सारांश
Airbus has issued a mandatory directive for software upgrades on its A320 family aircraft, including the A320, A321, and A319 models. This comes after a significant software glitch was identified in the elevator aileron computers, which are crucial for flight control. The issue, which has been under investigation since 2020, led to a temporary loss of control for a few seconds during certain flight conditions, affecting thousands of flights globally.
The European Union Aviation Safety Agency (EASA) and India's Directorate General of Civil Aviation (DGCA) have been involved, with EASA issuing an Airworthiness Directive. Essentially, this means a critical safety update is needed to prevent potential hazards and ensure the continued airworthiness of these widely used aircraft.

बहुविकल्पीय प्रश्न (MCQ)
1. Consider the following statements regarding aviation safety regulations and directives: 1. The European Union Aviation Safety Agency (EASA) is the primary body responsible for issuing Airworthiness Directives (ADs) for all aircraft operating globally, irrespective of their country of manufacture or registration. 2. An Airworthiness Directive (AD) is a legally binding notification issued by a national aviation authority to correct an unsafe condition in aircraft, engines, propellers, or appliances. 3. India's Directorate General of Civil Aviation (DGCA) is responsible for the safety oversight of civil aircraft operations within Indian airspace and for Indian-registered aircraft globally. Which of the statements given above is/are correct?
- A.1 and 2 only
- B.2 and 3 only
- C.3 only
- D.1, 2 and 3
उत्तर देखें
सही उत्तर: B
Statement 1 is incorrect. EASA is the aviation safety agency for the European Union and its member states. While its directives have global implications for aircraft manufactured in the EU, it does not issue ADs for *all* aircraft globally. National aviation authorities (like the FAA in the US, DGCA in India) are responsible for aircraft registered in their respective countries. Statement 2 is correct. An Airworthiness Directive (AD) is indeed a legally binding notification to address unsafe conditions. Statement 3 is correct. The DGCA is India's primary regulatory body for civil aviation safety oversight.
2. In the context of modern aircraft flight control systems, consider the following statements: 1. Fly-by-wire systems replace traditional mechanical linkages with electronic interfaces, allowing for greater precision and integration with flight computers. 2. Ailerons are primarily responsible for controlling the pitch (nose up/down) of an aircraft, while elevators control the roll (wing up/down). 3. The Airbus A320 family extensively uses fly-by-wire technology, which incorporates 'flight envelope protection' to prevent pilots from exceeding aircraft structural or aerodynamic limits. Which of the statements given above is/are correct?
- A.1 only
- B.1 and 2 only
- C.1 and 3 only
- D.2 and 3 only
उत्तर देखें
सही उत्तर: C
Statement 1 is correct. Fly-by-wire technology is a fundamental shift from mechanical to electronic control, enabling advanced functionalities. Statement 2 is incorrect. Ailerons control roll, and elevators control pitch. The statement swaps their functions. Statement 3 is correct. The A320 family is renowned for pioneering advanced fly-by-wire systems, including flight envelope protection, which is a key safety feature managed by onboard computers.
3. Which of the following statements is NOT correct regarding software safety and reliability in critical aerospace systems?
- A.Software used in critical flight control systems typically adheres to stringent certification standards like DO-178C, which mandates rigorous testing and verification processes.
- B.Redundancy, involving multiple independent computing channels, is a common design principle in avionics to prevent single-point failures from compromising flight safety.
- C.The primary challenge in ensuring software safety in aerospace is solely the prevention of coding errors, as external cyber threats are largely irrelevant to embedded flight systems.
- D.Airworthiness Directives (ADs) can be issued specifically for software-related issues, mandating updates or modifications to address identified vulnerabilities or glitches.
उत्तर देखें
सही उत्तर: C
Statement C is NOT correct. While preventing coding errors is crucial, it is not the *sole* challenge. Software safety in aerospace also encompasses design flaws, integration issues, human-machine interface considerations, and increasingly, protection against external cyber threats. Embedded flight systems are not immune to sophisticated cyberattacks, and cybersecurity is a growing concern for aviation. Statements A, B, and D are all correct practices and facts related to aerospace software safety.
