPSC Mains practice question

1. Regional aviation is an instrument of inclusive growth rather than merely a transport-sector intervention. Critically examine the achievements and limitations of the UDAN scheme and suggest measures to ensure its long-term sustainability. (15 marks, 250 words)

GS II – Governance / GS III – Science & Technology
Education, Artificial Intelligence, and Assessment Reform

Introduction

The growing concern among academics is that students are using artificial intelligence (AI) tools to write assignments and even research papers. Their immediate reaction is to blame the technology. But perhaps one should pause and ask a different question: what exactly are we asking students to do? For much of our teaching careers, students have worked towards examinations and assignments with one clear objective: getting the right answer. Schools and universities have largely rewarded the final product—not the effort that went into reaching it. A student who memorises an answer the night before can score as well as one who spent weeks understanding the subject. AI has made the shortcut much easier—and exposed the limitations of a system that rewards answers, completion, and conformity over understanding.

The Problem: Rewarding the Product, Not the Process

The Existing System

• Objective: Getting the right answer.
• Reward: Final product; marks for what appears on the answer sheet.
• Outcome: Memorisation scores as well as deep understanding.

AI Makes Shortcuts Easier

• Temptation: If a machine can produce expected output in seconds, some students will use it.
• Not Laziness Alone: We have trained students for years to produce what is expected, meet deadlines, and move on.

The Coaching Culture

• Exam Preparation: Students spend countless hours learning to recognise question patterns for Board exams, JEE, and NEET.
• Weakness: Some may find it difficult to explain a basic concept in their own words.
• Key Point: AI did not create this habit—it entered a system where the habit already existed.

The Reframing: Question the Task, Not the Student

What Was the Student Expected to Learn?

• Easy Tasks: Summarising a chapter or explaining a familiar concept—a chatbot can do this well.
• If the Task Requires Little Independent Thought: Question the task before questioning the student.

Assessment Redesign

• Follow-Up Conversations: Ask why a particular argument was chosen; how an idea applies to a different situation.
• In-Class Explanations: Ask students to explain the answer in class.
• Outcome: Tells us much more about whether the student has understood the subject.

Practical Difficulty

• Large Classes, Heavy Workloads: More meaningful assessment takes more time.
• Institutional Support: Cannot ask teachers to do more without asking if institutions will provide support.

The Positive Side of AI

Expanding Access

• For Students Without: Private tutors, good libraries, or academic help at home.
• AI Can Provide: Explanations and feedback once difficult to obtain.

The Opportunity

• Reconsider Old Assumptions: Examinations that reward answers; assignments that reward completion; classrooms that leave little space for individual thinking.
• AI Has Exposed: The limitations of this system.

Way Forward

Redesign Assessment

• Beyond the Final Product: Assess understanding, not just output.
• Conversations and Explanations: Oral examinations; follow-up interviews; in-class presentations.
• Process Portfolios: Track drafts, revisions, and reflections.

Build Institutional Capacity

• Reduce Class Sizes: Where possible; provide teaching assistants.
• Teacher Training: In assessment design and AI-integrated pedagogy.
• Time and Resources: For meaningful assessment.

Embrace AI as a Tool

• For Students: Access to explanations and feedback.
• For Teachers: Assist with routine tasks; free time for meaningful interaction.
• Guidelines: Clear policies on AI use; academic integrity.

The Larger Question

• Not Whether Students Should Use AI: But whether our assessments are designed to find out what students have understood—or simply what they can produce.
• That May Be the More Important Examination Teachers Need to Take.

Conclusion

The growing concern about students using AI to write assignments is understandable—but the immediate reaction to blame technology misses the larger question. For years, our education system has rewarded the final product, not the process; memorisation, not understanding. AI has simply made shortcuts easier in a system where shortcuts already worked. The more useful question is why some assignments are so easy for AI. Assessment redesign—follow-up conversations, in-class explanations, process portfolios—can tell us much more about whether students have understood. But meaningful assessment takes time, and institutions must provide support. AI also has a positive side—expanding access for students without tutors or libraries. The right approach is to view AI as an opportunity to reconsider old assumptions about education. The question before us is larger than whether students should use AI. It is whether our assessments are designed to find out what students have understood—or simply what they can produce.

Practice Question

1. AI has exposed the limitations of an education system that rewards answers and completion over understanding; the right approach is to reconsider old assumptions about assessment. Critically examine the challenges and opportunities of AI in education and suggest reforms for meaningful assessment. (250 words, 15 marks)
