Halon Replacement in Aviation Industry

ICAO has mandated the use of Halon replacements in fire extinguishers used on civil transport aircraft. The Halon replacement cut off dates in ICAO SARPs contained in Annex 6 and 8: Lavatory fire extinguishing systems - 31 Dec 2011 Portable fire extinguishers - 31 Dec 2018 Engine and APU fire extinguishing systems - 31 Dec 2014 Cargo compartment fire extinguishing systems - 28 Nov 2024 Halon still remains one of the most effective fire extinguishing agents available. However, there is no new production. Halon is considered a clean agent by The National Fire Protection Association because it’s electrically non-conducting and does not leave a residue. Halon has an extremely high potential to deplete the ozone layer and contribute to global warming. On January 1, 1994, Halon production ceased in compliance with the Montreal Protocol and the U.S. Environmental Protection Agency. The ozone layer is a region of the upper atmosphere containing relatively high concentrations of ozone (O3) mo...

GAGAN India

GAGAN is GPS Aided GEO Augmented Navigation (GAGAN) based LPV Approach Procedures. This is a great achievement and major milestone in field of Air Navigation Services (ANS) in the history of Indian Civil Aviation. India is the first country in Asia Pacific Region to achieve such a landmark. LPV (Localizer Performance with Vertical Guidance) permits aircraft guided approaches that are operationally nearly equivalent to Cat-I ILS, without the need for ground-based navigational infrastructure. The service relies on the availability of GPS and GAGAN Geo Stationary Satellites (GSAT-8, GSAT-10 and GSAT-15), launched by ISRO. GAGAN is an Indian Satellite Based Augmentation System (SBAS) jointly developed by AAI and ISRO. It is the first such system developed for India and neighboring countries in the equatorial region. GAGAN System was certified by DGCA in 2015 for Approach with Vertical Guidance (APV 1) and en-route (RNP 0.1) operations. There are only four Space-Based augmentation systems a...

EASA proposes use of new technology to support all-weather operations

The European Union Aviation Safety Agency published a proposal to update the regulatory framework applicable to all-weather operations (AWOs) and flight crew training to allow the application of latest technological advancements. This proposal would increase the number of medium-sized aerodromes which are accessible for flight operations. The concept of all-weather operations refers to the ability of aircraft to take off and land in an airport under low visibility conditions. In such circumstances, technological support can ensure safe operations in situations that would otherwise pose safety challenges. While large aerodromes are, for the most part, already equipped for such operations, medium-size or regional airports had typically so far been unable to afford the investment required. “This Opinion is innovative in certifying the use of technologies that are already available to increase safety, while at the same time broadening the commercial network by increasing the accessibility ...
