New Delhi, Oct 15: From being the people's President to spearheading the development of the most significant Indian missiles, late President Dr APJ Abdul Kalam has contributed to the development of the country in different spheres.

As an aerospace scientist, Kalam worked with India's two major space research organisations - Defence Research and Development Organisation (DRDO) and Indian Space Research Organisation (ISRO).

While, his work in the development and operationalisation of Indigenous guided missiles - AGNI and PRITHVI - earned him the title of the 'Missile Man of India,' there are many more ways in which Kalam has helped India in the division of science and technology.

On the 89th birth anniversary of Dr APJ Abdul Kalam, here are 5 of his scientific contributions to the country: -

1. Directed the project to develop India's first Satellite Launch Vehicle (SLV)

Back in 1980s, when India had hardly dreamt of having its indigenous Satellite Launch Vehicle (SLV), Dr Kalam's over 10-year-long hard work as the project director for the development of the indigenous Satellite Launch Vehicle at ISRO led to the ground-breaking scientific development.

It was in July 1980, that India's SLV-III successfully deployed the Rohini satellite in the near-Earth orbit leading to the country becoming a member of the exclusive Space Club.

2. Directed projects for the development of ballistic missiles

Kalam also headed the projects Devil and Valiant which had the aim of developing ballistic missiles using the technology behind the successful SLV program. Under mission Kalam with other projects, members developed many missiles including AGNI which is an intermediate-range ballistic missile and PRITHVI which is a surface-to-surface missile.

3. Headed multiple nuclear tests at Pokhran

Serving as the Chief Scientific Adviser to the then Prime Minister, Kalam played a major role in heading the Pokhran-II nuclear testing leading to him being known as the best nuclear scientist of the country at that time. The nuclear testing under the supervision of Kalam during the period of July 1992 to December 1999 made India a nuclear-armed state.

4. He worked in making healthcare accessible to all

Working jointly with cardiologist Soma Raju, the late President developed a cost-effective coronary stent 'Kalam-Raju Stent' which helped in making healthcare accessible to all.

5. Developed the rugged 'Kalam-Raju tablet'

The duo of Kalam and Soma Raju later in 2012 designed a rugged tablet computer for better health care administration in the rural pockets of the country. They termed it the 'Kalam-Raju tablet.'

For his work in the stream of science and politics, the 11th President was also awarded India's highest civilian honour or the Bharat Ratna.

Kalam breathed his last on July 27, 2015, while delivering a lecture at the Indian Institute of Management Shillong when he collapsed and died from a cardiac arrest.

Five years after his demise, his contributions are still remembered as some of the best scientific and technological developments in the country.

New Delhi: IndiGo, India’s largest airline, faced major operational turbulence this week after failing to prepare for new pilot-fatigue regulations issued by the Directorate General of Civil Aviation (DGCA). The stricter rules—designed to improve flight safety—took effect in phases through 2024, with the latest implementation on November 1. IndiGo has acknowledged that inadequate roster planning led to widespread cancellations and delays.

Below are the key DGCA rules that affected IndiGo’s operations:

1. Longer Mandatory Weekly Rest

Weekly rest for pilots has been increased from 36 hours to 48 hours.

The government says the extended break is essential to curb cumulative fatigue. This rule remains in force despite the current crisis.

2. Cap on Night Landings

Pilots can now perform only two night landings per week—a steep reduction from the earlier limit of six.

Night hours, defined as midnight to early morning, are considered the least alert period for pilots.

Given the disruptions, this rule has been temporarily relaxed for IndiGo until February 10.

3. Reduced Maximum Night Flight Duty

Flight duty that stretches into the night is now capped at 10 hours.

This measure has also been kept on hold for IndiGo until February 10 to stabilize operations.

4. Weekly Rest Cannot Be Replaced With Personal Leave

Airlines can no longer count a pilot’s personal leave as part of the mandatory 48-hour rest.

Pilots say this closes a loophole that previously reduced actual rest time.

Currently, all airlines are exempt from this rule to normalise travel.

5. Mandatory Fatigue Monitoring

Airlines must submit quarterly fatigue reports along with corrective actions to DGCA.

This system aims to create a transparent fatigue-tracking framework across the industry.

The DGCA has stressed that these rules were crafted to strengthen flight safety and align India with global fatigue-management standards. The temporary relaxations are expected to remain until February 2025, giving IndiGo time to stabilise its schedules and restore normal air travel.

IndiGo, India’s largest airline, is battling one of its worst operational disruptions in recent years, with hundreds of delays and cancellations throwing domestic travel into chaos.

