FANS allows improved communication and surveillance capability with the aircraft, to avoid misunderstanding between ATC and the flight crew as well as improving information visibility.

FANS A+ Improves Data Link communication in Oceanic and Remote Airspace FANS B+ Improves Data Link communication primarily in High density airspace

HUD is a transparent display with symbology focused to infinity. It superimposes aircraft information on the external world.

The Automatic Dependent Surveillance Broadcast (ADSB OUT) is the capability of the equipment to automatically transmit, via data link, some onboard parameters such as flight Id., velocity, position... to the Air Traffic Control.

The FAA were the first authority to propose a mandate for In-Service aircraft and this was subsequently followed by other local authorities. The Chinese authorities also now require full fleet compliance by 2024.

The system is fitted as standard on line-fit aircraft today.

The system conditions air from the engine bleed prior to passing it through an Inert Gas Generating System, before entry into the aircraft centre fuel tank.

Halon used as an extinguishing agent is forbidden as per: Montreal and Kyoto protocol and ICAO statement.
From 2025, all portable fire extinguishers on in-service aircraft must be replaced by halon-free equipment.
You can replace all cockpit and cabin portable fire extinguishers by HAFEX bottles. HAFEX is the lightest alternative to existing halon extinguishers and weighs only 2.4kg per bottle (including 1.6kg of 2BTP agent and a bracket).
 

TCAS 7.1 improves reversal logic in case of RA (Resolution Advisory) displaying a new “Level Off” aural message instead of “Adjust Vertical speed”

An Underwater Low Frequency Location Beacon transmitting on a frequency of 8.8 kHz instead of 37,5 kHz multiply by 4 the transmission range. (5 km for a conventional ULB, 22 km for a low frequencies)
