DGCA fined for Tail strikes
GS Paper - 2 (Infrastructure)
The Directorate General of Civil Aviation (DGCA) has fined IndiGo a sum of Rs 30 lakhs and issued a show cause notice to the airline, following a special audit concerning frequent tail strike incidents. The special audit uncovered “certain systemic deficiencies” in IndiGo’s documentation pertaining to “operations/training procedures and engineering procedures”.
What is a tail strike?
A tail strike refers to an incident where the tail of an aircraft hits the ground or strikes any other stationary object.
While tail strikes can occur during takeoff, a majority happen during the landing of an aircraft.
According to Airbus statistical data, over 65 per cent of tail strikes happen during landings.
Tail strikes can cause significant damage to the aircraft, with major repairs needed to restore the plane’s structural integrity.
Even in cases where the damage is not major or immediately obvious, thorough inspections are carried out before the aircraft is declared fit to fly again.
What causes tail strikes?
While modern aircraft are fitted with a whole gamut of systems to aid pilots in flying aircraft and reduce the probability of human error, most tail strikes can be attributed to mistakes made by pilots.
Simply put, tail strikes occur when the pitch attitude of the aircraft (more on that in a moment) – while taking off or landing – is steep enough for the tail of the craft to hit the ground.
Aircraft, depending on their size, have different “tail strike margins” – the longer the aircraft, more prone it is to a tail strike as the rear of the plane juts out further behind the rear undercarriage.
An aircraft in flight is free to rotate in three dimensions: yaw, nose left or right about an axis running up and down; roll, rotation about an axis running from nose to tail; and pitch, nose up or down about an axis running from wing to wing. These are collectively known as an aircraft’s attitude.
Tail strikes are most impacted by the aircraft’s pitching motion. A positive pitching motion raises the nose of the aircraft and lowers the tail.
Tail strikes are caused by such a motion being executed improperly during take off and landing.

Satellite bus technology transfer to private firm
GS Paper- 3 (Space Technology)
ISRO said it has transferred the IMS-1 Satellite Bus Technology to Alpha Design Technologies Pvt. Ltd in a step towards enhancing private industry participation in the country's space sector. NewSpace India Limited (NSIL), the commercial arm of ISRO, facilitated the technology transfer through an agreement signed during an event held at the NSIL headquarters 2, the space agency said.
More about the News
The technology transfer documents were formally handed over by D Radhakrishnan, Chairman and Managing Director of NSIL to Col. H S Shankar (Retd.), Chairman and Managing Director of ADTL.
ADTL is one of the two private players identified to receive the transfer of this technology through Interest Exploratory Note (IEN) published by NSIL.
This transfer marks the beginning of satellite bus technologies developed by ISRO being transferred to private industries. Further, the PSLV is under productionisation by a consortium of industries.
ISRO has been enabling private players to develop space technologies by facilitating and extending the expertise thus ensuring both out-bound and in-bound approaches.
By transferring the IMS-1 technology to the private sector, ISRO/DoS (Department of Space) aims to bolster India's industrial growth in the space sector and foster technological self-reliance, it further said, adding the development opens up new avenues for private players to contribute to space research and exploration, in line with India's vision to expand its presence in the global space market.
About Satellite bus
The satellite bus, developed by ISRO's U R Rao Satellite Centre (URSC), is a versatile and efficient small satellite platform designed to facilitate low-cost access to space.
The bus serves as a dedicated vehicle for various payloads, enabling earth imaging, ocean and atmospheric studies, microwave remote sensing, and space science missions while ensuring a quick turnaround time for satellite launches.
The IMS-1 bus, weighing about 100 kg, accommodates a 30kg payload. Solar arrays generate 330W power with a raw bus voltage of 30-42 V, ISRO said, adding it offers a 3-axis stabilised with four reaction wheels with a 1 Newton thruster that provides +/- 0.1 degree pointing accuracy.
It is a forerunner for IMS-2 bus technology, capable of improved features, and IMS-1 bus is utilised in previous ISRO missions like IMS-1, Youthsat and Microsat-2D.
About ADTL
Alpha Design Technologies Pvt. Ltd (ADTL) is an aerospace and defence company, with expertise in engineering, manufacturing, and system integration.
It has been a key player in various projects related to defence, space and homeland security, contributing significantly to India's technological progress in these domains.