Government data on Tuesday showed its on-time performance plunging to 35%, an unusual dip for a carrier long associated with punctuality.

By Wednesday afternoon, airports in Delhi, Mumbai, Bengaluru and Hyderabad had collectively reported close to 200 cancellations, stranding travellers across the country.

Crew Shortage After New Duty Norms

A major trigger behind the meltdown is a severe crew shortage, especially among pilots, following the rollout of revised Flight Duty Time Limitation (FDTL) norms last month.

The rules mandate longer rest hours and more humane rosters — a shift IndiGo has struggled to incorporate across its vast network.

Sources said several flights were grounded due to lack of cabin crew, while some delays stretched upwards of eight hours.

With IndiGo controlling over 60% of India’s domestic aviation market, the ripple effect has impacted airports nationwide.

IndiGo Issues Apology, Lists “Compounding Factors”

In a statement, IndiGo acknowledged the large-scale disruption:

“We sincerely apologise to customers. A series of unforeseen operational challenges — technology glitches, winter schedule changes, adverse weather, system congestion and updated FDTL norms — created a compounding impact that could not have been anticipated.”

To stabilise operations, the airline has begun calibrated schedule adjustments for the next 48 hours, aiming to restore punctuality. Affected passengers are being offered refunds or alternate travel arrangements, IndiGo said.

What the FDTL Rules Require

The FDTL norms, designed to reduce pilot fatigue, cap duty and flying hours as follows:
•    Maximum 8 hours of flying per day
•    35 hours per week
•    125 hours per month
•    1,000 hours per year

Crew must also receive rest equalling twice the flight duration, with a minimum 10-hour rest period in any 24-hour window.

The DGCA introduced these limits to enhance flight safety.

Hyderabad: 33 Flights Cancelled, Long Queues Reported

Hyderabad’s Rajiv Gandhi International Airport saw heavy early-morning crowds as 33 IndiGo flights (arrivals and departures) were cancelled.

The airport clarified on X that operations were normal, advising passengers to contact IndiGo directly for latest flight status.

Cancellations included flights to and from Visakhapatnam, Goa, Ahmedabad, Delhi, Bengaluru, Chennai, Madurai, Hubli, Bhopal and Bhubaneswar.

Bengaluru: 42 Flights Disrupted

Bengaluru’s Kempegowda International Airport recorded 42 cancellations — 22 arrivals and 20 departures — affecting routes to Delhi, Mumbai, Chennai, Hyderabad, Goa, Kolkata and Lucknow.

Passengers Vent on Social Media

Irate travellers took to X to share their experiences. One passenger stranded in Hyderabad wrote: “I have been here since 3 a.m. and missed an important meeting.”

Another said: “My flight was pushed from 1:55 PM to 2:55 PM and now 4:35 PM. I was informed only three minutes before entering the airport.”

Delhi Airport Hit by Tech Glitch

At Delhi Airport, the disruption deepened due to a slowdown in the Amadeus system — used for reservations, check-ins and departure control.

The technical issue led to longer queues and sluggish processing, adding to delays already worsened by staff shortages.

Mangaluru, Nov 28: Karnataka Health Minister and Dakshina Kannada district in-charge minister Dinesh Gundu Rao on Friday handed over Chief Minister Siddaramaiah’s letter to Prime Minister Narendra Modi, highlighting the severe distress faced by farmers due to crashing crop prices.

PM Modi arrived at the Mangaluru International Airport en route to Udupi, where Gundu Rao welcomed him and submitted the letter. The chief minister’s message stressed that farmers are suffering heavy losses because maize and green gram are being bought far below the Minimum Support Price (MSP). The state urged the Centre to immediately begin procurement at MSP.

According to the letter, Karnataka has a bumper harvest this year—over 54.74 lakh metric tons of maize and 1.98 lakh metric tons of green gram—yet farmers are unable to secure fair prices. Against the MSP of ₹2,400/MT for maize and ₹8,768/MT for green gram, market rates have plunged to ₹1,600–₹1,800 and ₹5,400 respectively.

The chief minister has requested the Centre to:

• Direct NAFED, FCI and NCCF to start MSP procurement immediately.
• Ensure ethanol units purchase maize directly from farmers or FPOs.
• Increase Karnataka’s ethanol allocation, citing high production capacity.
• Stop maize imports, which have depressed domestic prices.
• Relax quality norms for green gram, allowing up to 10% discoloration due to rains.

The letter stresses that MSP is crucial for farmer dignity and income stability and calls for swift central intervention to prevent a deepening crisis.
